Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Hi all,First some context:I am attempting to use the USB designated pins (PA11 and PA12) as generic GPIO inputs at start-up as a way of determining if a host is connected to the device and make a decision whether to run the main code or not - I will ...
Hi to all,I need to update from FatFS from R0.11 to R0.12cIn R0.12c there are new implementations compared to 0.11.I see that for the STM32F401 the FATFS is in version 0.12c.Is there a way to update the library for the STM32F103 as well?Thank you.
Hello. I am using USB interface on STM32F746ZGT device (HAL lib, usb device mode). USB zero length packets are supproted and used by our protocol implementation on endpoint 1. It works on STM32L433, STM32F407, STM32F446 controllers. But it doesn't wo...
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...
