External Resources
Segger has created an evaluation software package with emFile, emWin, embOS, embOS/IP, emUSB Host, emUSB Device. Projects files for Keil MDK V4.22 and IAR EWARM v6.20/21 are supported.
The application auto detects which LCD (3.2 inch, 4.3 inch or 7 inch) that is connected and adjusts LCD parameters accordingly.
There is an update of one file (LCDConf.c - located under \Start\Setup). The update fixes an issue with the touch screen on the 7 inch LCD. Unzip this file at this location and rename it to LCDConf.c (overwriting the files supplied by Segger). Then recompile the Segger project.
