microROS: Messages being published at only one hertz

I have implemented microros on an stm32 nucleo f446re and wrote a publisher in it, while using default qos the messages published can't exceed the frequency more than one hertz even after removing the delay function.....Is there any way to increase ...

Resolved! USB device audio class up or IN stream not working.

Device: STM32F411RE NUCLEOHello, I am having some issues with STM USBD AUDIO library. For some reason I cannot get it to stream audio data to a host device in a proper way.The device is successfully recognized as 2 channel 16 bit microphone by my PC....

STM32F4 Discovery USB Audio

Hey,I am trying to send some sine wave signal over usb audio class to computer. I arranged usb descriptors so computer recognizes mcu as microphone but I am struggling to send sine wave. I create sine wave with dac and I read it with adc. what should...

Have two USB Audio Device Class

I have a STM32F446 MCU. I want to use the two USB ports featured by the MCU and have a single Audio Device Class on each USB but once one is selected in the CubeMX, the other is greyed out.

Using MP45DT02 on STM32F407 Discover board to save data using DMA.

I am wanting to sample the MP45DT02 microphone data. I am very much a beginner with this but I have cobbled together some code from some examples. Any input as to why I am not able to see any data through the DMA would be greatly appreciated. DMA_In...

why program counter goes to HardFault_Handler whenever it receive data on TCP server

Dear All,I'm using STM32F429ZI-Nucleo for Ethernet, I'm using this board as TCP server, Connecting with client Thats working fine but whenever client send data to server MCU going to HardFauld_Handler, I'm not able to identify this issueKindly guide ...

Receiving SPDIF data with STM32F446RET/CubeMX does not work

I'm trying to receive SPDIF data using an STM32F446RET using PB7 as SPDIFRX. The signal itself is perfect, a clear and sharp waveform can be seen directly at the input pin. The whole stuff is configured in CubeMX which also generated the code for int...

Hi everyone, I'm looking to design and develop a USB Audio Interface using STM32F4xx series MCUs that could ideally record up to 16 channels of analog audio signals, convert and send to a PC / MAC via USB.

If anyone is familiar with Digital Audio Workstations (DAW's), you can then select the type of audio input device in the application, to then choose which channel to monitor and record.I'm familiar with the process of how to record the incoming audio...

STM32F446 Nucleo board USB FS some sort of frame issue

I'm stuck. I'm able to send a 440 Hz sawtooth wave to output over USB from Nucleo board (device) to my computer (host).The only problem is, there's this repetitive clicking / choppy sound in the resulting audio when I record with Audacity. The click...
