This code example demonstrates the UART transmit and receive operation in PSoC 4. The application uses a serial terminal to read data and to echo back the received data. The UART resource is configured to do both transmit and receive operations.

This example project demonstrates the basic operation of the emulated EEPROM middleware.

This code example demonstrates the use of a GPIO configured as an input pin to generate interrupts on PSoC® 4. The GPIO signal interrupts the CPU and executes a user-defined Interrupt Service Routine (ISR).

This example demonstrates the operation of the I2C block for PSoC 4 in Slave mode using callbacks.

This example demonstrates the operation of I2C resource for PSoC 4 in Master mode with an EzI2C slave. The I2C master is configured to send command packets to control a user LED on the slave. Both the slave and master are on the same device.

This example demonstrates the use of PSoC 4 Watchdog Counters in cascaded mode. The user LED is toggled every time the Counter2 interrupt occurs. The match values of all the counters are set to toggle the LED every 1 second.

This code example demonstrates how to manually tune a mutual capacitance (CSX)-based button widget in PSoC® 4 devices using CapSense® Tuner GUI.

This example uses a TCPWM block in the Timer/Counter mode to generate a periodic interrupt. An LED toggles whenever the interrupt occurs.

This code example demonstrates how to manually tune a self-capacitance (CSD)based button widget in PSoC 4 devices using CapSense Tuner GUI.

This code example demonstrates simple UART communication by printing a "Hello World" message on a terminal and blinks an LED using PSoC 4.

This code example demonstrates how to manually tune a self capacitance (CSD)-based slider widget in PSoC® 4 devices using CapSense Tuner.

This code example demonstrates how to monitor self-capacitance (CSD) based buttons and slider widgets using the CAPSENSE™ tuner through RTT in PSoC™ 4 devices.

This code example demonstrates a CAPSENSE™ based proximity sensing design to control the brightness of an onboard LED. It will help to learn how to design a proximity sensor using a PSoC™ 4 devices, and see how an approaching hand controls the intensity of an onboard LED.

This code example demonstrates the self-capacitance scanning technique to implement liquid tolerance on mutual-cap sensors.
