Customizing PSoC Designer™ User Modules

Thu, 02 May 2013 05:58:44 -0600

The objective of this guide is to create an improved user module (Timer16X), using the old user module (Timer16) as a template, with the help of the “User Module Customization Wizard” available in PSoC Designer™ 5.4. This guide describes how to modify an existing user module to meet your needs. The “User Module Customization” feature allows you to create a copy of an existing user module and export it.

Each user module is a combination of information on the interconnections of PSoC resources and the software used to control them. It is possible to generate new UMs or customize existing UMs. Different UMs can be combined to produce a new UM. These new UMs can be similar to the old ones, with no hardware changes and only with API changes.

AN78920 - PSoC® 1 Temperature Measurement Using Diode

Thu, 04 Apr 2013 06:03:05 -0600

The temperature is measured based on the principle of a diode’s forward bias current dependence on temperature.

Introduction

PSoC 1 – CY8C28xxx family has on-chip 8-bit IDAC, and a 14-bit Delta Sigma ADC, which enable accurate and high-resolution temperature measurements using an external diode-connected transistor. The example projects attached with this application note work with CY8CKIT-036 – PSoC Thermal management EBK.

There are various sensors available for measuring temperature such as Thermistor, Thermocouple, resistance temperature detectors (RTD). Choosing a sensor or method to employ for measuring the temperature depends on factors such as the accuracy requirement, the temperature range to be measured, and the cost of the temperature sensor. The diode based temperature measurement is an easy, accurate, and also relatively low-cost method for measuring the temperature.

"Old Style Function Definition" Warning in PSoC® Designer™ 5.0, 5.1, and 5.2 – KBA 83779

Thu, 04 Apr 2013 05:26:31 -0600

Answer: The new ImageCraft compiler (used with PSoC Designer 5.0 Service Pack 4.5, Designer 5.1, and Designer 5.2) is more compliant to the ANSI C standard.

Previous versions of PSoC Designer allowed you to leave the argument list blank in function definitions. For example:

void main()

{

}

If you attempt to compile this code with the new ImageCraft compiler, you will receive an “Old Style Function Definition for 'main' ” warning. This warning can be safely ignored; however, you can eliminate this warning by adding void to the argument list.

void main(void)

{

}

PSoC Designer 5.3

Fri, 22 Mar 2013 16:23:20 -0600

New Features

PSoC Designer 5.3 contains a host of upgrades to make the software easier to learn for and easier to use. New features include:

Download Help

Auto-routing: Vastly simplifies wiring the connections in the chip view, making it easier to learn for beginners and quicker to use for experts. Simply shift+click on a block port and a number of glowing, golden lines will show you all the possible destinations. A second click on one of those highlighted locations and you're done! This works on analog routes as well as digital routes, block-to-block or block-to-pin.

Upgraded device catalog: It is now far quicker and easier to find the device for your project. You can filter the device list based on chip characteristics (such as pin count, package or available peripherals) or by typing in a substring of your part number. You can also save frequently used devices as favorite and see the supported user module list for any device at a glance.

Cleaner user module customization: Designer 5.3 makes it far simpler to customize user modules, providing two ways to modify their behavior. First, user modules can be copied and renamed, allowing users to change the hardware configuration or APIs. These customer user modules become part of your UM library and may be used in any PSoC Designer project. You can also export these customer user modules to a single zip file and import them into any other version of Designer 5.3 or later.

For smaller changes, we have also made it easier to change the APIs for a user module instance in your project. Simply right-click on your user module instance and you can lock it, preventing any future “Generate Project” commands from over-writing your changes.

Other ease-of-use enhancements: Cypress applications engineers have specified 12 user interface changes to make the chip view more readable and usable, including the ability to zoom with the scrollwheel. In addition, we have streamlined the project creation GUI, minimizing excess clicks. Finally, we give you the ability archive your projects.

New User Modules

PSoC Designer 5.3 contains a 8 completely new user modules. Four of the existing user modules have received significant upgrades as well.

VoltageSequencer allows you to control the ramp rates and delays between your power supplies with a simple GUI.

SMBusSlave allows your PSoC to communicate with this widely used system management protocol.

FanController will control up to four fans using hardware PWM blocks in either open loop or closed loop (with tachometer) modes.

Thermistor provides the hardware interface and software APIs to measure temperature with compensation via lookup table or the Steinhart-Hart equation.

SmartSense2X eliminates the need for tuning in your dual-channel CapSense solutions. Available for CY8C2xx45 devices.

CSD2X has been enhanced to provide support for background scanning and FMEA support, which detects faults in your system.

