Topic: Firmdata on Serial1, possible? (Read 709 times) previous topic - next topic

Hi there,

I'm almost sure Firmdata can only work on USB serial but I have to ask anyway: is there a possibility to make it work on virtual Serial1 (pin 0,1), for example on Leonardo or Micro?

Thanks, Eric

What do you have connected to pins 0 and 1? The PC is generally on the other end of the USB cable/Serial port.

The goal is not to use a USB port, but one of the PC's serial port. As Pin 0 and 1 have TTL levels, it would require an RS232 voltage driver, of course.

Got a golden oldie, eh?

Of course.

An oldie, nah! (well, mine is)  :-)
Yet, plain old serial works all the time, and it doesn't require a special driver, and the cable is cheap.
Note that the Arduino will be inside the computer. No DB9 connectors needed, just 3 wires.
If what we plan was an external device to be plugged/unplugged then I'd choose USB.
