STM32L4定时器(TIMER)介绍
STM32L4实时时钟模块(RTC)介绍
I've setup the ADC Module in very simple mode: trigger by software and interrupt disabled. After the STM32Cube code, I enable the ADC Module with the following code: // ENABLE TIMER2 (SERVICE TIMER) LL_TIM_EnableIT_UPDATE(TIM2); LL_TIM_EnableCounter(TIM2); // Start Internal Regulator...

STM32L4数模转换模块(DAC)介绍
independent or simultaneous conversions • DMA capability for each channel • External triggers for conversion • Sample and hold low-power mode, with internal or external capacitor The DAC channels are triggered through the timer update outputs that are also connected to different DMA channels....
