I just noticed that TWR-K70F120M does not support ADC based touch screen when using TWR-LCD-RGB board. All pins are not connected.
So next step is to enable CR Touch with some J-Pins. But I have not founded any example code which would show how to use CR Touch through I2C. Would you have any available? For example PEG Medical demo uses CR Touch so I have big hopes for this
Thank you for any help!
