The versatility of the STM32F103 makes it a staple across several commercial sectors:
You don’t vary voltage; you switch power on and off rapidly. The STM32F103’s timer in PWM mode: the stm32f103 arm microcontroller and embedded systems work
// Configure TIM2 for PWM, 1 kHz, 50% duty TIM2->PSC = 7200 - 1; // 72 MHz / 7200 = 10 kHz counter clock TIM2->ARR = 100 - 1; // 10 kHz / 100 = 100 Hz TIM2->CCR1 = 50; // 50% duty TIM2->CCMR1 |= (6 << 4); // PWM mode 1 TIM2->CCER |= (1 << 0); // Enable channel 1 output TIM2->CR1 |= (1 << 0); // Start timer The versatility of the STM32F103 makes it a
