Blinky++ is a C project that spans multiple platforms with a simple aim, to create the generic LED blinky but also to measure the toggle performance of each platform.

Blinky++ depends on various compilers, here are a few with pages on this site.

For STM32 install gcc-arm and for STM8 install sdcc

Another compiler is avr-gcc for the AVR targets, this is available on most systems.

For the STM32 targets, [:tools:libopencm3|OpenCM3]] must also be installed.

Fetch the blinky++ application and build it for all platforms.

hg clone http://hg.kewl.org/pub/blinky++
