• Hi:
  I have a question.
  I got a hdim interface touchscreen. I know I can plug the touchscreen to the board, it will must be display something. But if I want
  to use the touch function, how can I do? because According to the product presentation of a20-olinuxino-mirco,the board use touch LCD with 4.3", 7.0", 10.1" LCD modules from Olimex. The olimex lcd modules is RGB interface use 40 pin connector.
  
  Maybe a20-olinuxino-mirco does not work touch functin on hdmi touchscreen?
  
  If it can be work , please give me some hint.
  
  Thanks a lot!
