Hello, I'm trying to use this SPI + I2C touchscreen which uses the FT6336U driver with my Raspberry Pi Zero 2W. I have already set up an overlay for the SPI part (for the image) and now I want to get my touch working. However, even though I have checked with a multimeter that all cables are connected correctly, i2cdetect -y 1 outputs a matrix full of empty (--) addresses. i2cdetect -y 2 is also empty.
The screen is connected to 3.3V, and I have checked the bus is working by shorting SCL to GND, which caused i2cdetect to run really slowly. Disabling my other overlay also doesn't solve it. And i2c is, of course, enabled.
