Dear all,
I want to use a HD44780 for a hobby circuit. So I have connected with my PIC MCU in a 4-wire interface and tried to communicate with it.
However I cannot display anything on the LCD. I will try to troubleshoot my design but I need to know something pretty important! I cannot understand whether the LCD has been initialized or not..(I have put some code in my program for initializing)
After connecting the power supply the LCD is not dark.. on the contrary it seems that the background light is on.. is this an indication that it is initialized? I have not used any LCD before.
