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, am using stm32u585iot dev board i need all power code stop and shutdown and standby code for that board?
Hello everyone, I've designed a custom board with STM32H723ZG, previously based on STM32F767ZG. When I connect board with ST Link V2 prog through SWDIO, SWDCLK and GND, I get response that no target has been detected. I'm currently using ST-Link Util...
I'm programming a STM32H503CBUx Timer3. NVIC settings are such that the count down event is trapped in void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef* htim)This is a global interrupt routine that takes care for other timer interrupts as well a...
I am using the USB CDC driver code provided by ST in stm32cubeide, and am trying to figure out a proper minimum heap size. I have found various slightly conflicting answers, but the consensus seems to be that 512 bytes is not enough.In the same appli...
Hi, I am running firmware for USBX MSC device. The example project "Ux_Device_MSC" on demo board STM32U575I-EV. MSC device is enumerated on computer and FATS file system is used. It can transfer file from computer to storage on STM32U575I-EV. I am...
Greetings, I am trying to do a POC of LVGL migration to the STM32N6DK, https://github.com/STMicroelectronics/STM32CubeN6/tree/main/Projects/STM32N6570-DK/Examples/BSP For the POC i tried porting the LVGL into FSBL example above, but I ran into memory...
Hello,I'm currently preparing the firmware for a USB NFC reader (CCID). I'm working with the STM32F103 MCU and the ST25R3916 NFC reader.The STM32F103 MCU is programmed on a CCID USB device using the CCID USBD driver provided by STM32. The MCU acts as...
Hi,I am using STM32Cube_FW_H5_V1.5.0. I initialize a MPU region with the following code, using only LL-calls:LL_MPU_ConfigRegion(LL_MPU_REGION_NUMBER6, LL_MPU_REGION_PRIV_RW|LL_MPU_INSTRUCTION_ACCESS_DISABLE|LL_MPU_ACCESS_NOT_SHAREABLE, LL_MPU_ATTRIB...
I'm working with an STM32G431KBUx and trying to output a waveform via DAC1 using DMA and TIM6 as trigger (TRGO). I’ve successfully configured the DAC and DMA using STM32CubeMX. However, the DMA callbacks HAL_DAC_ConvCpltCallbackCh1 and HAL_DAC_Con...
I am currently using the STM32N657 to drive an 800x480 pixel display with 24-bit color. The problem that I am running into is the buffer that I need uses 1.1MB (800*480*3 = 1.152MB). Using just FSBL, I am limited to 511KB of SRAM. I know that this ch...
