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...
Hi ST, i have one question for you. Could you please make "examples" more messy? Is it even possible? Lets see, i believe you can do it even worse. To be honest, i have never saw this nonsense and mess in my life. And i have also worked as ABAP devel...
Split from this thread. I did and it is all the same. Here is an example when I measure on port PB1 the voltage from VREF divided by 3 (2.5V/3 = 0,833..V). Voltage checked with multimeter. /* USER CODE BEGIN Header */ /** **************************...
Good morning everyone,I’ve encountered some unexpected behavior while debugging my application. I’m trying to connect to an MQTT server and publish a message using the embedded Ethernet port, LwIP, and FreeRTOS. I’m developing with CLion IDE and CMak...
Hello,I am trying to implement a USB HID keyboard on an STM32F042 without HAL or LL, just simple register defs. I took an example code generated in CubeIDE with HAL and a few other examples. I extended the example with HAL to also implement the LEDs ...
I'm already achieved a USBX-MSC class, and also a FileX in MCU local.I know that using two file systems at the same time is not recommended, but still have some questions. 1. I implement the ux_deveice_msc.c as followed. Use PC-Windows to create a f...
In a project using the STM32L451RET6, SPI3 is configured as follows* Full Duplex Slave* Hardware NSS Disable* Frame Format Motoroloa* Data Size 8* CPOL High* CPHA 2 Edge* DMA: * SPI3_TX Ch2 Mem to Per, Priority Low * SPI3_RX Ch1 Per to Mem, Priorit...
I am trying to use pins on ADC3 of an STM32h735g in Zephyr, but I am getting a "Could not read (-22)" error, despite not having issues with ADC1. Is ADC3 supported? If so, can you help me with how to configure it?This is based on the Zephyr samples/d...
HelloI am using STM32H7R3L8 MCU and STM32CubeIde v1.19.0. I have an issue where if I was to use SPI4 in Motorola mode together with CPOL=0 and CPHA=1, it works fine. It also works fine when I was to do SPI TX via DMA. Although, as I have the need to ...
Hi, I'm using an STM32F746bgt6 on a custom board, and I'm using Keil.I enabled LibJpeg in CubeMX, but I can't get an RGB JPEG.I have a .jpeg file saved in flash, "frame99.jpg," which I read via littlefs. When I read it, I allocate the buffer to exter...
I'm using the nucleo-H753ZI board to test mcuboot.The setup works and I can successfully run the bootloader and the application in slot0_partition using zephyr sysbuild.However when trying to upload an image I get the following flash write error:[00:...
