TMDXEVM3358 I2C external peripheral

Other Parts Discussed in Thread: AM3358

I'd like to add a capacitive touchscreen controller to the AM3358 EVM running linux. Where can I connect the new peripheral board to the EVM?, I2C0 is in the LCD connector, but it is dificult to connect it there.

Once the physical connection is made, where can I find the best help to get it working in Linux?

Thank you in advance

Hi,

If you take a look at page 6 of the EVM LCD Board, there is a capacitive touchscreen controller on it, which isn't populated. Perhaps you could use some of the pads to connect your I2C.

Thank you Biser

What about Linux?, does Linux have a driver for this unpopulated driver in the EVM?, is the software driver integrated into the Linux SDK provided by TI?, is there an example or demo with a working capacitive touchscreen using this EVM?. I could take this as a basis to run my touchscreen driver board with my EVM.

Thank you in advance

I'm sorry, I only work on hardware issues on the forums. Perhaps someone else can comment on Linux?
