This simple project gives an example of how to use CMake + libopencm3 for stm32 development with C++. A specific example is given for the stm32f765 cpu. The blink example comes from libopencm3's miniblink. The openocd tool is used for flashing with a stlink-v2.

• Install an arm-none-eabi toolchain and add to PATH (following here) -- tested with gcc-arm-none-eabi-10-2020-q4-major
• install openocd and setup udev rules if needed -- tested with 0.10.0

• Tested on VOXL Flight Core using a knock-off stlink-v2 programmer
• had to use reset_config none when setting up openocd to program this specific board --- make sure RESET pin is connected.
• After getting stlink-v2 programmer connected to voxl flight core (with separate power), run make blink-stlink-flash to use openocd to program the board.
