We have a custom board with an STM32F407 on it. I used CubeMX to create the project and enabled HTTPD. I used the example LwIP_HTTP_Server_Netconn to get a webserver running. I have a few pages working including a dynamic page. Next step was to c...
Hi,I am trying to send and receive the float variable between STM32H745 and my PC. I can only transmit and receive strings. Is it even possible to handle any type of data rather than string. Thank you.

Hi, trying to order the free NUCLEO-H723ZG board with the code that was provided.After applying the code for the first time the order page asks to login with my username.I did that to complete the order, but then it's impossible to apply the code, as...
Posted on May 31, 2017 at 23:17 I am trying to make usb operate in STM32F103 but it seems doing so is a lot different than usb fs in STM32F4 series. In F4 series it was just enough to connect usb connector to Data pins and MCU would take care of ...
Hi everyone.I ordered the B-L462E-CELL1 Discovery board from Mouser last week and finally got around to setting it up. The board came sealed in its clamshell packaging inside a stapled plastic bag. However, I am not allowed to activate the device via...
Hello everyone,I want to connect my STM32H747-Disco board to my AWS IoT services and the AWS S3.I've attempted to do it with minimal changes with the aws_Demo application project from the X-CUBE-AWS V2.2.0 expansion package:First try: I've just follo...
Hello everyone,I am trying to use USB on the STM32 NUCLEO-L4RZI-P dev board to work as a Communication device class (CDC).I have initialized the USB using the Cube IDE.After initializing, I tried sending data using the " CDC_Transmit_FS( buffer, size...
My mcu is H743, the MDMA is enable for SD. The FATFS is used to operate file system. CubeMX is used to generate template code.Without the FreeRTOS, both of the FATFS functions f_write() and f_read () work correctly. But when the FreeRTOS is used, f_w...
As part of my thesis, trying to get as much data transfer from PC to STM32 as possible. As I am going to transfer a video stream, isonchronous transmission seems to be a good choice, but I don't know how to do it properly.I use STM32H743 microcontrol...
