Hi Champs,

Can you please let me know if

1: ADC can work in polling mode?

2 How fast is the ADC of AM335x? How many 12 bit conversions it can churn out in a second

Best Regards

Feroz,

1. You can pole the FSM_BUSY bit in the ADCSTAT register to determine when the ADC has finished its conversion. Once the ADC is finished you can read out the new data.

2. 200K samples / second

Tyler
