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...
I am following the Azure tutorial using the B-L475E-IOT01A Discovery kit to connect to IOT Hub via MQTT.Tutorial: https://learn.microsoft.com/en-us/previous-versions/azure/iot/tutorial-devkit-stm-b-l475e-iot-hubI pulled the example source from git an...
The STM32Cube API provides several helper macros for working with ADC data, including:__HAL_ADC_DIGITAL_SCALE(__ADC_RESOLUTION__)__HAL_ADC_CONVERT_DATA_RESOLUTION(__DATA__, __ADC_RESOLUTION_CURRENT__, __ADC_RESOLUTION_TARGET__)__HAL_ADC_CALC_DATA_TO_...
Hello, I am following this guide:How to integrate TouchGFX and camera middleware on an STM32N6570-DK and seem to be getting an I2C1 undefined reference (below). Is there something I need to change? I have I2C2 enabled in my .ioc, but don't see anyt...
I'm using an STM32H7S78-DK board and I have a part of the firmware that, from the boot, updates the FLASH from a .bin inside an SD cardThe code is pretty simple as I loop the FLASH comparing every sector with the one in the SD card and, if different ...
Hi,I have developed an application for the STM32C562RET microcontroller that wakes up the MCU from standby mode, initially based on an example provided by ST. The non-FreeRTOS version of this application works fine; it wakes up the MCU from standby u...
Hi,I’m developing a custom external loader (.stldr) for an STM32N655X0 custom board to program external XSPI NOR flash using STM32CubeProgrammer via a J-Link interface (board does not have ST-LINK).I have the loader framework working partially:Init()...
Hello all, I've been having trouble with the ADC system on the STM32G071G8U6. I'm using the STM32CubeMX to generate initialization code. I have 5 external A/D inputs and it appears I am not getting readings anywhere near the real values, so I have ...
Hello ST Community, I am facing a USB bulk OUT transfer issue on the NUCLEO-H755ZI-Q board. Hardware / USB Setup I am using an external USB3300 ULPI PHY with the STM32H755 USB OTG HS peripheral. The device enumerates successfully in High-Speed and Fu...
Hello, I hope you are doing well. I am currently working on benchmarking the Ethernet communication interface on an STM32H753 Nucleo board. My setup involves sending data from a Python script to the STM32, where the data is encrypted, and then sent b...
I'm trying to get the SAI working on the NUCLEO-N657X0-Q but I'm not having any luck. I tried the interrupt API and I got it somewhat working but the supposedly non-blocking API seems to block on the first call to HAL_SAI_Transmit_IT. The DMA configu...
