Thanks, but I can only find dial/toggle/tough at /uGFX/drivers. The toggle driver can do some simple job like a switch. However, I need a keyboard to type words. The problem is that how can I map the keys to different key-values, so that I can link the driver to uGFX. I try to find a example but I didn't find it, maybe I get the wrong directory. Anyway, could you please tell me where I can find it or provide a demo code?
Thank you.
