DS90UB941AS-Q1: Chip application problem

Part Number: DS90UB941AS-Q1

Tool/software:

May I ask a question, when using TI 941 948, do I have to connect the TP of the two screens directly or can I achieve it through 941 948?

If it is implemented through 941 948, please provide detailed instructions on how to operate it.

What should I pay attention to?

Hello Tonyx,

Can you clarify the question?

What do you mean by connecting TP?

TP stands for the touch panel on the screen. This means if I want to connect TP from both screens via 941 and 948, can I? What exactly should be done and what should be considered?

Hello,

Does your TP support I2C, SPI or what interface for touch screen?

Yes, this should be supported via 948 and 941, via the back channel. You just need to connect your TP to the right interface which will be connected to the 948, and on the other side, the same interface will be connected from the 941 to the SoC/controller.
