ADCTimerTrigger

Readme
 
This is a C language project that demonstrates the analog to digital converter (ADC) using timer-triggered sampling. main samples channel=7 (PA22) at 1kHz. Timer G0 publishes a hardware event (chan=1) every 1ms. ADC0 subscribes the the chan=1 hardware event creating the timer-triggered sampling.
