Discussion - EVE / Re: PowerTip PH800480T013-IHC12 with HY4635: touch problem
« on: February 04, 2020, 02:34:11 PM »Hello,
Do you know which touch controllers your displays are using?
To perform the Hycon clock stretching fix for the BT81x, it is necessary to load a file to the touch engine for BT81x, please see below:
At least the 5" uses a EXC80h32 Controller, Manufacturer is eGalax. The 7" looks the same but I can't read something on the chip.
I did load this file but it didn't change anything. Is this file supposed to change the I2C Clock speed as well or only activate clock streching ?
