I'm testing the ADC component of FRDM-KE02Z and I've set the conversion time and channels as shown
Then I've created a TU1:TimerUnit_LDD to trigger the ADC conversion every 312.5us and write the next lines in the TU1_OnCounterRestart ISR.
Finally here's the signal capture on the oscilloscope for checking the ISR process.
The sampling time and acquired values are okay but I expect an ADC process of 20us as I set 2 channels and a conversion time of 10us. Why I get more than 40us?
