stm32-rotaryencoder

Simple library to interface with an incremental rotary encoder. Code may be suitable for porting to other libopencm3-compatible processors. Currently only GPIO bank A is supported.

Running the example

git clone https://git.drk.sc/Derecho/stm32-rotaryencoder.git
cd stm32-rotaryencoder
git submodule update --init
cd libopencm3 && make && cd ..
cd rotaryencoder && make

Having compiled the example you can now flash example.elf onto your microcontroller.

Divider

By default the rotary encoder will have to pulse twice in order for a callback to be triggered. This behaviour can be changed by defining ROTENC_DIV.
