Hi,First I'm new to the STM environment.I'm setting up the Board to test some stuff, with raw LwIP. I'm having a weird issue, where the board freezes when i plug in a connected ethernet cable. I made no other changes (exept one, look below point 3)Co...

I am using STM32H7A3 board. I am trying to integrate SD Card using SPI. I am getting FR_DISK_ERR when I try to do f_mount. Attached source code.

When i tried to give Pull ups for SPI pins except SPI1_SCK, i am getting FR_NOT_READY error.I am completely stuck in this issue. Please have a look into this and provide a solution for me.Thanks in advance.Jestina

Hi, I am using a STM32L496. On the board is a buzzer. If the buzzer works, an USB connection lost the transmit functionality. Receive is still ok. The supply voltage is stable regards Josef

Integration of a position dependent library (binary) in a threadx module ( position independent )

Hi, I am working on threadx. So to set the context, Module manager will host modules.All the modules are compiled as position independent. Module manager however is not position independent.Scenario : a third party library (binary) has to be used in ...

How to stream out data via USB HS with CDC Interface

Hi,I want to achieve following:I want to read out an ADC (16-bit at 1MSPS) via SPI and stream those data to a Host PC with the Nucleo-F722ze and the USB_CDC_Interface.The amount of data per second is to high (16Mbit/s) for USB_FS so I am using USB-HS...
