I'm currently working on ArgonKey, which is a 96 board with a STM32F412
plus a bunch of motion and environmental sensors.
I'm exploring the possibility to put in place the communication from
HiKey to ArgonKey and I noticed that the stm32 SPI environment already
implements the SPI_SLAVE communication. Does somebody have already tried
it out and know what the status is? Is there any example (doesn't seem
so) where I can get a look from?
