Hi,I am using STM32l072CZYx. I am generating the PWM using timer 3 channel 2. But PWM is getting trigger by SPI, PWM is resetting for some time. When I disabled the SPI, I am getting exact PWM. What will be the reason?What can be done to avoid such...

Hi,I wanted to generate PWM using timer on B-L072Z-LRWAN1 board for LED Dimming.I searched on the forum and web for this but I am unable to get any example for PWM on B-L072Z-LRWAN1 .Which LED I can use for this purpose?Can any one help me with this?

IS there any update?void MX_TIM3_Init(void) { __HAL_RCC_TIM3_CLK_ENABLE(); TIM_ClockConfigTypeDef sClockSourceConfig = {0}; htim3.Instance = TIM3; htim3.Init.Prescaler = 320; htim3.Init.CounterMode = TIM_COUNTERMODE_UP; htim3.Init...
