Expected result
===============
You should be presented with the RIOT shell, providing you with commands to initialize a board
as master or slave, and to send and receive data via SPI.

Background
==========
Test for the low-level SPI driver.

## Default SPI CS pin

To overwrite the optional default cs pin CFLAGS can be used:

`CFLAGS="-DDEFAULT_SPI_CS_PORT=<my_port_int> -DDEFAULT_SPI_CS_PIN=<my_pin_int>" BOARD=<my_board> make flash term`

tests/periph_spi: Expose default SPI CS pins Expose the option to use default cs pins defined as DEFAULT_SPI_CS_PORT and DEFAULT_SPI_CS_PIN. This is used if a wiring environment is already defined. CFLAGS can be used to define the CS pin from the environment provided allowing easier automation of tests. 2020-05-19 17:07:11 +02:00
