How can I combine SD card and USB initialization in an STM32 project?Individually, both SD card and USB initialization work correctly. However, when combined, only the mount operation succeeds, and the process fails when opening a file. Testing each ...
Hi all,I know similar issues have been discussed before but I have not been able to find another post with the same issue. I am trying to use a CRC32 calculation to validate my flash memory, I am using KEIL IDE and the STM32L071CBT.This has been my c...
Hello,I want to use external SDRAM as the LTDC framebuffer with the STM32F746 microcontroller. I can write and read the desired data to/from the SDRAM without any issues. However, when I activate the LTDC, during the SDRAM initialization and config...
Hey there!Can we allocate the USB classes dynamically?Like, first we Initialize the USB Device stack, just register the CDC class and add its interface and start the USB Device Core (which pulls up the D+ line)This we need to do (atleast registering...
I have a working project that simply writes to a a file on an SD card (Using STM32H7B3I-DK, Not Using RTOS).When I add it to a touchgfx project, f_mount() and f_open() return NO_FILE_SYSTEM. This happens even after f_mkfs() returns FR_OK. I have the ...
I'm having an issue when using the DMA with SPI. I'm using the SPI for a 320x240 LCD and want the DMA to help with blocking while transferring large amounts of data with touchGFX.I'm able to paint the screen one color just using the SPI but when I t...
Hi:I now have a STM32cubeIDE project now successfully sending FDCAN messages to PCAN View running on my laptop. I'm now trying to add the emotas CANopen FD single line software stack to send CANopen messages. I can not get my program to build without...
The documentation for HAL_ADCEx_MultiModeStart_DMA clearly states that the length parameter is in bytes. /** * @brief Enable ADC, start MultiMode conversion and transfer regular results through DMA. * @note Multimode must have been previously ...
Hi I have a STM32L433 running at 16MHz and having a strange issue. I have setup the rtc and within the Systimer interupt I display the current time (the systimer is 1KHz and every 1000 ticks I get the second , at this point I read the clock and di...
Hi to all.I'm starting a new project where we use the STM32H7S3V8H, and with the code generated with the STM32CubeMX (see IOC file attached) it compiles perfectly the Boot code but the Application code allways fail with the following error message:"c...
