Hi everyone,

I was trying to interface my custom board with integrated bt815 to a capacitive touch display ph480272t009-iaf01.
However I found out that i2c seems to not work. I can't make it read one touch.
i2c st1633 address is 0x55 and the only way to read something from it ( 0 or 255) is setting the "supress 300ms" bit in REG_TOUCH_CONFIG.

 REG_TOUCH_CONFIG= 0x550 | 0x4

I would really appreciate if anyone can help me since we already manufactured many boards.

Thanks in advance.
