    M480 emWin The project structure is shown in the following figure. The project contains two targets:  emWin_SimpleDemo: stores touch screen calibration parameters in APROM;  emWin_SimpleDemo_SD: stores touch screen calibration parameters in a SD card. The Libraries group contains low level driver and system startup code. The emWin group ®...

    M480 emWin The following figure shows the application halts in main() function after starting a debug session. 3.6 Touch Screen To support resistive touch screen, use ADC to convert the voltage of X axis and Y axis, and then use the open source tslib to map the ADC conversion result into the coordination. The conversion result can be affected by power noise, mechanical misalignment, etc.
  • Page 11 M480 emWin In the emWin_SimpleDemo_SD, a preprocessor symbol __USE_SD__ is defined to build the sample and use a SD card to store the calibration parameter as shown below. The touch resolution and the APROM offset store calibration parameters in the M48XTouchPanel.h.

    M480 emWin 5 Change Display Panel 5.1 emWin Display Configuration emWin declares display panel resolution LCDConf.c under ThirdParty\emWin\Config\ directory. The resolution is different from the touch panel resolution defined in the M48XTouchPanel.h. This is because the panel is a portrait display and data is swapped before output for a landscape view by LCD driver IC.
