4.2 inch BWY display, problem with busy state

Open MorganMLGman opened this issue 5 years ago • 0 comments

Hi, I have a problem with my 4.2 inch BWY display. I wrote simple function void waitWhileBusy(){ while(digitalRead(BUSY_PIN) == 0) delay(1); }

and it's not working. When I check with meter busy pin when display is refreshing only goes to around 1.9 - 2.1V and not 0V. Do you have any idea what may I have done wrong or it's problem with my display?
