I use handy board and xc40 board(It has xc4010 FPGA chip) The problem is that they must communicate each other. But I don't know how I can make them communicate. In Q&A(at mit's handy board home page) it says that SPI pin can be used as digital (...) (26 years ago, 7-Dec-98, to lugnet.robotics.handyboard)

Shiva, When the Windows hddl.exe complains that it cannot open the port, it is usually due to another Windows programming using / holding that serial port. Try all the comm ports to see if hbdl.exe allows it to open one of them, then attach the (...) (26 years ago, 6-Dec-98, to lugnet.robotics.handyboard)

I would think so, assuming that you keep the data rate relatively low (IMHO, 9600 bps would probably be pushing it, 2400 may be better) --phil (...) (26 years ago, 6-Dec-98, to lugnet.robotics.handyboard)

I am using a rug warior pro whose brain is very similar to the Handyboard and would like to know if these VHF radio Data Modules could be set up between the computer serial port and the Rug Warrior brain to provide a radio link instead of the 4 wire (...)

Hi folks! I've found Terri Cherr's idea of using VHF data modules excellent, not only to exchange voice, but to communicate to a host computer also. The "robot" could send sensoring information to a computer (or even another robot) and receive (...) (26 years ago, 6-Dec-98, to lugnet.robotics.handyboard)

Another possible neat solution would be to use a pair of VHF radio Data modules at each end. These normally send digital data, but if you pulse width modulate / demodulate at each end then audio could be sent. There is a company that advertises in (...)

That will only allow one half of the conversation. I suppose you could run with two kits, one receive, one transmit, both tuned to different frequencies. Another suggestion might be one of the cordless, battery operated intercom system units. Most (...) (26 years ago, 4-Dec-98, to lugnet.robotics.handyboard)
