Need tutorials/resources on "USB MSC" and "eMMCs/external NAND flashes"
I was gonna make a project that can map USB MSC to an eMMC or external NAND Flash memory. but my knowledge of FSMC and SDIO is not enough and also I haven't worked with USB peripheral.my choice of MCU is STM32F407IGT6.can you help me find good resour...
USB Composite device: how to make two virtual serial ports independent?
We have an embedded device (STM32) that connects to the PC via one unique USB. The USB connection offers two virtual serial ports. Device description is:0xEF, /*bDeviceClass*/0x02, /*bDeviceSubClass*/0x01, /*bDeviceProtocol*/and interface...
USB audio overwrites received data
I want to build a simple USB audio interface using STM32L432 Nucleo board. The device is detected by the computer but the sound is not played correctly. Even if nothing is played, the whole buffer is filled with 0x00 except two bytes. This is repeate...
Resolved! UDP Echo server example is not working(Nucleo-144 for STM429ZI)
I used example from STM324xG_EVAL\Applications\LwIP\LwIP_UDP_Echo_Server\Src.I add lwIP into the project using CubeMX. ping test is good. I sent the message using Hercules tool. but Necleo didn't receive massages .there are CubeMX setting value.I ...
Resolved! STM32F7 MAC-to-MAC possible? With HAL?
The STM32F7 supports Ethernet with MAC (and DMA), according to doc en.DM00224583.pdf.I try to connect it to a KSZ9896 (ethernet switch) that provides a direct MAC interface in RMII.The KSZ provides configuration bits similar to the STM32 ETH_MACxxx.I...
How to configure audio output over USB using NULCEO-L476RG?
Hi,I want to create a simple device that streams audio from a PC to a loudspeaker via NUCLEO-L476RG board. The connection to a PC is implemented via USB connector on the X-NUCLEO-CCA02M2 board, which is plugged into NUCLEO-L476RG.I've configured the ...
USB flash drive detection not working
Hi,I am using STM32F205RET6 customized board and trying to mount the USB flash drive like below, but am getting FRESULT value as 11 (FR_INVALID_DRIVE, /* (11) The logical drive number is invalid */) FRESULT fr;FATFS fs0, fs1; fr = f_mount(&fs1, "1:...
Resolved! How to transmit non-echo TCP packets using Netx?
HiI must have done something wrong in the function below to transmit a buffer on a tcp socket. If transmitting up to 4096 bytes the function works fine. If len is greater than that, nx_tcp_socket_send fails. How to stream a buffer correctly using Net...
