I'm working with STM32L475 and I'm using LPTIM to create a PWM signal. LSE clock is used (because I will use Stop mode), and period is set to 31 in ordet to generate 1kHz signal. PWM is working fine and dutycycle is modified according to the pulse value I set to the 'HAL_LPTIM_PWM_Start' function. Nevertheless, when I try to set PWM signal to 100% or 0%, the output signal looks similar to the one I have when dutycycle is set to 99% or 1%. Do you know why I get such behaviour?
