IqRF Click Board

Code examples for the IQRF Click Board™, written for MikroElektronika hardware and compilers are available on Libstock.

Code Snippet

This code snippet contains receiver and transmitter code for the IQRF Click Board™ working with the Thermo K Click Board™. When in transmit mode, MCU reads the temperature from Thermo K and if a certain threshold has been reached, byte data is sent to IQRF board via UART communication. Then, IQRF is broadcasting that byte to every other IQRF within range. Every Other IQRF click board is receiving that byte via RF communication and sending data to his local MCU via UART. Every event is displayed on easyTFT.
