Hello,
I want to read a register or set voltage on the EVAL-5754REBZ via the J8 Interface (with a Pi Pico). No matter what I test, I get no response from sdo.
I tried the no os driver but the data written did not match the described output in the data sheet of the ad5754.
Setup
- Internal Reference: LK1 out
- Digital power supply: LK6 position A (USB cable)
- Controlled via external source (J8): LK position B
- LK12 out
- LK9 position A
- bin/2scomp & ldac: gnd
- clr: GPIO from Pico PI -> High
- AVDD: 5V
-AVSS: Not connected
-GND: Connected from GND from Pico Pi
The output of the pico pi looks ok.
I am attaching an image that shows the readback example from the ad5754 datasheet.
Thanks for your help.
