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...
This question is about the operation of HAL_SPI_TransmitReceive_DMA.When HAL_SPI_TransmitReceive_DMA(&hspi1 ...) is being transmitted (assumed SPI communication_A) and HAL_SPI_TransmitReceive_DMA(&hspi1 ...) is called (assumed SPI communication_B) SP...
Hi all, I have just released subj. I have tried to contribute it to SQLite directly or to create a CubeMX package but seems that nobody interested, so I have created a standalone repository. I have used STM32H753I-EVAL2 to develop and test it and the...
