For the last year I have been using the SerLCD 2.5 white on black connected to an Arduino uno. Been working just great! Today, I unplugged the Arduino/SerLCD project. When I reconnected to power, the Arduino and my code seems to work as expected (based on the attached LED and valve). However, the SerLCD turns on with all character dots illuminated for a brief moment and then turns black. Not even the splash screen appears. Verified that +5 and ground are connected with both a scope and DVM. Verified serial data at the LCD via oscilloscope. Is it possible that the setup in the LCD eeprom or the its firmware has become corrupted? If so, what is the best way to recover?
Also, the documentation mentions sending control characters such as <control>m to the serLCD. How to you send a control m from the Arduino?
Thanks in advance.
