Introduction

This example demonstrates the MibSPI RX and TX operation configured in blocking and DMA mode of operation.

This example sends a known data in the TX mode of length APP_MIBSPI_MSGSIZE and then receives the same in RX mode. Digital loopback mode and DMA is enabled to transmit and receive data.

When transfer is completed, TX and RX buffer data are compared. If data is matched, test result is passed otherwise failed.

Supported Combinations
