2022-12-14 03:22

Hi Goodix,

We use the Goodix GR5515IGND chip with I2C touchscreen.

The problem is that the SDA and SCl pins are are swapped?. Can you please tell me if it is possible to swap them in some way by FW/SDK/..(w/o hw changes)?

Thank you in advance! We are in the active development phase and it is very problematic to wait for the next revision of the hw at this stage...

Hi, sorry to hear that, but the pin mux is fixed and can't be wapped by FW/SDK.
