microsoft / microbit-touchdevelop

The glue that binds together TouchDevelop programs compiled to C++ and the micro:bit runtime system

Instructions.

• Install Yotta http://docs.yottabuild.org/#installing
• Install srecord; add it to your path

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

microbit-touchdevelop's Issues

TouchDevelop Library with `glue.cpp` embedded string resource build failed

Hello,

We're building a TouchDevelop library for our micro:bit accessories.

We found some guides and examples:

• BITVM extensions
• TCS 34725

We forked this repo and create our own - github: minodekit/td-minode. We develop our C++ glue layer based on it. We use yt build to ensure our code can be compiled correctly.

But When we copy to the glue.cpp string resource, The compiler took a long time and then we get an error. Then we do some test:

Test cases

Test 1:

1. Blank typescript without any ts function
2. simple glue.cpp: only an namespace with some simple enums
3. build failed

Test 2:

1. Blank typescript without any ts function
2. the same glue.cpp with the TCS 34725 example
3. build success

Test 3:

1. Blank typescript without any ts function
2. the same glue.cpp with the TCS 34725 example, but we changed the namespace name / or added some blank line to ensure generated a new SHA256 code.
3. build failed

Summarize

It seems the mbed cloud complier timeout?

Do you have any suggestions? Thanks.

By the way, We also create some PXT packages. They work well.

Best Regards,
Paul
