I have been running Arduino IDE on a laptop for some time debugging my sketch involving a TFT LCD.
But out of the blue serial monitor has stopped working.
I tried restarting the laptop - same problem.
I tried ruuning an example sketch from Adafruit_TFTLCD - the sketch runs but no output in serial monitor despite the fact that I changed Serial.begin(...) in setup() to the baud rate I am using.
I tried running my sketch without serial monitor open and it works fine.
But as soon as I open serial monitor my sketch stops working an I get a white screen.
Has any body encountered this problem?
If so how do you fix it?
Re-install Arduino IDE?
