Bootstrap with 'python' and check CIPD auth. Bootstrap scripts now use '#!/usr/bin/env python' instead of '#!/usr/bin/env python3' which should let them work on a wider variety of systems. Tested again with python 2 and made a couple minor changes for compatibility. Added check_auth() function to update.py. If it fails, it prints a useful error message and gets ABORT_PW_ENVSETUP=1 added to the environment. This is a cue to env_setup/setup.sh to not continue so the error is prominent on the terminal. (env_setup/setup.sh clears this variable so it won't persist into the next time env_setup/setup.sh is sourced.) Change-Id: Ib4a694178f1dce8971302914651feea3c727ea15
Pigweed is a collection of embedded-focused libraries, which we call "modules". These modules are designed for small-footprint MMU-less microcontrollers like the ST Micro STM32L452 or the Nordic NRF82832. The modules are designed to facilitate easy integration into existing codebases.
Pigweed is in the early stages of development.
$ git clone sso://pigweed.googlesource.com/pigweed/pigweed ~/pigweed $ cd ~/pigweed $ env_setup/cipd/cipd.py auth-login # Once per machine. $ . env_setup/setup.sh
If you're using Homebrew and you get an error saying module 'http.client' has no attribute 'HTTPSConnection' then your Homebrew Python was not set up to support SSL. Ensure it's installed with brew install openssl and then run brew uninstall python && brew install python. After that things should work.
The environment setup script will pull down the versions of tools necessary to build Pigweed and add them to your environment. You can then build with either GN or Bazel. You can also confirm you're getting the right versions of tools—they should be installed under env_setup/.
$ which gn ~/pigweed/env_setup/cipd/tools/gn $ gn gen out/host $ ninja -C out/host
$ which bazel ~/pigweed/env_setup/cipd/tools/bazel $ bazel test //...
And do the following to test on the STM32F429 Discovery board. (The bazel build does not yet support building for hardware.)
$ gn gen --args='pw_target_config = "//targets/stm32f429i-disc1/target_config.gni"' out/disco $ ninja -C out/disco $ pw test --root out/disco/ --runner stm32f429i_disc1_unit_test_runner -- --port /dev/ttyACM0
If any of this doesn't work please file a bug.
