I was playing around with a project last night and uploaded once without disconnecting my LCD-00813 from TX. It, naturally, did it garbling thing, but now my LCD is very dim. Even after several resets.
I include both Clear and Backlight full command in Setup.
//Clear: Serial.print(0xFE, BYTE); //command flag Serial.print(0x01, BYTE); //clear command. //Backlight full: Serial.print(0x7C, BYTE); //command flag for backlight stuff Serial.print(157, BYTE); //light level.
Many advanced thanks...
