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 everyone,i have an issue i can't connect to my com port using a composite device project.In the device manager everything is fine and the mcu is displaying as 2 devices but somehow i can't connect to the com port with any terminal program.I attach...
After initialisation thru latest CubeMx I2C using LL_Driver, I found few functions missing in stm32f4xx_ll_i2c.h, ie. (LL_I2C_HandleTransfer).I did refer few examples for some F0 device but could make out anything useful.Please provide me some soluti...
Dear all, I'm currently trying to work around the CAN Bus on the STM32F091CB uC, with StdPeriph_Lib_V1.5.0 Lib but the transmission is never successful (I have already programmed STM32F4 and STM32F7 boards with StdPeriph_Libs, without any problem).Th...
Hi I implemented a UVC Class with isocronous transfer. I'm using a STM32F745 mcu with RTOS ( 1000Hz Tickrate ) The USB Host lib is slightly modified to get correct URB messages after iso RX complete transfer.I receive Images in VGA/QVGA resolution an...
Posted on May 26, 2014 at 18:52 Hi everyone! I developed the USB Composite CDC+MSC. It worked right. Now, I want to disable a MSC and use CDC only. Do we have any way to do that (without re-connect the USB)? I tried to ignore the MSC...
Hi everyone, My project consist, in a bootloader with USB MSC, and the size of flash of this uC is 128k bytes, that is, there is only one sector.I had some problems with bootloader of this uC. If i program first time, all right, but if i program sec...
I have added the code written in HAL for I2C communication between I2C 2 of STM32L053R8T6 and LIs3dh accelerometer to receive whoami register. doesn't seem to be able to receive any data from the accelerometer.#include "stm32l0xx.h"#include "stm32l0x...
As title,all the startup script in the HAL V1.7.0 for F1XX chip contains the call to __libc_init_array , but the one for F105.Is there any particular reason or it is just a bug?thanks
I have an STM32F446 that has its firmware upgraded by another microcontroller through SPI-bus (please see AN4286, "SPI protocol used in the STM32 bootloader"). My application code starts at sector 4 (address 0x08010000) and I am able to successfully ...
Posted on June 21, 2017 at 15:04Hi,I've purchased the STEVAL-3DP001V1 board from ST, which is powered by a STM32F401VE. There is a jumper called boot which is wired as follow:So the pin BOOT0 is normally held high when the jumper is not fitted. BOOT...