GasSensorAFE implements a bias circuit and transimpedance amplifier to measure the output of a 3-lead electrochemical sensor with current output.

SwitchCapConfig allows easier configuration of the programmable analog blocks such that you can quickly build amplifiers, integrators and comparators with them.

EzADC streamlines the setup of your ADCs, minimizing the possibility of erroneous clocking or sample rates.

Finally, the filter accuracy of LPF2 and BPF2 have been improved up to 5%

Installation Notes

PSoC Designer 5.3 will co-exist with your previous versions of PSoC Designer. You do not need to uninstall those previous versions, and this new version will not impact the existing ones in any way

Using a PRS Generator as a PWM - KBA83077

Tue, 19 Mar 2013 02:02:57 -0600

Answer : The PRS generator uses a Linear Feedback Shift Register (LFSR) to generate a pseudo-random bit stream. You can configure the PRS to output the LSB of the bit stream in order to implement a PRS PWM. Using a PRS PWM spreads the signal energy over the complete spectrum and significantly lowers EMI.

The PRS Pulse Width Modulator example project demonstrates how to implement a PRS PWM. It also compares the frequency spectrum of a PRS PWM with a conventional PWM.

AN78646 - Integrated Power Manager using PSoC® 1

Mon, 18 Mar 2013 03:54:10 -0600

Introduction

Computing and communication systems are complex and comprise multiple subsystems. Each subsystem can have its own voltage domain, which is also known as a power rail. Each power rail needs to be powered up and monitored individually. This creates a need for power management. Because this activity is a health indicator of the system, it cannot be incorporated in any of the subsystems. For this reason, a dedicated chip is used.

Power management consists of the following parts:

accurate and reliable voltage sequencing
rapid power rail fault detection
voltage and current monitoring of power rails to optimize power consumption
real-time trimming for closed-loop control of power converters (voltage regulators)
in-system margining
fault/event logging in EEPROM
communication with the host controller using I2C, SMBus, or PMBus

Project Archive in PSoC® Designer™ 5.3 - KBA85754

Thu, 14 Mar 2013 08:01:17 -0600

Answer: The projects archived using PSoCDesigner 5.3 cannot be opened if the both of the following are true:

Projects were originally created with PSoC Designer 5.2 or earlier releases;
Projects were archived using PSoC Designer 5.3 with 'Minimal' option;

The message “Some of files supporting this project have not been installed.” appears in the Status Bar.

Root Cause

There is a bug in PSoC Designer 5.3 software due to which the PSoCConfig.xml file is not included in the archive for the projects that were created with earlier PSoC Designer releases and if the "Minimal" option is chosen for archiving. This bug will be fixed in the next PSoC Designer release. 'Complete' and 'Bundle' are the only archiving options recommended to be used in PSoC Designer 5.3. There are no issues with the 'Minimal' archiving option for the projects that were initially created in PSoC Designer 5.3.

Workaround

Use 'Complete' or 'Bundle' archiving options in PSoC Designer 5.3. Omit using 'Minimal' option for archiving projects created with PSoC Designer 5.2 or earlier releases.
If there is a need to use the 'Minimal' option, you must manually perform one of the following actions:
1. Update the archive manually - copy the PSocConfig.xml file from the original project to the archive. The PSocConfig.xml file must be located on the same level as main.c.
2. Rename the PSocConfig.xml file before archiving with the 'Minimal' option. Rename PSocConfig.xml to PSoCConfig.xml in the original project and then archive the original project with the 'Minimal' option again.

AN2017 - PSoC® 1 Temperature Measurement with Thermistor

Tue, 29 Jan 2013 02:47:47 -0600

The associated project measures the resistance of a thermistor to calculate its temperature using lookup tables and equations, and is also used with other PSoC 1 devices that have the required resources.

A thermistor is a temperature-sensitive resistor in which resistance varies with temperature. There are two types of thermistors: positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors. This application note describes the more commonly used NTC thermistors, in which resistance decreases with increase in temperature. Based on this principle, temperature is calculated by measuring the resistance.

AN2094 - PSoC® 1 - Getting Started with GPIO

Thu, 24 Jan 2013 05:34:59 -0600

今日本語で !!

General-purpose input and output (GPIO) is a very critical part of any microcontroller unit (MCU) as they form the bridge between the external world and the MCU. The type and nature of this external world bridge depends on the end application. For instance, an ADC requires a GPIO to be an analog pin whereas an I2C or SPI digital communication block requires the same GPIO to be digital. In order to properly setup this external world bridge, you need to know not only the end application but also the GPIO system of the MCU that is used. PSoC like any other controller has its own GPIO system. This application note discusses the application specific parameters of the GPIO system. Detailed technical overview of the system can be found in the respective device technical reference manual (TRM) under General Purpose I/O chapter of PSoC Core section.

