Hello everyone, I am working on a project to add a ping sensor and a MMA7341L 3-axis accelerometer for class and find that my pololu 3pi does not have enough pins. I have some at89c2051-24pu chips here and was wondering if they are compatible with the chip on the 3pi. I know they would have to connect through the serial port, would I be able to program both chips this way? If not, how can I program it, or is there a better chip to use? I am assuming I can attach the clock from the 3pi and use the second chip to control all the sensors. Am I wrong in my thinking? Is there anything anybody knows that could help? What we are trying to achieve is to have the bot avoid hitting an obstacle and return to its original path.
Thank you all for you time and advice in advance.
