/** @defgroup Encoder Driver / Incremental encoder
* @brief Driver for an incremental encoder.
*
* This driver uses a timer of the STM32, configured as a quadrature decoder.
*
* Call enc_Init() first in the initialization code. Then, call enc_GetPosition() to
* get the decoded value.
* The output value is the paddle position in degrees, taking the reduction
* ratio into account.
