diff Small_CPU/Src/spi.c @ 264:b3685fbada3b IPC_Sync_Improvment_2
Sync to Main 100ms time stamp & added Reinitialization of globals after startup
Added function to synchronize RTE to the timestamp provided by Main 100ms callback. This was introduced to compensated small shifts in execution and program flow shifts (for example during long operation times)
