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

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

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 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 is a minimal starter application template for PSoC™ 4 devices.

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

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

This code example demonstrates the use of the multi-frequency scan (MFS) for PSoC™ 4 CAPSENSE™ applications to prevent false touch detection in the presence of external noise. This code example demonstrates this feature for both CSD (self-capacitance) and CSX (mutual-capacitance) designs.
