SPI Communication between Nordic Semiconductor DK51 board (Master) & Arduino UNO (Slave)

SPI Master/Slave comm for DK51-Arduino UNO

SPI Communication between Nordic Semiconductor DK51 board (Master) & Arduino UNO (Slave)

DK51 board will send periodically a set of command with parameters and data to Arduino SPI Slave. The latter will send back ACK or NAK response to SPI Master.

This project is based on spi_master_with_spi_slave example by Nordic Semiconductor that can be found in nrf51 SDK
