And they paid 9 million dollars for those Eclipse plug-ins that together makes TrueStudio...
Visual Studio Code is open source, under MIT license. There was already a Cortex-Debug extension, also under MIT license. Together are working better than TrueStudio. Also, there is an Arduino extension that would have made MBED completely unnecessary. There are also extensions that offer colored syntax (apart from regular C/C++ language) for XML, Makefile, .ld and .s files. With excellent auto completion tools and the entire IDE is theme-able, not like Eclipse that has problems even there (especially with dark themes). All in one IDE. All free and fork-able. Cross-platform. And generating projects for VSCode is extremely easy (because even I can do it),
Laughable and extremely expensive decisions! But keep going, ST, and be proud!
