Hi, Ti engineer:
My current project plan is ds90ub941 (port0 is enabled) -> ds90ub948 -> dual lvds screen (including i2c touch screen)
How to configure to detect the touch screen connected to ds90ub948? I tried to configure the 0x07 and 0x08 registers of 941, and also configured the 0x08 and 0x10 registers of 948, using
i2cdetect -y 17 is not detected.
In addition, I want to confirm that the RST and INT pins of the touch screen should be connected to those pins of ds90ub948.
The RST and INT pins of my touch screen are connected to gpio0 and gpio1 of ds90ub948, right?
Hi Tao,
Are you trying to communicate your touch-screen display from 941? If yes, did you enable the I2C pass-through on register 0x03?

Hi
thank you, I thought I did not successfully submit a question?
Now I refer to the register manual configuration, it can be used normally now。
My configuration is correct, i2c has been connected, it is a hardware problem
Hi Tao,
Thank you for letting me know. I'm glad that you found the issue.
Aaron
