Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi,I'm using a SMT32H562ZGT6 uC with RTC pheripheral enabled and clock source from LSE. But HAL_RTC_Init() function returns HAL_TIMEOUT. Investigating I found the method RTC_EnterInitMode returns HAL_TIMEOUT.Clock configuration is performed before ca...
This is to document various uses of delays like HAL_Delay() in STM32 code. I have found 2 decent uses 1. Put at the start of /* USER CODE BEGIN 2 */ to stop the code from executing when we are reprogramming the board. 2. Put at the start of /* USE...
Hello Saket_Om, Now is better :). Next challenge is how to convert it for my target. I am using STM32u585Qii3. It seems there is no straight way in STM32Cube to migrate between controllers with different packages. Split from the thread below. (new ...
I have an SPI slave running on STM32L4 in DMA mode. Here is the basic structure (simplified for this posting): #define NSS (HAL_GPIO_ReadPin( SPI3_NSS_GPIO_Port, SPI3_NSS_Pin )) #define BUFFERSIZE 32 uint8_t SpiTxBuffer[BUFFERSIZE], SpiRxBuffer[BU...
I'm relatively new to STM32 and it's my first time working with DMA so this will probably be a very basic question.I'm using STM32G474 and I want to have 3 channels of advanced timer TIM8 working in "PWM generation CHx CHxN" mode. At a later stage I'...
I want to use the standalone CRC module to offload calculations AND transfers from CPU - using purely DMA memory transfers - is this possible on the STM32G474RE?
Hello @Community, I am working on the STM32F746NG board. In my application, I want to communicate with a PLC using the EtherNet/IP communication protocol to exchange real-time data. The problem I am facing is that my board does not respond to ping wh...
Hello,I need to communicate with a component whose configuration register expects a 9-bit value. However, my current SPI setup sends data in 8-bit chunks.In this case, what would be the correct approach? Should I send two bytes back-to-back? Or would...
Hi，I would like to in-live upgrade firmware of STM32F407 through USART1, that means in-application program(IAP) . If I remember right, there need a trigger signal from key meanwhile NRST is low.My question is that the Key signal could be connected t...
Hi everyone!I'm having trouble in measuring the VBAT through ADC. I'm using 3.3V on aNUCLEO_476 board to connect to VBAT and when I measure VBAT through ADC,I cannot obtain the value of the VBATHere's my code:void MX_ADC1_Init(void) { /* USER CODE...
