Plug in the Digispark ATtiny85 to initialise USB detection.<\/li><\/ol>\n\n\n\n1. Normal Arduino Compilation<\/h3>\n\n\n\n
To start programming simply hit the compile and upload button on the IDE. Once uploading starts you will see information about compilation in the status window. <\/p>\n\n\n\n
2. Micronucleus USB Detection and Upload<\/h3>\n\n\n\n
Once compilation is finished, simply plug in the Digispark Attiny85. Once it has been detected, you will see the device being programmed.<\/p>\n\n\n\n

Sample program:<\/h2>\n\n\n\n
My favourite and most useful example is from Jeff White – It wriggles a mouse… (Note that I had to insert a DigiMouse.begin(); in the Setup() function – without that it didn’t operate.)<\/p>\n\n\n\n
