Hi everybody,
I have few questions about the PWM configuration pin on the periph_config.h [1] on STM32L152RE. The pwm.c file is already done, we were based on pwm.c stm32f3 discovery file. We also used this two manuals [2] [3].
What is the link between PWM_0_PIN_CH0 and PWM_0_PIN_AF ? Does PWM_0_PIN_AF refer to the GPIO_AFRL_AFRLX (X € [0…7] ) or the GPIO_AFRH_AFRHX (X € [8…15] ) in stm32l1xx.h ?

Kind regards
Tara.
