Better Firmware with LLVM/Clang (2020)

The linked article is about using the LLVM/Clang toolchain to build firmware for ARM Cortex-M microcontrollers. It discusses the advantages of using LLVM/Clang over traditional toolchains, such as better optimization, improved diagnostics, and cross-platform compatibility. The article also provides a step-by-step guide on setting up the LLVM/Clang toolchain and compiling a sample project for an ARM Cortex-M4 microcontroller.
