Hi When HAL_Delay goes into uart interrupt, the program stops. Is there a way to work it out? I tried to use NVIC, but I don't know how to set it up. Please advise. Thank you. Here is my uart interrupt service routine. void HAL_UART_RxCpltCallback(...

Hi, I'm giwon KIM in South Korea. I'm using NUCLEO-401RE board. In STM32F401RE datasheet and reference manual, It is said to be capable of operating at up to 30 MHz.So its conversion time was set by calculating (12+3) / 30 MHz = 500 nsec.I generated ...

Hello, I'm using STM32F030C8 and I have created 4 PWM waveforms.I want to create PWM and stop it after one cycle.I'm thinking of how to create PWM and stop directly after one cycle. Is there any other way? Thank you.

Hello I'm using STM32F030C8.I'm writing the code because I want to use the internal flash memory like rom.Is there a set number of times I can write in internal flash memory? If there is a related document, I would like to see it.Thank you.

Hi, I'm using NUCLEO-H753ZI Board. There was a mistake while conducting the experiment. After that, the red light on LED6 came on and the red light on LED6 came on again after disconnecting the cable. Looking at the User Manual, LED6 comes out as Ov...

I understand what you're saying. I'll have to approach it in a different way. Thank you.

ADCCLK is shown in the Datasheet like this.If I set APB2 to 60Mhz and clock divide to 2, is it correct that ADC operates at 30MHz?

HI,I modified my code and settings. /*** @brief ADC1 Initialization Function* @param None* @retval None */static void MX_ADC1_Init(void){ /* USER CODE BEGIN ADC1_Init 0 */ /* USER CODE END ADC1_Init 0 */ ADC_ChannelConfTypeDef sConfig = {0}; /* USER ...

I'm changing pwm mode and opm mode using external buttons.When entering opm mode, keep high level and generate pulse. I want to keep low level and generate pulse. void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { switch(GPIO_Pin) { case GPIO_PIN...
