Assistive technology and accessibility • Spark Fun CAP1203 Capacitive Touch Slider not detected by Raspberry Pi

Hello Raspberry Pi community,

I'm trying to use a CAP1203 capacitive touch slider with my Raspberry Pi, but I'm encountering some issues. I was under the impression that these two should be compatible, but I'm not so sure now.

I've connected the CAP1203 to the Raspberry Pi as follows:
- VDD to 3.3V
- GND to Ground
- SDA to GPIO 2 (Pin 3)
- SCL to GPIO 3 (Pin 5)

Despite these connections, my Raspberry Pi doesn't seem to detect the sensor at any I2C address. I've run 'i2cdetect -y 1' to scan for devices, but the CAP1203 doesn't show up.

Has anyone successfully used a CAP1203 with a Raspberry Pi? If so, could you share your setup or any troubleshooting steps?

I'd appreciate any insights on:
1. Confirming if the CAP1203 is indeed compatible with Raspberry Pi
2. Potential reasons why the sensor isn't being detected
3. Additional steps I should take to diagnose the problem

Thank you in advance for your help!
```
