examples/spislv_test: Added app that allows users to test SPI Slave comm
This application continuously reads the file system of the spislv. Each
received message will be written to the user in hexadecimal form, and the same
received data will be sent back. In this way, the user can test if their spislv
driver and hardware setup are working properly before proceeding further.
On a master device, using the SPI tool, when sending the message: spi exch
-x 4 deadbeef
The slave device will output:
Slave: 4 Bytes read
Value in hex form from /dev/spislv2: de ad be ef
Slave: Writing value back to /dev/spislv2
