LowMEM WS2812b library ( WS2812B_STM32F103 )

This is a memory and CPU efficient implementation of WS2812B library for STM32F1xx processors.

STM32F103 Benchmark

• 10 paralel WS2812B outputs @ 72 MHz
• 16 paralel WS2812B outputs @ 128 MHz (overlocked)

See my other repositories for L0, F3 and F4 port where the library and implementation is explained in details.

You have to compile it with -Og or at least -O1 optimizations to take advantage of it.

This version/port was created in Eclipse IDE, but you can simply call make in the Debug folder and compile the sources.

The only board with STM32F103 I had was on the ST-link Discovery debugger, so I reflashed the debugger and set the WS2812b outputs on PA2 and PA3.
