I have got project from china which uses mini2440 friendly arm
http://www.friendlyarm.net/products/mini2440
It do some specific tasks & works fine. I don;t have access to internal code.
1. After sometime touchscreen TFT misbehaves. I press at some point & it responds at other. Basically it needs calibration. Chinese vendor added password to tft calibration setting. I asked him but he further buys it from somewhere else & couldn't respond.
Can I calibrate TFT without affecting the main code inside it.
2. Can I add equivalent TFT with large size without affecting code & display.
