    M032 emWin 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. To overcome this issue, the tslib supports calibration function, and the calibration parameter is stored ether in APROM.
