Troubleshooting • Re: No touch on Adafruit 2.8" PiTFT Capacitive Touch screen

Thanks. I have not asked Adafruit yet. I guess that is next on the TODO list.

There do not seem to be I²C devices attached:

Code:

$ i2cdetect -y 1     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f00:                         -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --         

Just to be sure, both SPI and I2C are activated.

well ... Are you sure you have a display with cap touch? On this bus there is no device --> touch initialisation will have to fail.

Sorry, will leave it with you to check which I2C interface the touchcontroller - if any - is wired to.
