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

This example demonstrates the use of SPI SCB (Serial Communication Block) resource for PSoC 4 MCU in master mode

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

CapSense Flanking Sensor Suppression in PSoC 4. This code example implements Flanking Sensor Suppression (FSS) in PSoC™ 4 devices. FSS eliminates false touches by distinguishing between signals from closely spaced buttons.

Add flash and chip protection settings for psoc4 devices into the hex file

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

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

This example demonstrates the use of SPI SCB (Serial Communication Block) resource for PSoC 4 MCU in slave mode.

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

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

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 demonstrates how to transition PSoC 4 MCU among the different power modes.
