Hello,
I am using with i.MX1176 and MCUXpresso IDE. 1176 ADC is 12bit. The IRQ function and LPADC settings are as follows:
When i read convValue from IRQ function, it is greater than 12-bit. I read values up to 15-bit. Is it possible?
Thanks,
Hi @SpeedyGonzalesss ,
Thanks for your interest in NXP MIMXRT series!
This is not possible, the maximum measurement range of a 12-bit ADC is 0~4095. If your reading is out of range, there should be a problem with the intermediate processing. Please note if your sampleScale is configured? It is recommended to experiment with known voltage measurement points first.
Best regards,
Gavin
Is there any answer for this question?
