VGA FPGA

 

Based on http://fpga4fun.com/PongGame.html

767 was the value checked for at 25Mhz. This is a count of 768.

I doubled it to 1535. and added one to all references to Counter X.

I am confused on these values. References I’m finding say to shoot for 31.5kHz but this works out to 32.5khz?

50e6/31.46875e3 gives 1588.87785501. Ok. That works too. I guess the monitor is just flexible.

 

 

 

 

I got an error for can’t use pin 101 which is V sync

This helped

Need to disable nCEO which is using that pin

 

Alright. It appears to work. That is a good start.
