HI Check for a short between pin 11 of the 'hc374 and +5V. Pin 11 is supposed to be connected to pin 9 of the 'hc138. It is the select line for the 8 flip-flops in the 374. If you have a logic probe, check either of these pins. They should be (...) (29 years ago, 15-Jul-96, to lugnet.robotics.handyboard)

I'm using a hall effect sensor as a shaft encoder. 8 magnets have been placed on a wheel of my bot, such that they turn the sensor on and off as they pass by. I have written a small program to test the encoder, which makes the robot go forward 10 (...) (29 years ago, 15-Jul-96, to lugnet.robotics.handyboard)

Dirk, Without actually seeing your icb function, it would be hard to determine exactly what is going on. But here are some guesses: 1) When you are modifying control registers in MC, make sure that you use bit commands so that you don't set or erase (...)
