Hello,I have STM32G031 and I want to use PA8 pin (TIM1_CH1) to count pulses. My idea is to read number of counted pulses every 1 second and reset counter to 0. void TIM1_Init(void) { // Enable TIM1 clock RCC->APBENR2 |= RCC_APBENR2_TIM1EN; ...
I got 2 STM32F446VET7 MCU board and I am trying to communicate each other with LoRa E220-400T30S.I cannot found any usefull libraries so I am trying to write one.I can communicate with modules from UART and setting configuration parameters.Both E22 m...
I am trying to build a custom external loader for W25Q64 SPI. I am using the OCTOSPI1 using the follow pins.PE11OCTOSPI1_NCSPF6OCTOSPI1_IO3PF7OCTOSPI1_IO2PF8OCTOSPI1_IO0PF9OCTOSPI1_IO1PF10OCTOSPI1_CLKI have followed the stm32-external-loader/Demo_Pro...
Hello. I am working with a STM32H563IIKX, connected to an external Macronix MX30LF2G28AD NAND Flash chip. I have configured the FMC for NAND operation with what I think are correct parameters (this is completely new to me).I thought I'd try a very ...
Hi,I am having uart baudrate problems while HSI clock as uart source clock. No problem with PCLK as source with the same uart. In Cube IDE (V1.16.0) and F7 software package (V.17.2), I get different values for HSI_CALIBRATION:Ide gets as 0x10 while r...
Hello All,I have implemented a simple Web server using https://github.com/STMicroelectronics/STM32CubeF7/tree/master/Projects/STM32756G_EVAL/Applications/LwIP/LwIP_HTTP_Server_Socket_RTOS example. The Get method works fine but as soon as I use the PO...
Hello,We are using the MCU STM32H745 in our current design.We have faced the issue of working MCU properly and below are the problem,Case 1 : At power ON, some time the MCU work properly and sometime does not work properly, when it is not work proper...
This is both in RM0038 and RM0090 ADC chapter: the description of EOC status bit says, it indicates end of conversion (if EOCS=0) or end of sequence (if EOCS=1). However, in description of EOCS bit in CR2, as well as in numerous places in the narrati...
Our main hardware controllers use the STM32F303VCT6 microcontroller, which connects via SPI to a Rock PI S. Two daughter boards that use STM32F303 microcontrollers and SPI communication can be connected to the main master board. Although the system o...
Hello forum!I'm struggling to enable the burst feature described in the applicationnote from stm.I'm using cube IDE and I configured timer1 along with DMA1 to generate a specific waveform.Problem is, that after enabling the PWM via "HAL_TIM_PWM_START...
