official raspberry pi touchscreen registers

Thu Sep 20, 2018 7:02 pm

Hei,

I have question, does this screen have datasheet somewhere? I just need to know register values but I haven't found any info about that 🤔. Only one Windows IoT forum I found pace of code where I found display I2C address and register address for changing display brightness but that's it.

For the record, I use windows 10 IoT on my raspberry.

The TS interface is handled by the GPU, so we have never published the datasheet. There is a mailbox call to grab the data rom it though - you can see this usage in the Linux driver.
