Question. Since the expansion board requires a new lib_hb.c and the smooth PWM routines require a different lib_hb.c and pcode_hb.s19, can we have both expansion board and smooth PWM together? John Schneekltoh (26 years ago, 3-Mar-99, to lugnet.robotics.handyboard)

Dear Casey Russell, When pcode is disabled, the handy boards stops treating the data received on the serial port,in the manner the pcode wants it to. The bytes it receives through the com2 port is then just plain data for it. It should know what to (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

I'm glad you mentioned the Nuts & Volts article, "Naked Data"! I've used the MING microdevices RF transmitter and receiver units with success! The 1200 bps isn't fast but great for small projects such as mobile robots. I used the MING RF units with (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

for RF communications, I recommend Linx Technologies (URL) They sell seperate transmitters, receivers, and antennas. For two-way communication, you would need two pairs, so the price is around $30 for a bidirectional link. They have speed ranges (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

The original IC and pcode was originally written on a Unix machine. There are scripts and a makefile that simplify the compile procedure. I use a Linux PC to modify the pcode all the time. If you have access to one, download the original pcode (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

There is an article in DDJ on the WOOKIE 68HC11 emulator in Mar 99... There are files in www.msoe.edu/eecs/ce.../resources including GNUs gcc C compiler with a back end for 68HC11.. I think that it is targeted for the rug warrior. You may need to (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)
