Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello!I have an MQTT project using NetX Duo, which publishes MQTT messages to a remote server. But, before it can do that, a secure connection must be established using TLS v1.2, which takes about 18-20 seconds (checked while debugging and stepping t...
I’m trying to build a UAC2.0 (USB Audio Class 2.0) device on STM32H7, supporting: High-Speed USB24-bit audioPlayback + RecordingFull-duplex, stable, low-latency operation After reviewing many threads here, I still haven’t found a complete or working ...
Due to more performance requirement, i wanted to change the ThreadX timebase to 1ms. To what i have researched till now i need to make the following #define TX_TIMER_TICKS_PER_SECOND to 1000 which is usually set at 100 which is 10ms. Any idea what el...

Hey. I'm trying to use my H7's usb interface and i've currently set it up as a cdc device.What i'm trying to implement though is the following. The stm is supposed to create a virtual connection with either a python app or a tera term terminal.Is the...
I am working on an STM32 + Azure RTOS project where I need to access the same SD card in two different modes:When the microcontroller accesses the SD card directly, I use FileX with an SDIO/SPI driver.When the SD card is connected to a PC via USB, I ...
I am trying to initialise SDRAM on STM32H757I-EVAL.I created a new demo project in STM32CubeIDE using the specified evaluation board. I disabled the other memory peripherals like MMC, etc. It calls MX_FMC_Init() but after that, when looking at memory...
Hi,I'm using STM32H7 dual core, where the data has to be shared between the cores, so im having totally 21 variables totally 76 bytes, thought of do it like a structure, so where to place the structure exactly for this data sharing. so, this structur...
Hello everyone,I wanted to ask you about a problem we are having with the combination of the STM32H7 chip and a 16-bit SDRAM memory, AS4C16M16SA.To give you some context, we are reading data from a sensor, a radar, which generates 18432 bytes per fra...
Hi, I use STM32H7 with STCUBE 11.1.I use RNDIS module usbd_cdc_rndis.h to communicate with a PC.Sometimes when the PC sends a frame the STM32 replies with NAK, here is the sequence that repeats:SYNCPID OUTAddressCRCEOPSYNCPID DATA0data 30 bytesCRCEO...
