 | | Noise on the handy board
|
| Fred and handyboard experts, I have assembled two handyboards and I am now helping 15 other people build theirs at San Jose State University. I found a problem on the first two I build that I belive causes the Sharp GP2D02 not to work. The school (...) (27 years ago, 31-Jul-99, to lugnet.robotics.handyboard)

| (...) See the Polaroid sonar code (from the HB web site) for an example of how to measure timing signals on the TIC3 channel. You initialize with: bit_set( 0x1009, 0x30 ); /* ddrd */ bit_set( 0x1021, 1 ); /* at tctl2, */ bit_clear( 0x1021, 2 ); /* (...) (27 years ago, 30-Jul-99, to lugnet.robotics.handyboard)

| The clock speed on the Handy Board runs at 2 Mhz, which is plenty fast enough for most things IF you run the right code. IC, used in its C implementation is too slow to catch anything at 1 ms reliably. However, there are a few simple work arounds. (...) (27 years ago, 30-Jul-99, to lugnet.robotics.handyboard)

| I recently bought a Handy Board to use in acquiring time measurements varying by one millisecond. The Handy Board has a clock speed of 2kHz, therefore it should be able to measure down to one half millisecond. What I have found however is that the (...)
