Hi, thanks for your reply ... Why don't I use the encoder0_counts variable ? I want to create a multi-tasked environment with seperate processes for each wheel to calculate wheel speeds. The same code will be used to calculate speed for 4 wheels. (...) (27 years ago, 15-Mar-98, to lugnet.robotics.handyboard)

(...) If I am understanding you right... I haven't looked at the encoder routines yet, but I am assuming encoder0_counts is global. Why not, just omit the pointer count from the _encoder struct and just use the global, since you already have it? (...) (27 years ago, 15-Mar-98, to lugnet.robotics.handyboard)

Howdy all, I finally attached an infrared reflectance sensor to my handyboard and it works! With my non-existent electronic experiences I managed to solder a resistance (330 ohms) to a three-legged sensor similar to the four-legged variant mentioned (...)

I recently got a handy board and I want to use the infrared signal to keep it from hitting a wall. How would I do this and how can I get a touch switch and get it to work. Chris Frost forgetful@lisco.net (27 years ago, 15-Mar-98, to lugnet.robotics.handyboard)
