I am a sucker for blinkie lights and I have enjoyed messing with the Minipov3 but I am not that well versed in programming. I have 2 questions:
1. Can I plug the pov directly to the serial port on the back of my laptop without a caple?
2. When I am in the command screen I receive an error message that ‘make’ is not a recognized command when I try to run "make minipov-program" . Any suggestions?

1. yes
2. install winavr (see the instructions)

Re: Error in Control BANNED
Ok, I thought that I had downloaded that but apparently I did not save it right. Thanks, it works great!
Now when I went to modify the display with new text only 5 LED's light up continuously. I used 120 lines for 3 words.
Could that be to much?

Re: Error in Control BANNED
I reloaded all original data and now I have no blinking lights.
Any thoughts?
Thank you for the trouble.

Re: Error in Control BANNED
For long messages like that, use the file large_image.hex (or something to that effect). It seems long messages like that need the other file.
