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 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...
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...
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...
Hello Community,I have been attempting to use the STM32CubeIDE to combine two examples:https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/NUCLEO-U545RE-Q/Applications/ThreadX/Tx_MPUhttps://github.com/STMicroelectronics/STM32CubeU5/t...
I'm implementing UART communication between an Arduino Uno and an STM32L476RG. When the STM32 acts as the master (transmitter) and the Arduino Uno as the slave (receiver), data transmission works as expected. However, when I reverse the roles—making...
