STM32F769NI just bought and need some help

Hi Guys,

 

I just bought the STM32F769NI. I understand that AWE_BSP_stm32f769i is the software.

 

Do you have an installation protol/instructions for this board. Do I use the STM instructions then load the DSPConcepts programme??

 

All very confusing.

 

Hope someone can shed some light on this…

 

BTW: I want to implement 3-Way Speaker and Equalisation on my audio environment. Hopefully I can extract the I2S or digital an send the processed signal to the external DAC’s.

 

I am very keen, but my technical abilities are few.

Hi D, When you download and install the AWE_BSP_stm32f769i_s1.0_Installer.exe, you'll find a User's Guide with installation and usage instructions here:

Hi Matt

 

Thank you.

 

I hope the board comes before the weekend.

 

Will the instructions tell me what to do with – Audio_Weaver_Designer_7.A.08_STMicro.exe.

 

I am confused, there are a few software files???

 

Regards

D

Hi,

 

To clarify a few things:

The Audio_Weaver_Designer_7.A.0.8_STMicro.exe application that you mention is the installer for our Designer tool. This gets installed on your PC and is primarily a GUI that allows you to easily generate audio signal processing flows. You can run this tool on your PC (also called the Native target) to easily generate and test your audio flows, and you can also connect this tool to an embedded target (in your case the STM32F769i Discovery board). Once you've installed Designer on your PC you can browse through the Docs folder to learn more about using Designer.

 

The downloadable application that Matt listed above ( AWE_BSP_stm32f769i_s1.0_Installer.exe) is an installer for the STM32F769i BSP (Board Support Package). This BSP comes with a user guide that explains how to flash your target with the binary image (.bin file) included in the package and how to connect Designer to your target once you've flashed it. The supported audio topology (input and output audio sources) for the target is also explained in this user guide.

The BSP additionally contains the source code and build projects used to generate the binary image for the target, so users can modify and rebuild the binary as desired.

 

STM32F769i BSP does not support I2S output out of the box. To enable sending audio over I2S (or SPDIF), you will have to modify the source code to enable this interface and pipe your audio through it. STMicro documentation for the STM32F769i Discovery board can be used to guide this process.

 

I hope this helps answer some of your questions,

-Axel

Hi Guys

 

Thank you. I cannot contain my excitement. Thank you!!!

 

So, to confirm: BOTH Audio_Weaver_Designer _7.A.08_STMicro.exe & AWE-BSP_stm32769i_s1o_Installer.exe go onto the PC?

 

Ooops: STM32F769i BSP does not support I2S output out of the box. To enable sending audio over I2S (or SPDIF), you will have to modify the source code to enable this interface and pipe your audio through it. STMicro documentation for the STM32F769i Discovery board can be used to guide this process.

 

I bought the wrong board?????

 

But the board has both SPDIF RCA out and SPDIF RCA in???? So, I assumed…. Are there instructions to get the SPDIF or better I2S out? How would it physically get out??

 

The supplier told me untruths, when I spoken to them yesterday afternoon…the board is coming from overseas as there are none in the country. So, I must wait.

 

In the meantime, I can load both (above) software’s onto my PC.

 

Do I need anything else???

Let me clarify a bit more.

 

The STM32F769i hardware that you've purchased does indeed support SPDIF and I2S. However, the reference software package that we provide (what I've been referring to as our BSP) does not enable these interfaces by default on this target. So to use our tools and the I2S or SPDIF interfaces on the STM32F769i, you would have to update and rebuild the software to enable the interfaces and route the audio as needed.

You can also look at the target's user guide and read about the supported audio topology. Perhaps the default software will meet your needs.
