microbit

edge-node-manager compatible firmware for the micro:bit

Modify firmware

• Change line 12 in source/main.cpp to point to your dependant application UUID

Compile firmware

• Ensure you have the dependancies listed in the Dockerfile
• Set the target $ yt target bbc-microbit-classic-gcc
• Compile the firmware $ yt build

Flash firmware

• Compile the firmware
• Connect the micro:bit to your computer using the USB cable
• Drag 'n' drop the compiled firmware from /build/bbc-microbit-classic-gcc/source/micro-bit-combined.hex to the mounted micro:bit

Getting started

• Note: Take a look at the edge-node-manager if you havn't already done so
• Create a new dependant application called microbit from the Dependant Applications tab accessed from the side bar
• Add the dependent application resin remote to your local workspace using the useful shortcut in the dashboard UI, for example:

$ git remote add resin [email protected]:gh_josephroberts/microbit.git

• Retrive the dependent application UUID from the Resin dashboard, for example: If your dependant application URL is https://dashboard.resinstaging.io/apps/13829/devices the UUID is 14495
• Set the dependent application UUID on line 82 in application/application.go to point to your dependant application, for example: initApplication(14495, board.MICROBIT)
• Make sure you add, commit and push the change to the edge-node-manager application
• Add, commit and push the microbit application to your RPi3, for example:

$ git add src/main.c
$ git commit -m "Set the application UUID"
$ git push resin master

• Turn on your micro:bit dependent device within range of the RPi3 gateway device and watch it appear on the Resin dashboard
