VGA pinout (newb)

Joel Boyer

Forgive my ignorance...I'm looking for a pinout for the dsub15 connector to my prop chip. I found one on the forums before, but i can't seem to locate it anymore. I know i have to use base pin 16, but i don't know which pins on the prop chip correspond to the pins on the connector. please help! Thanks in advance.

Also, you can choose any pins you want, you just have to change it in code.

Not quite.· Because of the way VCFG works, the VGA port pins need to be on 8 pin boundaries (e.g. pins 0-7 or pins 8-15 . . .).

Sorry, I meant that you change the base pin. Oops.

Thanks for catching that.

Choosing any pin [noparse][[/noparse]group] you want may be a bit troublesome as the majority of code is already configured for the 3rd group. That's the way the Demo Board and the Proto Board are set up.
