I recieved an already assembled 3PI as a gift and I am using the WinAVR-20090313 library under AVR Studio 4 (ver 4.18) for programming. I have executed the BlinkLED test program and played around with simulation in the AVR Studio. I want to learn more about the architecture of the ATmega328P and the sensors and motors on the 3PI before I load up the basic line following program and start ‘tweaking’ it. Towards that end I would like to load up the 3pi-demo-program and play around with that code first. However I have not been able to locate it on the Pololu website or in the WinAVR library. Would someone please pass me a link to where I can get it?
On another note I notice that the green LED connected to PD7 is on dimly all the time - even when I have erased the program memory. When I modified the BlinkLED program to turn it on instead of the red LED I noticed that it wasn’t as bright as the red one. I don’t know if it was like this from out of the box or if it is something I have done. In fact it was so dim that I didn’t know it was on until someone else pointed it out to me. (My eyesight isn’t the best and I probably saw it, but thought it was a shiny solder pad reflecting the ceiling light.)
Sorry, for the long post and I appreciate any help you can give.
