Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
In debug mode, __HAL_DBGMCU_FREEZEZE_IWD() was used to stop the IWDG. Later, the HAL_Delay() function results in an infinite waiting state. I'd appreciate it if you could let me know the cause and solution.
I am working on an application based on STM32F103 chips.After build the application, I do full chip erase using ST-LINK Utility and then flash the chip using new .hex file.I know that STM32 starts executing the code at the address of 0x8000000. Howev...
Hello.I'm using STM32L476RGT and I have a question regarding uart error recovery.MCU is talk to slave MCU via UART, actually rs485.Now main MUC is talking to 3 slave MCUs via UART and it's working well but randomly, there happening uart error.Error c...
Hi All,Does anyone know is there any board that come with another USB port (not for the ST-Link Debugger) that I can use it to test out my CDC (VCP) application? Please help to share here. Thank you.RegardsYong
How can I upgrade the firmware of STM32F446RE Nucleo board using USART bootloader from Linux? I have successfully upgraded firmware using USB-DFU using dfu-util library that is present for Linux but I want to do the same through USART. How can I do t...
I was using USB-DFU for uploading LED related codes on STM32F446RE but then I came across bootloader selection flowchart which I am attaching with this question. According to this flowchart, I won't be able to access the bootloader mode in presence o...
If you select Ethernet, LWIP, and USB Device in CubeMX and press ok to return back Keil IDE. After import is done, Ethernet, LWIP, and USB Device files are NOT added into the project. "Source Group 1 is empty". You can not compile the project. are th...
What the __STM32F?xx_HAL_VERSION constant, defined in stm32f?xx_hal.c (where ? is STM32 cpu series) is for ?I would like to use this constant to check at compile time and display at run time what is the HAL library used in the firmware...But with my ...
Hi, I'm testing a code using Nucleo-L476RG and an analog to digital converter. This ADC uses SPI communication and shares its RDY (end of conversion) and DOUT functions on the same pin, that is, after reading the converted data on the pin, it become ...
