Hi,
I am using S32DS SDK to test ADC on MPC5748G DEVKIT. My ADC input pins (channels) are PB4, PD4 and PD5.
My test result shows sometimes ADC calibration failed at ADC_Init().
Register ADCx_CALBISTREG reports failure at bit 28.
Failures can still happen even inputs are connected to 3.3V or GND.
May I know which cases will make ADC calibration fail?
Thanks
Travis
Hello,
Could you please be more specific?
I expect you are using ADC example from SDK which is embedded in S32DS. Am I correct?
I see in following execution not matching reference manual:
and ref manual requires:
Try to switch those 2 lines of code to see if this has any impact.
regards,
Peter
