Instructions.

Building with ARMCC

Install KEIL v4, do the license dance, figure things out, add to your path, etc.

yotta target bbc-microbit-classic-armcc
yotta login
yotta update
yotta build

Building with GCC

Patch module.json so that microbit-dal points to #experimental instead of #master.

yotta target bbc-microbit-classic-gcc
yotta login
yotta update
yotta build

Notes

Yotta doesn't clean up properly when: switching targets, switching branches in module.json. Always do yotta clean just to make sure. If you modified module.json, do yotta clean and yotta update. Also, blast away yotta_modules and yotta_target. Just to make sure.

The cloud compile service seems unhappy if the project doesn't compile (even though main.cpp is meant to be always replaced). So make sure that the projects compiles from a fresh checkout before pushing.

Using local version of DAL in Touch Develop

  • make sure Touch Develop is in TouchDevelop directory parallel to microbit-touchdevelop (for example, checkouts in /c/microbit-touchdevelop and /c/TouchDevelop
  • in TouchDevelop build as usual and run jake local; then head to http://localhost:4242/editor/local/mbit.html?lite=www.microbit.co.uk
  • in microbit-touchdevelop do the yotta dance with GCC as described above
  • in microbit-touchdevelop run either make run or ./run.sh
  • head to http://localhost:4242/editor/local/mbit.html?lite=www.microbit.co.uk&microbit=local
