A simple C++17 class library for low level programming. Interfacing to hardware devices via MMIO registers. Interface code generated from CMSIS-SVD via Jinja templates. I recently read Real Time C++, by Christopher Kormanyos. It gives a good overview of C++ for small embedded devices and I’ve been meaning to try...

This post is about a common requirement in low level programming - accessing hardware devices via MMIO registers. CMSIS-SVD is an XML file format used by the Keil IDE and MCU on Eclipse to define a hardware device to the debugger. The XML file defines the registers, interrupts and CPU...
