Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
I cannot get OTG_HS to communicate with a USB host, and I'm out of ideas. Any help would be greatly appreciated.The problem:I've instrumented HAL_PCD_IRQHandler to print whenever an interrupt occurs. Right after USBD_Start, I get:0x800 (USBSUSP)0x100...
Hello STM32 community,I am currently working on an embedded application using the LPTIM1 (Low Power Timer Mode) on an STM32WL55JC16 microcontroller. My goal is to count pulses from an external signal connected to the BP5 pin (assuming this is the cor...
Hi - I am new to the STM32CubeIDE - moving from Attolic.I have created a new STM32 project using STM32CubeIDE 1.9.0 for a STM32L151VET6 using New Project.Our board is built to use an internal oscillator. I can try to debug the basically empty new cre...
Hi everyone, I am using the STM32U5G9J-DK2 board and have generated the USB Video Class (UVC) code using CubeMX. However, I am new to both this board and UVC, and I am facing difficulties in understanding how to proceed further. I couldn't find any s...
I use STM32L431 to enter STOP1 mode, the original power consumption is 53uA. Before entering stop mode, I call HAL_ADC_DeInit(&hadc1) to disable ADC, and call MX_ADC1_Init() to re-enable ADC after exiting STOP1 mode. The measured power consumption is...
Moved from https://community.st.com/t5/stm32-mcus/stm32-arduino-stm32duino-tutorial/ta-p/49649 After you have finished the arduino project, how do you then remove everything from the MCU and use it again for normal STM32 projects in CubeMX and so on?
Good morning everyone!I have a question regarding a USB to UART IC. I’ve seen that the FT231XQ is used in ESP32s to program and communicate via UART. Is it possible to do the same with STM32s?
Microcontroller : STM32L476RG, External flash : AT45DB041E (4Mbit, 256 bytes of page, 2048 bytes of block),SPI2 communication protocol, using HAL.I am not able to use the LittleFS library in order to read a file that is written into the flash or any...
I am new to Arm but old to assembly coding (inc Toshiba 32 bit CISC - now extinct).. Just completed RCC startup code for a STM32F344 chip by looking at the 1124 pages (!) of the RM0364 manual and the CUBE LL start up code (!!!). The CUBE code has wai...
Hello, we have Custom PCB Board which Build's around Stm32F4 Series Micro Controller.In which we have Two USB Port, One Connected with External ULPI (High Speed 480mb/s) Another Connected with internal ULPI (full Speed 12mb/s). And we are U...
