Hi,

Cool project, it would be handy to have the ISIS files too to simulate?

Thanks!

c'mon Wilskey, at least take your time and draw your schematic,  xpress embedo did a good job programming the firmware and pc soft...  btw i noticed the firmware is quite different from the one wrote by zuisti ...

Hi Tuco,
Yes, I can draw it myself, but it would "complete" the package and it would simulate "out-of-the-box", and since he has already drawn it, it seems pointless redrawing it, no?

I knew it was silly when you said "Humble opinion", it should be humble, indeed!
He better go with HID device; very easy to set up on both sides, I am sure it is better than CDC crap

What about replacing any 232 transceiver chip with a UART-> USB (FTDI et al) chip, saves faffing around with the microchip CDC /  HID stuff.
