- * HAL_TIM_Encoder_MspInit()
- * Overrides the __weak function stub in stm32f4xx_hal_tim.h
- *
- * Edit the below for your preferred pin wiring & pullup/down
- * I have encoder common at 3V3, using GPIO_PULLDOWN on inputs.
- * Encoder A&B outputs connected directly to GPIOs.

- * Table 15 has GPIOx AFx pinouts
