I'm getting USBD_BUSY when i try to transmit data via virtual com port
char *data = "Hello World"; while (1) { HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin); HAL_Delay(1000); CDC_Transmit_FS((uint8_t*)data,strlen(data)); }uint8_t CDC_Transmit_FS(uint8_t* Buf, uint16_t Len) { uint8_t result = USBD...

Please give a reference link on Stm32f429 how to interface with HP printer Usb printer class
Resolved! Which Ethernet PHY to choose for STM32 ethernet applications?
I'm developing my first STM ethernet application and want to use it's built in MAC, from my understanding any 10/100 ETH PHY with MII or RMII should work but there's such a big list of those on market, ST Disco boards I found use LAN8740, which is ex...
[USB HOST HID] Is there any sample code for reading data from two interfaces of the same device?
Hi, I was able to operate the wired keyboard, and wired mouse, according to example videos.I am trying to adapt the library code to read data sent by the device, but HOST is restarting the connection every time the device sends from a different inter...
Create Azure RTOS Project for STM32L4S5 Discovery Kit
Using the STM32L4S5 Discovery Kit board (B-L4S5I-IOT01A), I have gone through the sample CMAKE getting started projects from Microsoft as well as tested the STM32Cube IDE sample projects. Both packages appear to be developed by ST. The CMKAKE version...
RMII problem STM32F7, receive OK, transmit not working
I am implementing ethernet on bare metal STM32F746-DISCO board. I configured rmii, set the PHY interface and "happily" receiving packaged on the DMA buffer. Problem is that sending doesnt work. Before setting TX descriptor for first package, DMA_SR f...
How to programming EWB-Sterling(contains STM32F4X MCU) with FT4232HL in JTAG mode ?
I designed a custom board with FT4232 and EWB-STERLING MODULE.the module contains stm32f4x MCU, I struggled how to programming the MCU with OpenOCD and JTAG with (FT4232HI try to help with LAIRD but no one knows how to help me and refers me to ST.ple...
What are the timing constraints on BOOT0 and \RESET ?
I need to know the timing constraints for bootloading (over UART). How long must \RESET be held low to reset? How long must BOOT0 remain high after \RESET is released? I need this for the STM32L4P5, the STM32F423, and the STM32G031. I apologize ...
How to properly configure DMA in order to use linked list in non secure Application (TZEN = 1) on STM32U585
Hi,our porject use TZEN =1;A custom Bootlaoder (secure app) is executed at begin and after we call a non secure Application.The non secure Application as already been tested/validated with TZEN = 0.This application use GPDAM channel 10 ro read data f...
