Touch screen update

Today I’ve been reviewing the relevant documentation about the touch screen panel mounted on the 2.8 inch ILI display I intend to use for future projects. I think it’s all pretty much straightforward to integrate in my framework, including a 3-point calibration sequence to perform at start-up, that would ensure a more accurate measurement of the pen position on the panel.

Before bed time I got the part designed in an Eagle library, ready for integration in PCB designs as per below.

I’ve also had an idea for a new unrelated project. I am not too sure I will be in a position to develop it any time soon as it would involve some additional Android development to the one I already did for the Bluetooth module integration.
