Hello, I am working on a project with an STM32f446 and I need to disable all interrupts while executing a specific critical function. I put in my code the following lines : __disable_irq(); Critical_function(); __enable_irq();But I still...
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...
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...
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...
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 ...
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...
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 ...
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:...
hii am working on stm32f746 disco board and i want to play audio with board from online udp data. for this target i wrote a qt application to send pcm audio data over udp protocol and in stm32 program i use lwip receive function in a freertos task fo...
