HI , am a beginner i am using the follwing code HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sine_table, 20); HAL_TIMEx_PWMN_Start(&htim1, TIM_CHANNEL_1); // Start the DMA with the 180-degree phase-shifted sine wave table on channel 2 HAL...

Hi What is the most efficient method in program logic to generate a sine wave using an H-bridge with an advanced timer?I am using TIM1 on an STM32 microcontroller, which has two channels (Channel 1 and Channel 2) and complementary outputs. For genera...

I'm encountering an issue with the update event triggering in STM32 TIM1. I have configured TIM1 to generate PWM signals and set the update event to Center-Aligned Mode 3. However, I've noticed that the update event occurs not only when the timer's c...

HAL_ADC_Start_IT(&hadc); HAL_ADC_Start_DMA(&hadc, ADC_RES, 160); Called HAL_ADC_Start_IT(&hadc);function firstly only for enable the interrupt HAL_ADC_Start_DMA(&hadc, ADC_RES, 160); and called it And worked as expected is there any problamatic situa...

Hi OkCan i update the ADC interuupt bit likewise as follows ADC1->CR |= ADC_CR_ADIE; or like low level access the concerned bit i am not good programmer sorry for the silly question ?

ADC data should save to array by using DMA HAL_ADC_Start_DMA().and it is working am able to see the data saved in array .But I need funtion to do whenever each adc samapled . so I required ADC interrupt .

Thanks to know that way . But i didnt get well I need as follows Am generating PWM using Via DMA array (TIM1 + update Event )am aslo trigger an ADC via the same TIM1 update event and saving to DMA array by using the following function HAL_ADC_Start...

Thanks for the reply .Yes I know the calculation but i tried to get the maximum value But it is 38 limited ,There is no document reagarding it that why I asked ?if we use 48 MHz we get as follows T = 1 / (48,000,000 Hz) T ≈ 20.83 nanoseconds with a ...
