I followed the AD5292 datasheet and also the review from the CCS forum page linked above.
I connected the AD5292 to a Raspberry Pi 4 and ran a simple Python script to test the wiper,
but the wiper does not move anymore.
CCS :: View topic - For anyone who chooses to use the AD5292 in a new design...
Here are my current connections:
1. RESET: 10 kΩ pull‑up to 3.3 V and connected to GPIO17 (Raspberry Pi pin 11)
2. VSS: –15 V
3. A: 3.3 V
4. W: output measurement pin
5. B: GND
6. VDD: +15 V
7. EXT_CAP: 1 µF to GND
8. VLOGIC: 10 kΩ pull‑up to 3.3 V
9. GND
10. DIN: GPIO10 (MOSI) (pin 19)
11. SCLK: GPIO11 (SCLK) (pin 23)
12. SYNC: GPIO8 (CE0) (pin 25)
13. SDO: GPIO9 (MISO) (pin 21)
14. RDY: 10 kΩ pull‑up to 3.3 V and connected to GPIO27 (pin 13)
I also attached my Python test code.
Could someone help me figure out why the wiper is not moving?
Thank you in advance.
