Discussion - EVE / Re: Can BT815 determine the Touch-Controller Type by itself?
« on: January 19, 2024, 02:09:28 PM »
Hello,
Thank you for your query.
Unfortunately the BT81x series cannot automatically detect which type of touch controller is connected.
The Goodix and FocalTech controllers utilise different I2CX addresses which must be configured via the REG_TOUCH_CONFIG register.

Thank you for your query.
I have a project where some displays are with goodix touch controller and some are with FocalTech touch controller.
Is it possible that the BT815 figures out which controller is used by itself?
