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 use CDC to transmit data to computer .I want to transmit big array to the computer using CDC_Transmit_FSwhat is the maximum buffer length that support this function ?this is my code:CDC_Transmit_FS((uint8_t *)buffer,(uint16_t)73728);but some am...
There was a change in the HAL_PCDEx_BCD_Callback() function defined in usb_device.c that, by default, results in the code not handling the PCD_BCD_DISCOVERY_COMPLETED notification.The switch statement for processing the state changes in the new user ...
Im trying to send udp packets back and forth using a Nucleo F429zi board. As I debug the program, I get 0 for all the other errors, but for udp_sendto() I get a -4. I found that this error code corresponds to ERR_RTE, operation in progress error, but...
I implement a SPI slave protocol on a STM32F0 board.After the master as transferred a command to the slave, it polls in regular intervals by reading one byte off the slave until the slave sends a start byte of value 0xFF.in the attached screenshot, t...
I can't find an svd file for the STM32F415 https://www.st.com/resource/en/svd/stm32f4_svd.zip does not contain a svd file for the STM32F415 series is one of the contained ones 100% compatible? STM32F401.svd* STM32F405.svd* STM32F407.svd* STM32F41...
I am currently using a STM32F105 MCU configured to USB Device_Only mode by STM32CubeMX, including middlewares for communication device class (VCP).Since I had to use the PA9 pin as an alternate function (USART1_TX), I've planed to use another GPIO fo...
I want to make a streaming from MCU to PC over USB and write as a binary file. Now I have some real problems with USB speed. I tried to measure it andwhile (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ if ((dmaFlag != 0))...
In a new CubeMX project it is confusing when there is an interrupt routine or a callback but it is never called . It takes also time to find out who should call who and when. And please document in the function comment who and when that interrupt rou...
im using STM32F030R8T6 (nucleo F030R8 board)i tried to enable SPI2 peripheral clock, but i cant find any line in stm32f0xx_hal_rcc.h to enable spi2 clock,but there is macro for SPI1__HAL_RCC_SPI1_CLK_ENABLE()only few marcos for RCC_APB1ENR present in...
Hi everyone, I'm developing an HMI with STM32F446. it has 800x480 display as well as a stack for communicating the devices with the CAN. Also, this stack must be updated in 4 milliseconds. Now also needing mp3 player and radio. For radio, a IC can be...
