Hi,I am new to HAL libraries and currently working on a small CAN bus consisting of two STM32F4-discovery boards connected to a CAN transceiver connected to the bus. Both transceivers are externally powered with 5V.So far, I tried the existing CAN ex...
I got my SPI5 running the way I want it but now I want to move to DMA. When I do this the SPI lines remain low after sending its data. So I assume my config is off. Using the IOC to make changes I only see the fowling added. /* SPI5 DMA Init */ ...
How configure port ,how get _port_status work,
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
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...
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...
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...
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...
