Title: Trouble using Serial Monitor with Arduino and DigiStump PRO
Post by: rmetzner49 on November 13, 2017, 05:05:37 pm

Having trouble understanding what's missing. My sketch appears to upload just fine, but since the DigiStump USB driver is a "stripped down" version, the "Port" selector is grayed out, the Serial Monitor doesn't work because Arduino never finds the port.


What else do I need to install to allow Serial.println("Hello World); ?

Thanks.

It's greyed out because the Digispark doesn't have USB to Serial converter hardware, so doesn't present as a COM port.

If you want to pursue that, you can give DigiCDC (link (https://digistump.com/wiki/digispark/tutorials/digicdc)) a go, but you're probably much better off getting a USB to serial adapter (i.e. CH340 are cheap on eBay and work well, FTDI are good but cheap ones are clones that can cause problems), and wiring it onto the GND, TX and RX pins on the Digispark, and using the hardware serial stuff.

I have a problem like you. I would like to know how to fix it. I really want to know.
