- * HAL_TIM_Encoder_MspInit()
- * Overrides the __weak function stub in stm32f1xx_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.
- *
- * http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00161566.pdf
- * Table 5 has GPIO alternate function pinout mappings.
- *
- * TIM1_CH1: default PA_8, remap PE_9
- * TIM1_CH2: default PA_9, remap PE_11
- *
- * TIM2_CH1: default PA_0 
- * TIM2_CH2: default PA_1, remap PB_3
- *
- * TIM3_CH1: default PA_6, remap PB_4, PC_6
- * TIM3_CH2: default PA_7, remap PB_5, PC_7
- *
- * TIM4_CH1: default PB_6, remap PD_12
- * TIM4_CH2: default PB_7, remap PD_13
- *
- * NB one of these timers will be the employed by mbed as systick, unavailable as encoder.
