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, I am having a strange ADC problem on my STM32L431 device. I am sampling 6 channels without DMA using polling method with the following code: while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ ADC_Select_CH0(); HAL...
Hello,I have been trying to read/write into an SD card using the SPI or SDMMC method with Fatfs. I wasn't able to make use of the filex option for file operation which is provided in the STM32u5A9 libraries, since I am using FreeRTOS in my project (a...
Hello, I am using an STM32G0B0 and am debugging the process of the bootloader handing over control to the application.The bootloader goes through its handover process without an issue.The final part of the bootloader handover looks like this.{ p...
Hey everyone!I'm trying to detect the rotations of my rotary encoder. I used external interrupts to detect when the state of the pin changes. My problem is that it seems like when the encoder bounces the interrupt gets triggered, but the state doesn'...
Hi!I am having big troubles getting USB-PD sink on the STM32G431KBT to work. I am using CubeMX and following the AN5418 Complete USB-PD application example and using FREERTOS 10.3.1 and USBPD 3.3.0.Connected to my wall adapter the debug traces looks ...
I am using STM32H7B3I-DK running a touchgfx application and acting as SPI Master, and Nucleo-H743ZI as SPI Slave. Both are configured in interrupt mode not using HWNSS. The Master is sending 1,2,3,4,5,6,7,8 but the slave is receiving random numbersI ...
This is a question about programming style, preferences, efficiency, and risk.We are working on a state machine were multiple conditions are checked for a potential state transition. We are debating what is better, safer, more efficient, or simply mo...
We are currently using the ST32F4 MCU.During operation, we are using self-diagnostic code provided by ST, but after 8 days of normal operation, an EXT_SOURCE_FAIL occurs in STL_MainClockTest(), causing the MCU to reset.When EXT_SOURCE_FAIL does not o...
Hi All,I'm having a terrible (fun) time trying to get the DP83848 to work with the STM32H743 (RMII).No packets, no interrupts, nothing. - it's just dead to the world.I can get things working with the LAN7842 and I can get the DP83848 working with the...
Hello there. I am working on STM32G030 based FW. It appeared the TIM1x_CH1N doesn't work. I found out this part of code doesn't initialize negative channel(stm32g0xx_hal_tim.c). Moreover it may skip all channels configurations. It seems to be a hard...
