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.

Introduction

   Cypress's Programmable System-on-Chip (PSoC®) integrates a microcontroller with programmable analog and digital peripherals. Because you can configure the resources of a PSoC, you can develop a device that is customized and tuned for your application. Moreover, as the needs of the application change during development and in production, you can reconfigure the device to adapt to these new requirements with minimal effort.

CAN (Controller Area Network) is a serial communication protocol developed by Robert Bosch GmbH in the early 1980s. This protocol was initially developed for automotive applications to communicate between subsystems without a central control. CAN is also being adopted in areas such as embedded systems (CANOpen) and factory automation (DeviceNet). CAN was standardized by ISO in 2003 (ISO 11898-1:2003).

This application note introduces the basic concepts of CAN protocol and demonstrates how CAN bus communication can be implemented using PSoC® 3 and PSoC 5LP (hereafter referred to as PSoC). Four code examples are included with this application note. Examples 1 and 2 together illustrate a simplex communication between two PSoCs. Examples 3 and 4 together demonstrate the Remote Transmission Request (RTR) feature of CAN.

The video talks about how to transmit and receive messages using CAN controller available in PSoC3.

Introduction

The DMA controller (DMAC) in PSoC 3 and PSoC 5LP can transfer data from a source to a destination with no CPU intervention. This allows the CPU to handle other tasks while the DMA does data transfers, thereby achieving a „multiprocessing‟ environment.

The PSoC DMA Controller (DMAC) is highly flexible – it can seamlessly transfer data between memory and on chip peripherals including ADCs, DACs, Filter, USB, UART, and SPI. There are 24 independent DMA channels.

 The following video gives the user a brief description of how to use the DMA on PSoC3 and the different parameters related to it:

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.

PSoC® 3 and PSoC 5LP (hereafter referred to as PSoC) are more than just microcontrollers. With PSoC you can integrate the functions of a microcontroller, complex programmable logic device (CPLD) and high-performance analog with unmatched flexibility. This saves cost, board space, power and development time.

This application note introduces the PLDs in the PSoC Universal Digital Block (UDB), and then teaches how to use them by creating PSoC Creator components. It is an effective first step in porting complex programmable logic device (CPLD) functionality to PSoC. After reading this application note, you should be familiar with PSoC PLDs, and be able to create your own custom Verilog-based components using PSoC Creator™.

Introduction

Have you maxed out your CPU bandwidth? PSoC 3 and PSoC 5LP UDBs can lighten the load on your CPU by creating intelligent custom peripherals. The datapaths in those UDBs can be used to create sophisticated multiprocessor-based designs.

Many PSoC customers have experience writing HDL code for CPLDs or FPGAs. PSoC 3 and PSoC 5LP support Verilog for PLDs. However, PSoC 3 and PSoC 5LP PLDs are smaller than full-fledged CPLDs or FPGAs, and many designs are too large for PSoC 3 and PSoC 5LP. PSoC’s unique datapath modules remove this obstacle by integrating one or more small 8-bit processors into PLD-based designs.

Introduction

Temperature measurements typically use one of four sensors: thermocouple, thermistor, diode, and resistance temperature detector (RTD). The primary criteria for choosing a sensor are cost, accuracy, and temperature range. Although they are more expensive than other sensor types, RTDs have the best temperature accuracy. Calibrated platinum RTDs can achieve accuracy of >0.02 °C in the -200 °C to 850 °C range.

Introduction

When designing with the PSoC 1 family of microcontrollers, you use PSoC Designer and its highlevel interface to configure the PSoC, including the analog architecture. In addition to placing and configuring the individual user modules (building blocks), several global analog parameters also require configuration. Understanding these global parameters and the overall analog architecture is important, especially when a design consists of several analog user modules that are affected by these settings.
 

In the following videos, Dave implements Analog to Digital converters in a project and shows the tools he'll be using for designing robust analog-output sensor signal paths.

Segment LCDs are available in two forms - segment LCD glass and the segment LCD module, which comes with inbuilt driver. Many times, it is difficult to get all the required display features on a LCD module. One possibility is to use a custom LCD glass and an external driver. But this increases the cost of the system. Cypress PSoC chip can do segment LCD glass drive besides executing some other major tasks with its configurable digital/analog hardware and with its 8-bit MCU. It integrates multiple functions of the system within a single chip offering significant BOM savings.

To assist in design development, PSoC Designer provides SLCD user module. It supports following features:

• Multiplexed LCD glass drive, 1/2 bias
• 2, 3 and 4 common LCD drive
• 30Hz to 150Hz refresh rate
• Type A waveform
• Contrast control

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.

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.

Optical sensors based on detection of light beam interruption by moving objects are widely used in automatic door opening systems and are also used in various industrial applications for measuring liquids level in the tanks, goods quantity calculation and movable parts position. These sensors typically consist of a light source and a photodiode and signal detection circuit, which compares photodiode signal level with a reference signal. The main drawbacks of this approach lie in high sensor noise and sensitivity characteristics which can cause false detection. This drawback can be eliminated by using modulated light instead of constant light and using correlation techniques to make decisions about presence or absence of an object between the light source and the photo diode. This approach is demonstrated in this application note using PSoC® Programmable Systems On Chip.

Introduction

Performing multiplication can be tedious without dedicated hardware. Any dedicated hardware multiplier has finite resolution and applications may arise where more resolution is required. This application note describes the techniques that enable the PSoC 1 MCU to quickly multiply multiple-byte-operands and give a full resolution output.

PSoC 1 microcontroller’s external crystal oscillator (ECO) can be used as a reference for timekeeping and other low-speed (<32 kHz) operations. It can also act as the reference for the phase-locked loop (PLL) mode of the internal main oscillator (IMO). The PLL uses the 32.768 kHz input to generate a more accurate 24-MHz clock signal. This is used for operations that require an accurate high-speed clock such as dual-tone multifrequency (DTMF) signal generation and serial communications. Optimal performance from the ECO for each of these functions requires different external components and control register settings.

 

In the following video, Dave explains buffers using a PSoC Designer project.
