spiderkiller 0:534dccd9b32a 3 * HAL_TIM_Encoder_MspInit()
spiderkiller 0:534dccd9b32a 4 * Overrides the __weak function stub in stm32f1xx_hal_tim.h
spiderkiller 0:534dccd9b32a 5 *
spiderkiller 0:534dccd9b32a 6 * Edit the below for your preferred pin wiring & pullup/down
spiderkiller 0:534dccd9b32a 7 * I have encoder common at 3V3, using GPIO_PULLDOWN on inputs.
spiderkiller 0:534dccd9b32a 8 * Encoder A&B outputs connected directly to GPIOs.

spiderkiller 0:534dccd9b32a 11 * Table 5 has GPIO alternate function pinout mappings.
spiderkiller 0:534dccd9b32a 12 *
spiderkiller 0:534dccd9b32a 13 * TIM1_CH1: default PA_8, remap PE_9
spiderkiller 0:534dccd9b32a 14 * TIM1_CH2: default PA_9, remap PE_11
spiderkiller 0:534dccd9b32a 15 *
spiderkiller 0:534dccd9b32a 16 * TIM2_CH1: default PA_0
spiderkiller 0:534dccd9b32a 17 * TIM2_CH2: default PA_1, remap PB_3
spiderkiller 0:534dccd9b32a 18 *
spiderkiller 0:534dccd9b32a 19 * TIM3_CH1: default PA_6, remap PB_4, PC_6
spiderkiller 0:534dccd9b32a 20 * TIM3_CH2: default PA_7, remap PB_5, PC_7
spiderkiller 0:534dccd9b32a 21 *
spiderkiller 0:534dccd9b32a 22 * TIM4_CH1: default PB_6, remap PD_12
spiderkiller 0:534dccd9b32a 23 * TIM4_CH2: default PB_7, remap PD_13
spiderkiller 0:534dccd9b32a 24 *
spiderkiller 0:534dccd9b32a 25 * NB one of these timers will be the employed by mbed as systick, unavailable as encoder.
