USB PD Audio Accessory connection
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...
Resolved! Drive is not shown in my computer in example of STM32F769I_EVAL board testing
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...
Resolved! How can you tell if HAL_UART_Transmit_DMA() function has not finished?
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...
Optimization Settings for HAL Driver (STM32F7)
Hello,I have a project with FreeRTOS and LWIP (plus some other stuff). I ran into the problem, that if I set the optimization for my project (-O3 in my case) I get weird communication glitches. For example I only get a reply every 3rd or 4th ping, Pi...
H743ZI lwIP TCP assign more memory

[CUBE OTG] Incorrectly set HFIR.FRIVL
In CubeF4 v1.21, OTG_HFIR is set in USB_InitFSLSPClkSel() to either USBx_HOST->HFIR = 48000U;or USBx_HOST->HFIR = 6000U;which according to the RMs is incorrect, as they should be set to value one less.This has been already noted by @tsuneo her...
LWIP recompilation
Hello Dear DevelopersI don't know what is the procedure, but when a file is added to the project, the compiler no matter if it is Keil, STM32cubeide, or IAR, does a complete rebuild while LWIP is added to the project. What should I do or What I can d...
