I generated my code by stm32cubemx, and use ucpd1 as sink&dead battery, use ucpd2 as drp. But got USBPD_ERROR in USBPD_DPM_InitCore after execute " CHECK_PE_FUNCTION_CALL(USBPD_PE_Init(USBPD_PORT_0, (USBPD_SettingsTypeDef *)&DPM_Settings[USBPD_PORT_0...
how to know it is a usb charger or PC connect to the stm32 USB device mass storage?
I am transferring 307200 bytes (640x480 gray) from DCMI to AXI SRAM using DMA1. When I do single transfer mode to do snapshot captures the DMA driver state never changes back from BUSY to READY so I can't start another. I did 'fix' it with a hack in ...
This is a documentation bug/request really, but I recently was trying out the HAL_SPI functions for the first time, and had set up the peripheral for 16 bit transfers.The documentation for HAL_SPI_TransmitReceive and related functions, for several of...
Hi experts, I am designing a circuit using STM32 MCU, my application doesn't require strong MCU , so i decided to use 2 type of below MCU: STM32F103C8T6STM32F030F4P6But i want to load the hex file to chip via on board designed circuit by micro USB po...
Hello guys!In our project we use STM32H750VBT6 MCU and an external NOR-flash chip W25Q128. Tell me please can we use XiP technology and FATFS file system on this flash memory simultaneously? Might there be a conflict at the QSPI level or at the memor...
Hello,Various CubeMX generated files related to USB, such as "usbh_conf.c" and even "stm32h7xx_ll_usb.c", are littered with HAL_Delay() waiting up to hundreds of milliseconds and therefore halting threaded application execution. Every time I switch U...
I'm working on STM32F746 Discovery try to use STemWin. I using cubeMX to gen code for cubeIDE. But i'm stuck, sprintf %f not working. It's return 0x00 and dot instead. For example char str[32];float a = 123.456;sprintf(str, "%f", a);the resultstr[0] ...
