I'm using this PWM setup:
TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStruct; TIM_OCInitTypeDef TIM_OCInitStruct; GPIO_InitTypeDef GPIO_InitStruct; /* Step 1: Initialize TIM2 for PWM */ RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE); TIM_TimeBaseInitStruct.TIM_Prescaler = 0; TIM_TimeBaseInitStruct.TIM_Period = 255-1; TIM2->CCR1 = 128; TIM_TimeBaseInitStruct.TIM_ClockDivision = TIM_CKD_DIV1; TIM_TimeBaseInitStruct.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM2, &TIM_TimeBaseInitStruct); TIM_Cmd(TIM2, ENABLE); // Step 2: Initialize PWM TIM_OCInitStruct.TIM_OCMode = TIM_OCMode_PWM1; TIM_OCInitStruct.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStruct.TIM_OCPolarity = TIM_OCPolarity_High; TIM_OCInitStruct.TIM_Pulse = 0; TIM_OC1Init(TIM2, &TIM_OCInitStruct); TIM_OC1PreloadConfig(TIM2, TIM_OCPreload_Enable); /* Step 5: Initialize GPIOA (PA0) for PWM output */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE); GPIO_InitStruct.GPIO_Pin = GPIO_Pin_0; GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF_PP; GPIO_InitStruct.GPIO_Speed = GPIO_Speed_2MHz; GPIO_Init(GPIOA, &GPIO_InitStruct);
What frequency is set?
The resolution has to be 8 bits.0 to 255.If I want to increase the PWM frequency and keep the resolution, how should I proceed?
STM32F103.
