adc 12 bit #110
Comments
At first glance, seems like a bug to me. I thought that maybe ArduinoCore-sam/system/libsam/source/adc12_sam3u.c Lines 243 to 246 in c893c62
And that register contains the 12-bit ADC value in the lower 12 bits: (Note that the upper 4 bits can contain the channel number, but only if enabled, so I suspect this is not the case here and these are always zero and can be ignored). Do you happen to have a Due you could test if this is indeed broken? Should be easy, if all |
I can't test it. I don't have DUE with SAM3U4E |
Why is it converted to 10 bit if the next line assumes it is 12 bit wide.
