So, I'm trying to hook up my DOGM163 lcd display to my atmega168 in 4bit mode, but so far I have been unsuccessful. I followed the instructions on how to connect the two from this thread: http://embdev.net/topic/126291 I get no errors on compilation, but the display also stays blank when I run the program. My power supply is 5V and I have corrected for this by not having the capacitors shown in the circuit diagram. Also, my display is brand new, and I have just not gotten it to work yet. I'm fairly new to microcontrollers, but I have double and triple checked that I have connected everything correctly, and also I am using the D ports like the guy in the other thread. Thanks in advance for any help.
