If you want more information on any of Rich's projects you can give him a call at (303) 892-9352. Or, you can email him at richard at brouhaha.com (change the at to an '@'). But you're more likely to get his attention with a phone call.
Don't send me email about these, as I don't know anything about them. Talk to Rich.
The TW-523 module isn't adequate for this purpose. While it allows you to receive some of the control codes, it hides others.
It uses a 2 line by 24 character LCD display. The programmable characters of the LCD module are used to create vertical bar graphs.
Jim designed a programmer for the PIC16C84 that connects to a PC parallel port. It is more complicated than David Tait's programmer, but meets Microchip's requirements for voltage control for production programming. It also is designed to be a bit more robust with regard to preventing rogue software from damaging parts.
Jim is also doing some stuff with PICs and flux gate magnetometers.
Currently Gary has interfaced the PIC directly to the pause button of a VCR, but it could be done by IR or a wired control input (for instance using code from my Remote control for Sony A/V equipment project.
