Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
I'm looking for the appropriate MCU to include as a main processing unit in a DAC product I'm designing. The product uses an XMOS for USB Audio and is in need for a central CPU with a more approachable programming model. I came around choosing betwee...
Hello everyoneI'm trying to upgrade/update my firmware via DFU. USB device is succesfully connect to my PC, When I press Upgrade, interface not show any problem but actually my application area flash still FF. I can not program application area? Ayno...
Using CubeMX I generated a project that uses just the USB Device and CDC middleware. It builds without errors, however when plugged into Windows PC it fails to enumerate. The error shown is "A request for the USB BOS descriptor failed." I hope someon...
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...
