Hello ,I passed the confirmation e-mail to our purchasing Dept. in order to purchase the board, and they confirmed the purchasing.but I get an e-mail today from st indicating that my seat is re allocated to another participant .What should I do to co...
Hello,As described in the reference manual of STM32F746, it was found that bidirectional communication using one data line (SDA signal) in the figure can be realized by performing half-duplex communication using the SPI function.Please tell me the s...
Hi,I want to interface 3-phase DC motor's hall sensor with STM32H74x MCU. I found a timer's hall sensor mode in a document but I don't have any example code to get start with it.Can anyone please provide a reference or pseudo code for it.Thanks in ad...
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) {...
