Hi
I am newby to LMP90080...
I have developed a PIC interfacing LMP90080 and i am able to communicate to the device
I am trying to read analog voltage on CH0 (single ended input - not differential).
The device is configured as follows:
- run from internal clock: CLK_EXT_DET=1 CLK_SEL=0
- Excluded buffer from signal path on channel 0: CH0_CONFIG BUF_EN = 1
Now I poll for ADC_DONE to be 0xFF and read ADC_OUTH and ADC_OUTL registers.
I am getting all the time the same value although i change a Vin voltage applied to CH0
The question is which steps in config I am missing? Probably some basic steps...but from DS it is unclear to me
Thanks in advance
