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...
HiI noticed on my STM32G071.. that the "LL_mDelay(1000)" function did not produce a steady 1000ms delay if I vary the HCLK frequency (code generated by CubeIDE)...I did not have this problem with other MCUs code generated, it worked out of the box (...
The function int32_t BSP_SD_Init(uint32_t Instance) (which I believe is the first thing to call to initialise access to the SD card on the STM32H747 Disco board) attempts to check if card detected on line 160. However the pin that is used as card det...
Posted on October 10, 2014 at 04:04Hi,Ideally, I'd like to have a firmware that has the following support: Cube-basedWorks in STM32F4Works as a dual-mode USB Device (not Host) in Audio Device Class, where these 2 endpoints are configured: (a) 1...
The eaxample of dfu mode stm32l152 not run !!!These are my step :I build and execute code via IAR on Nucle0l152 board with usb _CN1 cable .Then i dsconnected CN1 usb cable and i connected my USB cabel to PA11, PA12 , gnd and 5 v .Then I open Open...
I've got an audio codec chip with bidirectional i2s interface, but I can't find any examples or any other info on configuring bidirectional i2s through SAI and HAL in stm32 microcontrollers. I am able to configure single-direction i2s just fine. How ...
Hello, I am an engineering student who has just begun working on a CubeSat project for my design class. We are working on the OBC, specifically looking at developing a bootloader at this time. The OBC components have been selected by previous teams a...
Hello,after programming the code via the OnBoard ST-Link and connecting/disconencting USB on the Device side in order to find out if the works, I can no longer access the microcontroller.I have no idea what the rootcause is, 3.3V is fine. Could it be...
So the Blue Pill guy checks almost all the boxes for a new project I'm working on soon. 3 UARTS, M3, 72MHz, USB device, cheap, powerful *but* I'm not clear on the "fix" for being able to re-enumerate my device on USB. I must be able to change device ...
I want to use the bootloader feature (via UART) of the STM32L071RB. I have read the AN2606 and AN3155.If I'm right, the STM32L071RB has a V11.x bootloader and can be updated via UARTx, SPIx,and I2Cx.Is is possible to configure, which pins are used by...
Hi,My software sends a CDC bootload flag that asks the MCU to do a bootloader jump. The jumps works fine and I have no problem detecting the device change, in "control printers" on my PC (CDC to DFU). But on my collegue's PC his Windows does not see ...
