Here is my source code: void CLOCK(void){ RCC_DeInit(); RCC_LSICmd(ENABLE); RCC_HSEConfig(RCC_HSE_ON); while(RCC_WaitForHSEStartUp()==ERROR); FLASH_PrefetchBufferCmd(FLASH_PrefetchBuffer_Enable); FLA...
Hello,I am building and electric field sensor. The driver signal for it is produced via DAC of the STM32F767zi microcontroller. The signal is 4 kHz and is generated at a sampling speed of 80 kHz via DMA and TIM6. As you can see from the picture the s...
I'm attempting to put my STM32L4xx into Standby mode, and then wake it up from GPIO or RTC. I'm not using any drivers. I've narrowed my problem down to the PWR peripheral clock, although I'm not sure if that is directly the cause. If PWR clock is on ...
Hello!I have STM32H743BI configure TIM4 to PWM GEnerationstatic void MX_TIM4_Init(void) { /* USER CODE BEGIN TIM4_Init 0 */ /* USER CODE END TIM4_Init 0 */ TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_OC_InitTypeDef sConfigOC = {0};...
I want to set a RTC alarm to trigger 1 hour from now but there doesn't seem to be a built-in function (using HAL) to add time. Of course 1 hour in the future is easy unless it happens to be almost midnight or worse almost midnight at the end of the ...
Hello guys, I previously asked the question about the UART interrupt but not get any reply. Currently am able to receive data from uart interrupt but not able to clear the buffer to get new data. please help. my code is void USART1_IRQHandler(void) {...
Hi, I am running an application on the STM32L562-DK. The performance of the application is lower than anticipated. I started investigating what could be causing the performance issues. I found some example projects that had hal function calls to e...
Hi All,I would like to install stm32 vcp dirver (version 1.5.0) silently, without asking any user interaction. I tried to start VCP_V1.5.0_Setup_W8_x64_64bits.exe with \S switch, in this case the installer is started, but it does not finish the proc....
Dear,These 2 functions are almost the same, the difference is the const DMA_FLAG_TCIFx and DMA_IT_TCIFx. However, when AND with the RESERVED_MASK (0x0F7D0F7D), it becomes the same. This also happens with EXTI_ClearFlag and EXTI_ClearITPendingBit.For...
