can someone please post some example code of how to read the state of a pushbutton connected to one of the expansion board inputs i wish to use it to stop a motor routine also can anyone recommend a good cheap stepper controller for use with the (...)

Hi I've tried to use the overflow flag to measure distances greater than 2.7m with the polaroid sonar. I've added the following line to the sonar_init(): bit_clear(0x1024,0x80); /* clear TOI, no Timer Overflow Interrupt */ I think the overflow flag (...)

(...) Hello Richard I think you should use a Gray code (consecutive decimal numbers are represented by binary expressions that differ in the state of one, and only one, one bit. Synonym: reflected or mirrored code). Its very simple for two bits: 00 (...) (24 years ago, 22-Nov-00, to lugnet.robotics.handyboard)

(the "encoders.c" functions seem to only count regardless of (...) (24 years ago, 21-Nov-00, to lugnet.robotics.handyboard)

A simple experiment I was doing earlier today showing the effects of delay between multiple pings of the sonar (to let echos die down, etc): (URL) a by-product, it has some kind of neat pictures showing the accuracy and such of the sonar, if you're (...)

I connect a motor to a motor output on my handyboard and it works fine. I start running the program found here: (URL) program continuously collects data from a GP2D02 sensor.
