User Guide

There are several examples provides, demo codes can be downloaded from #Demo codes

OpenX05R-C

This example is based on Waveshare Open405R-C.

  • Remove four LED jumpers, then insert the 2.8inch LCD to Open405R-C
  • Open the TouchPanel project, which is under the Open405R-C directory. Compile and download it to the development board
  • After downloading, press reset button of the OpenX05-C board, you can see that prompt information are printed on LCD:
Please use the stylus clock the cross on the screen. The cross will always move until the screen adjustment is completed.
  • You need to calibrate the touchscreen by touch pen following the prompt.
  • After calibrating, now you can try to draw on the touchscreen.

For more details, you can refer to the codes
