Using a custom board.

Used CubeMX and CubeIDE to develop the code which is attached to this post.

A read of WHO_AM_I_A results with the command in rxData[0] and nothing in rxData[1].

Same thing happens when reading registers.

Hello @JBonn

Please use the BSP driver for LSM303AGR to set your spi and read your data.
