Hi We are using stm32f446ze mcu with 24 Mhz crystal and freertos in project.currenty USB cdc communication is getting about 500 kbps and want achieve more than this.ST documents says that max speed is about 1Mbps. Is there any reference or source or ...
Hello friends. the question is above.My plan is to take our in-house circuit, and connect an sd card "breakout" (i'm not sure how to call it.. is it caled a "socket"? an "adapter"? please correct me if i missuse the terminology), via an SPI periphe...
Hey guys,I am using a STM32F401RE nucleo board that does not have an ethernet port. However, I would like to send UDP Frames over the USB/serial port. Since I am new to this and there are no examples how to do it, I really appreciate your help. Has a...

hi,i programmed to interface USB from micro controller to PC, in PC using terminal software i try monitor the transmitted data, i tried with many terminal software(putty, hyperterminal, docklight, realterm) but i could not receive the data,but can re...
Hi all,I am working with the Nucleo-F446ZE board.I generated a project with CubeMx .At this point the project is running fine with UART interrupts and data.I debug the project and all is working.I need to use a delay function in my project. SO I have...
Hi,I am having some problem transmitting data over USB.i'm transmitting '|' and '.' continuously but i'm missing some data when i receive data .i'm getting like "||.|.|.|..||||.|.|"I generated code using CubeMX. Even in reference manual there is no c...
