Hi everyone,

I m new Arm programming. I have been trying to make emWin app with LPC4357 Dev.Kits and TFT 7.0 which is Embedded Artists too. But I couldn't . In sample app. which given by Embedded Artist' and in LPC Open 2.10 have no emwin sample app. Do you have this sample app ?

I have run emwin app. with tft 7.0 , but touch screen is wrong. it needs to calibration. Can I calibrate touch screen on emWin ? Should I change only LCDConf.c?
TFT 800x480 7.0 . I have attached LCDConf.c file.
