Using the DEVKIT-S12ZVC with ADC0 setup from processor expert.
Problem:
getting ADC channel interference, channel after is skewed if one before moves.
also getting a very skewed temperature reading, 1.2V it should be 1.7-2.1 range based on the formula.
Setup:
10 bits resolution with a Conversion time of 57uS, with each sample taking 24ADC clocks cycles with 144.5us
I have 5 channels, each doing there own sample. All set to VRH_1, VRL_1 reference.
Channels
PAD11
PLO_HVI0_KWL0
BATS_VSUP_SENSE_VOLTAGE
CHIP_Temp_Sensor__or_Band_Gap
PAD10
Update**
The ADC seems to be working now, had to set
CPMUHTCTL_HTE = 1; //enable internal temp sensor
CPMUHTCTL_VSEL = 0; //select temp sensor and not bandgap
for the temperature sensor.
I think this also fixed the bleed for all channels other than the last conversion affecting the first conversion on the next read.
Still trying to figure out why I am getting bleed from the last conversion into the first conversion. The timing of all conversion is well under my start measurement call.
