The SPI (synchronous peripheral interface) does not do normal RS-232 (aka "asynchronous serial") in hardware. you must write an assembly language driver to do the timing. at some point in january i plan to release a 1200 baud output driver. if (...)

I have seen these all over - they are simple 900Mhz wireless links for video/audio. I think Radio Shack sells a device like this, as do the two places Mike Ross mentioned, JDR (URL) and Supercircuits (URL)---...--- (...) (28 years ago, 3-Dec-96, to lugnet.robotics.handyboard)

(...) I put one on my project. Expect video dropouts from Rabbit type (i.e. 900 MHz) devices, when the robot goes behind trees, dense walls, and other areas. If you're using the video to drive the robot remotely, you'll have to back out of such (...) (28 years ago, 3-Dec-96, to lugnet.robotics.handyboard)

I have been using the Handyboard on an R/C vehicle platform with Hall Effect sensors as the wheel shaft encoders. I've succesfully used the encoders.c routine which requires hooking the Hall Effects to Digital Ports 7&8 for about six months now. The (...) (28 years ago, 2-Dec-96, to lugnet.robotics.handyboard)
