IMX7DSABRESD EPD connector for touch panel

Question asked by Dennis Muhlestein on Jul 2, 2018

On the imx7d dev board, there is an EPD connector J13 that has i2c, interrupt, which seems like I could customize the device tree to talk to touch panels with a common FT5x16 6 pin interface.  Seems overkill though to buy a 120 pin connector and use 6 of them.  Is there a better way to bring those signals in and customize them during development?

 

I thought of using the I2C pins connected to the LCD 50 pin connector but there doesn't seem to be any pin available I could use as the interrupt.  Anyone have a better way to solve this or is using J13 the best way to go?
