Amazing project

[alros100]

Hi
I have been looking for a solution for control of ToneX one. Amazing!

Questions:
I have three esp32-S3 wroom development boards hanging around. Would they work or only the waveshare S3 zero/ mini boards?

I will start with one, but I am also hoping to build two with direct midi wiring so i can run two amp/ cabs at same time from left and right send / receive loops and just change the presets .

Is the direct midi firmware up already ?

Thanks so much!

Hi Al. You'll need to check the schematic of those boards, and see if they support USB host. Have a look at the power circuit, and see if it allows 5v to be connected somewhere other than the USB port, and if that voltage does also go to the USB port.
Most of the Waveshare boards are OK here, where some of the boards like from Seeed Studio are not OK (diode blocks power.)

If the above is OK, then the other factor is how much flash and PSRAM. There are lots of different variants.
The Zero board is 4 MB flash, quad interface, and quad mode PSRAM.
The 4.3B is 8 MB flash, octal interface, and octal interface PSRAM.

If you run a pre-built release, and any of these settings don't match yours, it will crash on boot. If you can compile the code however, then its not too difficult to change the settings to match.

Regarding wired Midi, the pre-built releases 1.0.3.2 don't support it, but I hope to have it finished in the next few days. Its already working well on the Zero and the 1.69 board. Just need to get the 4.3B finished.

Hi Builty

Just wanted to report that I fully set up the 169 board with external midi and the foot switch and it works perfectly ! I tested midi control with both an FM9 and GT-1000

Thanks so much! Donated for the cause.

The only thing I noticed is some noise/ chatter from the 169's onboard buzzer.

Great, thank you.
Another user has reported some noise from the buzzer also. Does your PCB have a "V2" sticker on the USB-C port?

[alros100]

Hi

No sticker on mine. I can't see a version code elsewhere. I got it off Amazon. Here is a picture.

Ps. I put a little precautionary heat sink on the S3 as it seemed a little hot.

[Builty]

OK so its a V1, makes sense. I've got a tech support request in with Waveshare about options to fix this.

Could you try blocking this little hole shown below, and see how much quieter that makes it?
