Hello everyone.
I'm new in AudioWeaver, however I already have some layouts worked with my stm32f4 board. Now i'm trying to make some works on stm32h747. I put bin file on board and i get board connect to audioweaver. However when i stream sound from pc or try to speak on microphone nothing coming from this channels. I put a meter at the beginning and you can see that nothing out. I add a sin signal with 600 hz and get sound on output. Can you please give some clues about this?
Thanks,

Hello Ibrahima,
Understood about your situation. Where did you get the .bin file to flash the H747 board with? I only ask because if you obtained it from our Downloads page, it is probably not the correct BSP/.bin file for the H747. The H747 is fully supported by DSP Concepts, however the flashable .bin files we publicly provide are only for the STM32F407 (M4), STM32F769i (M7), STM32F746 (M7) ST Micro boards. This could be part of the issue you are experiencing. Please let me know and we can go from there.
Thanks,
Kevin

Hello Kevin,
Thanks for your prompt response. Yeah we have a deal with DSPC and then i get my bin file from BSP provide directory : stm32h747i-discovery-single-core/SampleApp/STM32H747i-SingleCore/Bin/SW4STM32

Hello Ibrahima,
Ok thanks for the information. Could you please let me know which mic arrays you are using. Also, could you please send a screenshot of your Audio Weaver Server preferences: Audio Weaver Server > File > Preferences.
Thanks,

Hi Kevin,
For now i did not plug a mic arrays yet. I just try to to get audio from PC via USB, or via Line-in or via embeded microphone mp45dt02. As I know stm32h747 have a Sys_In with 8 channels: 2 for USB stereo , 2 for Line-in and last 4 for microphones. Which one of last 4 is for embeded microphone?
You can find my server connection attached. Thanks!

Hello Ibrahima,
I checked the BSP that was delivered to you and verified that your input source channel assignment is correct. The last 4 input channels are programmed for our 4 mic daughter-boards that connect via the “Audio Con” - CN17 connector on the H747 board. The default BSP we provide does not support the embedded microphone, meaning if you'd like to use it as an input, you'll have to edit the BSP.
Thanks,
Kevin

Hello Kevin,
Your help was very helpful, and of course i get my microhpones from a board plug on CN17.
Thanks a lot! I will open another thread soon to talk about the module Sensory
