-- I NEED HELP PLEASE (updated 13 november 2006)

BUT, I'm not yet able to communicate with the processor using serial cable.

What I know:

Here come the questions:

  • just because you only have one comm port does not mean it is named "com1". I have only one comm port on my laptop, but it is named "com5". Have you tried all other comm port names (1...8)?
  • to send a new vems.hex without megaloader, perl ...path.../prog.pl vems.hex :COM3 Etw
  • but you should find out x for your COMx -port first, and find out if you get answer in either 19200,8n1 or 9600,8n1 for 'S' (capital S, see above). If megaloader does not work, prog.pl will likely not work either (and it needs serialport library).
  • I tried to send 'S' command in all the baud rate suggested, but I was unsuccessful. I even tried all other rates.

Hans: I don't know what was on the V3.1 board from the shop.. but try and see the 2, 3 and 4'th guides on this page: http://vems.hu/www.vems.co.uk/VEMS/
