Here is a #MiniDexed IO board for a @raspberry_pi V1 Model B.

And my @raspberry_pi Pico #MiniDexed #TX816 IO panel is now complete.
Or complete enough for me to leave it alone and just have some fun with it now!

So here is a 80s FM Synth style version of my #LoFiOrchestra Jupiter from Holst's Planets Suite.

I've now posted details of the latest version (and the version I'll be leaving alone now) of my TX816 panel IO code.

Full details and a short demo video here: https://diyelectromusic.wordpress.com/2023/02/24/minidexed-tx816-part-6-pico-midi-router-and-tx816-io-code/

#TX816 #MiniDexed #RaspberryPiPico

Another "work in progress" video. This is now routing MIDI in a simplistic way, and will allow me to select voices per tone generator.

I can start to get a feel for how it might work now.

Here, have some DX7 "Jupiter" :)

Update: Final assembly complete (the post has been updated).

Working:
* MiniDexed, display
* Simple MIDI routing
* Audio output
* All panel IO

Not working: I've broken the encoder!

Not started yet:
* Code to make the IO panel useful for MiniDexed!

That will take some time!

Right, I've written up everything I have so far.

The latest posts include the two build guides for the PCBs and the mechanicals so far to get to the point of testing the integration of all the IO and the Pico.

Latest work in progress.

I'm starting to get somewhere with a Pico now able to drive all the IO for my TX816-style panel for my MiniDexed.

Note: No Raspberry Pi or MiniDexed on it yet. This is just LEDs, pots and switches at the moment.

(linked video shows the LEDS and 7-seg displays working with switches and pots, behind a black TX816 style panel)

And that is everything I have so far - that is all the theory...

Now I have the boards back from Seeed Fusion its time to start populating them to see if any of this has any chance of actually working!

But that will have a wait for a bit now.

And in part 3, I've detailed how I put a panel together for everything.

Here is part 2, which looks at the PCB design I've gone for.

I'm starting to think about how I might make a TX816 styled front panel for my MiniDexed.

The first part describes the background context and thinking so far.

I'm thinking about doing a RPi V1 (i.e. the 26-way header one) MiniDexed IO Board...
