Good health to all!


The quarantine forced me to spend all my time at home, including free time, and although there are a lot of things to do at home, I skillfully shoved them to my son, and I decided to finally study the ClB development environment from JetBrains, especially since the 2020.1 release Support for the IAR toolchain appeared.


Everyone who is interested in a step-by-step guide and a bunch of pictures with a welk ...
