Hi Peter,
Have noticed similar with EK-TM4C1294-XL launch pad ADC noise is quiet high +vRefA directly tied to +3v3. The odd thing is a good part of the sample noise was coming from +5 feeding +3v3 LDO assume the MCU internal 2v0 LDO.
The launch pad…
All very good advice yet LP at this time ADC channels are open inputs simulating analog rising steps driven by residual AXi input gate E charging (Csh), (Rsw) internal resistor and capacitor. Must point out none of that added motor discussion has to do…
