|
| I was wondering if anyone has used IR transmission in their programs and if so, do you have a bit of simple sample code i could take a look at and if you knew variable ranges or anything. Also..does anyone know a common household material that will (...) (27 years ago, 25-Mar-98, to lugnet.robotics.handyboard)

| I wrote a similar type scenario using a PIC (pre handyboard user)... The trick I found was not to rely on a single return, but multiple. That is, use a counter, to count the number of hits. Use 64 as a base number, count down for each hit, up for a (...) (27 years ago, 25-Mar-98, to lugnet.robotics.handyboard)

| Thanks All, With the help you provided I think PipeBot will be a success. It is about to go on it's first test sortie under the house with an umbilical and tether. The umbilical is tied to three of the digital inputs so I can take over control if (...) (27 years ago, 24-Mar-98, to lugnet.robotics.handyboard)

|
| I couldn't sleep so I thought I would make some use of my insomnia. Several people have asked if the HB's memory can be extended, and usually the answer is no, not if you want to run IC. I have been taking a break from my navigation systems, and (...) (27 years ago, 24-Mar-98, to lugnet.robotics.handyboard)

When you call the function ir_data( 0 ), it returns the last IR signal received, or zero if nothing has been received since the last time you called it. --Will (...)
