Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
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/BSPFor the POC i tried porting the LVGL into FSBL example above, but I ran into memory o...
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...
Recently, I encountered a tricky problem, I used STM32F405VGT6 this IC, but I found that it could not enter DFU mode normally, after repeated troubleshooting, I found that when the chip was USB probed, HSE was detected and did not vibrate, I also saw...
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...
Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
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...
We have a STM32070CBT6 with minimal connections (schematic below) and it appears to be unresponsive to USB enumeration, although it does pull DP low to trigger it. This occurs when hotplugging it or holding reset low for a few seconds. I've checked t...
Hi, I am testing the System Memory UART protocol in STM32G070CB.I tried the Get command, the Go command, and the Read Memory command standalone, all success.However, when I try to execute the Read Memory command, which is successful, and then execute...
