annotate Discovery/Src/simulation.c @ 220:e524a824d8f2 Improve_IPC_Sync
Added schedule point for functions executed once in a second
SPI communication takes place every 100ms triggered by the master (main). Synchronisation is done using the SPI RX complete callback which is called ~4ms after communication was started. In the previous implementation this could happen in parallel to usage of data. To solve this potential problem the execution of functions called once a second was moved from 1000ms to 980ms giving a 20ms window for execution.
