I am waiting to receive the pololu programmer so I can duplicate the example on your website to see the Baby-O being programmed with Arduino blink LED.
For connecting the Avago 2904 display I will first install the example from the arduino post on Arduino and will use the following pin definitions: Baby-O, Arduino
Data in, DDD1, pin 1
RS, DDD2, pin 2
CLK, DDD4, pin 4
EN, DDD0, pin 0
Reset, DDB0, pin 8
As my boards are powered from an RC ESC at 5V I can use M1A and M1B to power the display, all display connections can then be found on one side of the Baby-O.
Here is the datasheet, that will keep you busy intil the mail arrives.
Question: In de Arduino example a function Serial.begin(9600); is called. Do you know whether this can be messed up by the Baby-O which is working on 20 Mhz and most of the Arduino stuff is at 16 Mhz?
