AN42137 - Capsense™ Express Software Tool http://www.cypress.com/?rID=34293 This application note explains how to use the CapSense(TM) Express software tool to configure the CapSense Express device. In addition, tuning parameters for required functionalities is also described.

-->

This application note explains how to use the PSoC Designer System Level Design to configure the CapSense Express device. How to tune the parameters for required functionalities is also described. This document expects user to a basic level of familiarity with PSoC Designer System Level Design.

Introduction

The CapSense Express Controller enables the control of a maximum of 10 IOs configurable as either capacitive sensing elements (used as buttons or combined to form a slider), or GPIOs, driving LEDs or interrupt signals, based on various IO conditions. The GPIOs are also configurable with interrupt for waking up the device from sleep. The user can configure buttons, outputs, and parameters, through specific commands sent to the I2C port. The IOs pin mapping flexibility (capacitive elements and GPIO functions) enables easy PCB trace routing and reduces the PCB size and stack up. CapSense Express products are designed for easy integration into complex products.

AN56691 - CapSense® Express™ – Creating Reference Designs with 1CS/2CS Button Devices http://www.cypress.com/?rID=38976 CapSense® Express™ family of configurable devices provides a quick way to implement touch sensing functionality. The One- and Two-button devices can easily replace mechanical switches in applications requiring low pin count devices. This application note explains how to create simple reference designs with the CY8C20111/CY8C20121 devices and also demonstrates the functionality of these devices through example projects.

Introduction

CapSense Express is a family of high-performance, fixedfunction devices that provides a robust solution for simple designs (involving few buttons, slider, LEDs and general purpose I/Os). CapSense Express controllers support two capacitive sensing (CapSense) buttons and two generalpurpose outputs in CY8C20121 and one CapSense button and one general-purpose output in CY8C20111. The host controller can configure these as I2C slave devices and read the sensor information in real time. A software tool is also provided for achieving optimal performance in real time using a GUI. These are plug and play devices with factory default settings. The 1B/2B devices achieve CapSense functionality without requiring any external components. The ease of use of these devices leads to reduced cost and less time to market the solution.

Configuring a CY8C201xx Device for Use Either with External Pull-ups or With a Master Operating at Different VDD – KBA80735 http://www.cypress.com/?rID=64957 Answer: The CY8C201xx devices support internal pull-up resistors on I2C lines. Table 1 shows the factory default settings for internal pull-up resistors.
 

Table 1: Factory Default Values for Internal Pull-Up Setting
 

Device
Internal Pull-Up (factory default)
CY8C20111/21
Disabled
CY8C201A0
Enabled
CY8C20110/80/60/40/42
Enabled


The setting for the internal pull-up resistors must match the requirements of the overall design. When the setting is incorrect, the following problems can occur:
 

  • Pull-ups should be sized correctly to meet rise time and IOL requirements in an I2C design. Use of internal pull-ups enabled in combination with external pull-ups in a CapSense® device reduces the effective resistance. Proper bus operation is not guaranteed.
  • Consider the scenario in which the CapSense device operates at 3.3 V with internal pull-ups enabled while the master operates at 1.8 V and external pull-ups pull the bus to 1.8 V. Bus voltage (VIH) seen by the master is between 1.8 V and 3.3 V due to the voltage divider formed by internal and external pull-ups. This condition can damage the master device.
     
In the above scenarios, it is recommended to DISABLE the internal pull-up resistor. This has to be done during the device configuration, before soldering it in the end system. To enable or disable the internal pull-up resistors, configure the I2CDM bit (MSB) in the I2C_ADDR_DM (7Ch) register. For more information, see CY8C201xx : Register Reference Guide.
