annotate Small_CPU/Src/externalInterface.c @ 861:ad96f99ebc78 Evo_2_23 tip
Synchronize ADC and UART activities:
depending on the cable configuration the UART sensor operation may have an impact to the ADC measurement (peaks). To avoid this the ADC measurements are now only started in case no UART communication is pending.