AN78692 - PSoC® 1 - Intelligent Fan Controller

Wed, 02 Jan 2013 01:10:01 -0600

This application note explains how to considerably reduce development time of fan control systems. The application note assumes that you are familiar with PSoC 1, PSoC Designer IDE, and programming in C.

Introduction

System cooling is a critical task in any high performance electronic system. As circuit miniaturization continues, increasing demands are placed on system designers to improve the efficiency of their thermal management designs. Usually thermal management is done by forced convection. In forced convection the heat dissipation is increased by moving the air inside and around the heat source. This can be easily accomplished using Brushless DC (BLDC) based fans. The speed of these fans depends on DC voltage across these fans.

AN2014 - Basics of PSoC® 1 Programming

Wed, 26 Dec 2012 07:09:28 -0600

PSoC 1 devices can be programmed after they have been installed in a system. In-circuit programming is convenient for prototyping, manufacturing, and in-system field updates. This allows a PSoC 1 device to be programmed during prototyping, later in the manufacturing flow, or reprogrammed in the field at a later date. PSoC 1 uses in-system serial programming (ISSP) protocol for programming. ISSP is a two-wire protocol that uses a bidirectional data line (SDATA) and a clock line (SCLK) from the host to PSoC 1 to perform device Programming. There are various Programming tools that are available to program PSoC 1 using ISSP protocol. PSoC 1 supports two ISSP modes: Reset and Power Cycle programming.

AN2336 - PSoC® 1 - Simplified FSK Detection

Tue, 11 Dec 2012 20:28:41 -0600

Frequency shift keying (FSK) is the modulation cornerstone of a number of digital data transmission systems. The transmit signal is fairly easy to generate, AN67391 discuss the implementation in detail. Receive processing is tolerant of a wide range of signals and relatively immune to a large class of interfering signals.

This Application Note outlines a simple, almost all-hardware method for detecting FSK signals using the analog signal processing capabilities of the PSoC 1 device. It describes circuits and signal processing techniques for demodulation. This signal processing technique is readily applicable to caller ID and several modem standards but it is not a complete modem; it does not include the phone line or other interfaces; it also does not include the data processing code.

A separate project is included and outlined in the Appendix A to simplify testing of the demodulator.

In order to be able to understand the implementation, following pre-readings are suggested:

AN2226 - PSoC® 1 - Using Correlated Double Sampling to Reduce Offset, Drift, and Low Frequency Noise

Tue, 11 Dec 2012 20:23:33 -0600

Introduction

The thermocouple (TC) is a voltage output device that measures the temperature difference between the sensor tip and a reference junction (called the cold junction). This is a relative measurement and to be accurate, the reference lead temperature must also be known. Type K thermocouples have an average output of approximately 40.7 μV/°C. This output is approximately linear.

Correlated Double Sampling (CDS) provides a means to efficiently subtract offset and remove drift, and low frequency noise from this sensitive measurement. This technique works just as well for differential measurements such as pressure sensors and load cells.

Reading the following application notes will aid in better understanding of this application note:

AN74170 – PSoC 1 Analog structure and configuration with PSoC Designer - Discusses in detail about the architecture of analog blocks in PSoC 1 and how they can be configured to implement a particular functionality.

AN2223 - PSoC® 1 - Approximating an Opamp with a Switched Capacitor Integrator

Tue, 11 Dec 2012 20:21:45 -0600

Opamps have simplified circuit design for engineers. They form a basic building block for the analog and mixed-signal design. PSoC 1 analog blocks, both continuous time (CT) and switched capacitor (SC) do not have a native opamp mode. They are wired so that they can create PGAs, INSAMPs, Filters, Integrators, and so on. However, in some designs only a plain opamp is required. This application note shows how to configure a switched capacitor block so that it approximates the functionality of an opamp.

The application note discusses the following topics:

A brief explanation of how an opamp works.
An explanation of how a switched capacitor integrator can emulate an opamp (faux opamp).
Examples of faux opamp circuits.

This application note does not give in depth information about switched capacitor blocks. For more information please refer AN2041 PSoC 1 – Understanding PSoC 1 Switched Capacitor Analog Blocks.

AN2165 - PSoC® 1 - Implementing Direct Sequence Spread Spectrum in the PSoC

Tue, 11 Dec 2012 20:15:52 -0600

Spread spectrum RF transmission involves spreading out the power spectrum of an RF signal using a code. The same code is then used to receive the signal. This has some tremendous benefits, including shared bandwidth between multiple users using multiple codes, reduction of interference experienced by other users of the spectrum, and resistance to external interference, jamming, multipath effects, and eavesdropping. Spread spectrum usually involves changing the transmission frequency of a signal over time (frequency hopping) or combining a signal with a pseudo-random (PN) spreading code before transmission (direct sequence, or DS).

