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...
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...
I am working with the STM32F760I-EVAL board and caching (SCB_EnableICache() and SCB_EnableDCache() are called) and MPU (MPU_Config() is called) are enabled. I am using DMA with SPI and if I transmit data, HAL_SPI_Transmit_DMA, I need to call SCB_Clea...
I did interfaced STM32l151 with ENC424J600 using SPI , But know i don't understand how to make buff of data to send over ethernet .I did tried some stuff but all says incorrect sequence or frame, sometimes it shows LLC .I am stucked in here please he...
I am trying to figure out the details of how to jump to the internal bootloader on STM32L475. The following code works just fine on the STM32F405, but similar (updating the address obviously, which is actually the same) will not work on the L475.ldr ...
