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 tried to use the USB Device CDC Standalone example to make my MCU (STM32F407iG) working as a USB TO Serial Converter Bridge like a PL2303TA Chip. But somehow the USB FS doesn't connect to my PC. What am i doing wrong do i need to change the cloc...
HI, I just bought STMF769i-eval and started with lwip examples from the FW . but there are not working, even i can't ping. then I read about Solder brigdes and de solder some of the brigdes and try again but still unable to ping. is that hardware pro...
I have an FreeRTOS example running on STM32F429I-DISCOVERY/NUCLEO-F429ZI, which has the STM32F429ZITx MCU inside. But I wish to port this to a new MCU (STM32F429VITx). How do I do it?The main difference between the two MCUs is:ZITx version has more ...
I'm using HAL library for stm32f4 (V1.7.1) and trying to understand how HAL_I2C_Master_Transmit works. This function transmits a master to slave packet on SDA line. In the stm32f4xx_hal_i2c.c code after sending slave address there is a loop (while(hi...
Is the cdc standalone example for asynchronous uart mode or synchronous mode?
We are currently developing a portable device with a STM32F4 display and so on. It is usually powered with non-rechargeable batteries (4x AA LR6). It consumes at least 140mA and max 450mA. As everyone has a micro usb cable and power plug, we thought ...
Hi,how can i program the BRR Register in the USB Device CDC Standalone example for STM32F4xx?The Example code uses UartHandle.Init.BaudRate = 9600;How can i directly access to USART_BRR Register?
This is the snippet of the code that is showing me the error. It has been written just above the while(1) function.Also, I have attached the whole code in the attachments. FATFS myFATFS; FIL myFILE; UINT testByte; if (f_mount(&myFATFS, SDPath, 1) == ...
How can I test this entire Boot loader receiving application software over SPI for STM32F207 X and Y version chip , and how to check if my IC is STM32F207 X and Y version .I am working with STM32F207 as making it as Slave SPI and using another Master...
Hi,I'm working in an audio project. We use stm32f407 like a USB audio device to get audio data from PC then send out by I2S module. We are using stm32f4 Discovery kit and STM32cubeMX. After generate code, i change nothing and flash to Kit; my PC ide...