This application note presents an example design for implementing the baseband functions of a Direct Sequence Spread Spectrum (DSSS) transmitter with the PSoC® 1 programmable system on-chip.

AN2161 - PSoC® 1 Analog - Voltage-to-Frequency Converter

Tue, 11 Dec 2012 20:09:10 -0600

Voltage-to-frequency (V/F) converters are widely used in industrial electronics, frequency-shift keying modulators, phase-locked loop systems, analog-to-digital converters, isolation amplifiers, etc. Even though these converters are produced as standalone devices, they still require several external components and are relatively expensive in comparison to modern low-cost analog integrated circuits. The PSoC allows the designer to build the V/F using only one continues continuous time (CT) analog block (configured as schmitt trigger) and one switched capacitor (SC) analog block (configured as integrator), without any external analog components. All digital blocks, and the CPU, are at user disposal. The designer will get a useful device function with virtually no additional cost or extra components. Moreover, the proposed V/F converter produces both meander and symmetric sawtooth signals, which are useful for some applications such as analog PWM modulators and capacitance meters.

General Description:

The Voltage Sequencer User Module is a flexible and easy way to implement voltage sequencing function using a PSoC 1 device. Voltage sequencing is required to ensure reliable power up and power down of power rails in a system and flag a fault condition in case of a failure. The User Module Wizard allows you to control ramp timing as well as time delays between power rails. Voltage sequencing is popularly used in computing (servers, storage arrays) as well as communication (basestation, routers, VOIP equipments) systems in addition to general industrial and consumer systems.

The User Module enables PSoC 1 to read PGOOD (power good) signals from power regulators and generate EN (enable) signals for power regulators based on user-defined ramp timing. If PSoC 1 does not receive the PGOOD signal in the user-defined 'RAMP' time, then it asserts a power-up failure interrupt and continues with the user-defined power-down sequence, if the auto power-down mode is enabled. This User Module uses an on-chip 16-bit timer (implemented using programmable digital blocks) to generate user-defined time delays.

Once you place this User Module in your design it configures all required hardware resources. This User Module provides an output voltage that is proportional to the gas concentration.

The Gas Sensor AFE User Module consists of two blocks - a control amplifier and a trans-impedance amplifier (TIA). Control amplifier is implemented using one continues time (CT) analog block and one switched capacitor (SC) block of PSoC 1. It is used to maintain the sensor’s required bias voltage.

The sensor provides current output proportional to the gas concentration. TIA (implemented using a CT block) converts this current signal to voltage.

Features:

Implements configurable AFE for a three-lead electrochemical sensor
Provides Control Amplifier to drive and control the gas sensor
Provides TIA to convert the sensor current output to voltage

General Description:

The Fan Controller User Module in PSoC Designer helps you control up to eight, four-wire fans in open-loop or closedloop mode. The Fan Controller User Module wizard enables you to select the number of fans and their configurations. Some key applications of Fan Controller are in servers, computers, projectors etc.

The Fan Controller User Module changes the fan speed using hardware PWMs implemented in programmable digital blocks in PSoC 1. It measures fan speed by reading tachometer output using a 16-bit timer and a hysteresis comparator.

In open-loop mode, PSoC 1 sets the user defined PWM duty cycle irrespective if the current fan speed. However, application programming interface (API) is provided to measure the fan speed. In closed-loop mode, a desired fan speed is achieved by PSoC 1 by controlling PWM duty cycle based on the difference between desired and current speed. In open-loop mode, this User Module supports multiple fans to be connected to the same PWM signal called “banks”.

Features:

Open-loop and closed-loop control of four-wire BLDC fans
User Module wizard to select the number of fans and their configuration
Fan speeds ranging from 450 to 25,000 RPM
Fan stall/rotor lock condition detect on all fans

Warning: Machine Instructions Inside .LITERAL/.ENDLITERAL Labels - KBA83511

Thu, 18 Oct 2012 03:39:20 -0600

Answer: This is the warning added in Imagecraft compiler V7.05 onwards. The .Literal and .EndLiteral directives are used to instruct the compiler that the content placed within these directives should not be compressed. In general, these directives are used if any custom data table needs to be placed in flash, which should not be altered by code compression. If any machine instruction code is placed within these directives, it will not be compressed and the user will be notified with the warning mentioned above. This warning can be safely ignored if the user prefers the code within these directives not to be compressed.
