The private variable "FLASH_ProcessTypeDef pFlash" in stm32h7xx_hal_flash.c is used in some functions I notice that it is not initialize by any function.So for example the first time a call is made to: FLASH_Program(uint32_t TypeProgram, uint32_t Fla...
Hi ST GeniusesSo, for quite a while I have been trying to create an USB audio mic. Problem is: it is quite hard and not always a complete solution.And the X-CUBE-USB-AUDIO offers the complete solution, for audio and playback, even with feedback.The p...
Hello everyone,I am working on an application about updating stm32f103 via built-in bootloader - uart.I have a bin file that is validated with cheksum equal to st-link utility tool. (sum all the bytes).My issue is that sometimes with the same bin fil...
I hope someone can help me, I'm trying to mount my SD-Card and following that writing data on it. While trying to mount the SD-Card to the Microcontroller the mounting process gets stuck in the while-loop mentioned in the picture attached to the post...
I am studying USB PD. I am using the demo board B-G474E-DPOW1 and the project from the STM32CubeG4 examples. When I connect the USB-C cable to the charger, after the ATTACH event, I receive a list of possible profiles from Source. But when the cable ...
Hi all,I'm working on a project that will communicate via SPI. I want to use DMA for it. I have some problem getting HAL_SPI_TxCpltCallback to be called. I've followed the debbuger and I think I've found what's wrong. It seems that the SPI_DMATransm...
Hi,I have STM32F413 Discovery borad and want to implement fatfs in external flash(N25Q128A13EF840F) of EVB.Do you have any doc or examples code that you can refer to?
I am working with demo board B-G474E-DPOW1 and the project from the STM32CubeG4 Sink examples. I am trying to figure out how to connect an Audio Accessory. I have such an adapter. When I connect it to the usb-c, I expect to see an event with the conn...
Hello ,i am testin my STM32F769I_EVAL board for USB Host Mass storage example from below project example C:\Users\Graffin01\STM32Cube\Repository\STM32Cube_FW_F7_V1.15.0\Projects\STM32F769I_EVAL\Applications\USB_Host\MSC_Standalone\SW4STM32but i could...
I have been looking for something in the structure. while ((huart1.hdmatx->State != HAL_DMA_STATE_READY) && (huart1.hdmatx->Lock != HAL_UNLOCKED))But that does not seem to work. The only other way I can think of is when you call HAL_UART_Transmit_DM...
