One simply types 'micronucleus CompiledFileName.hex' and you then plug in the Digispark after-the-fact! Micronucleus is polling for the connection so there is a 60 second window.

Micronucleus is a simpler tool than AVRDUDE, that is if one must be at the command line and upload the HEX anyway. The results is excellent (or, said properly, my results were excellent.)

So, with the bootloader of the Digispark a weebit smaller and the availability of a simple-to-use uploader program, micronucleus.exe (Windows,) I figured I should do a little Frankenstein doctoring and flash the Trinket hardware with the Digispark bootloader software. I have used several with the Trinket without modifications with perfect success. In addition to a pedigree heritage, there is a ready set of libraries available for the Digispark. Personally, I prefer the Trinket hardware over the Digispark, but the Digispark has a totally different ecosystem and is stackable, but for this article only the hardware design similarities will be exploited.Дigispark inherits most of it's personallity from the littlewire project, and having been around longer there is a significant following of users. The Trinket 5V and the Digispark share the same hardware design, right down to the LED being on PB1.
