Other Parts Discussed in Thread: ADS127L11, ADS127L21
Tool/software:
I would like to evaluate a custom driver I have written for ADS127L21 on the basis of example code for ADS127L11. Some of the registers are significantly different, however. Could someone recommend a bare bones startup sequence that would work for L21? Would it be something like:
- Initialize SPI on controller device (SPI Mode 1, MSB first)
- Set Reset pin high
- Set Start pin high
- Toggle reset?
Would it be possible to then communicate with the ADC in 4 wire SPI mode to test reading/writing register values and data without CRC verificaiton, assuming we are satisfied with the default settings?
Is it possible to leave the PHI controller plugged in for power supply while we're communicating with the ADC evm board over the exposed SPI pins?
