AM263Px MCU+ SDK  10.01.00
MCSPI Loopback

Introduction

This example demonstrates the McSPI RX and TX operation configured in blocking, interrupt mode of operation.

This example sends a known data in the TX mode of length APP_MCSPI_MSGSIZE and then receives the same in RX mode. Internal pad level loopback mode is enabled to receive data. To enable internal pad level loopback mode, D0 pin is configured to both TX Enable as well as RX input pin in the SYSCFG.

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