Tried to resolve the conflict from network branch.

Build for testing:

Use at your own risk.

Hello Omersiar,
I'm happy to read that there may soon be a network function for the miniDexed.
How do I configure the network on the Raspberry Pi?
What should I test with version 2024_11_08_fc85a46? Have I missed any instructions?

Regards
Peter

Hi,

https://github.com/omersiar/MiniDexed/releases/tag/v0.0.1

Please also follow the instruction there. mt32's wiki has useful information too.

I'm sure you have pretty decent setup, so you can send midi notes for all your tracks to see if it can keep up, the implementation does not take into account the timestamps so notes can arrive late or early.

I mostly wanted to have it to test and tune sounds but full track playback should be the ultimate goal i think

Thanks @omersiar, I will try it very soon. This is really cool.

The way I understand it, according to https://github.com/rsta2/circle/tree/master/addon/wlan/sample/hello_wlan, this might work with the on-board WLAN device of the Raspberry Pi 3, 4, 5 and Zero W (not sure about the Zero 2).

A /firmware directory must be created on the SD card and firmware files for the WLAN modules need to be put in there. I'll try to do this as part of the build process so that users won't have to think about this.

Furthermore a configuration file wpa_supplicant.conf is required in the root
directory of the SD card. Please don't forget to edit your WLAN configuration in this file.

In minidexed.ini we need

# Network
NetworkEnabled=1
NetworkDHCP=1
NetworkType=wifi

Most likely we should ship it by default as

# Network
NetworkEnabled=0
NetworkDHCP=1
NetworkType=wifi

and instruct users to change NetworkEnabled to 1 if they want to use it.

Merged into a separate branch so that I can work on it; continues in #747.

/firmware files are propriety blobs which they may not allowed to redistribute freely.

This fashion is more correct I think

That's what I am using; let's continue in #747.
