Congratulations, it looks great. Do you aim to share the stl file for your
box?
Thx! Richard

Awesome project…what plastic did you use for the printed box? Thanks

Here you go :) |

Very nice! And thanks for sharing your files with the community. |
Okay, so can Pedalino connect directly to the widimaster, or only via another device? Thanks, |
When I am using my setup in "gig" mode I have the following
When I power it all on, it connects without further intervention. The Pedalino box starts up quicker than the Stomp. The MIDI BLE on the Pedalino talks directly to the WIDIMaster, which then passes the MIDI to the HX stomp (MIDI also travels from Stomp thru WIDIMaster to the Pedalino), the only other things I need are in my sound chain (Guitar/cables/amp/cab) 🎸 🔈 😄 |
Very nice! Thanks for the explanation. |
Hi Samantha, you could possibly do without the multiplexer, take a look at this: https://github.com/bitbank2/Multi_OLED I have done something similar with cheap chinese colour SPI displays and the TFT_eSPI library, but that won't work with Pedalino I think. |
Did you ever manage to get the multi displays working? Very interested. |
I never did as I got sidetracked with another project (patchbox OS based
multi effects, it can run the OSS that Moddevices use on their Dwarf and
other pedals). I had intended to go down this kind of route (
https://github.com/bitbank2/Multi_OLED).
Sadly all my possessions were destroyed in a home fire a couple of weeks
ago so it’s going to be some time before I can even consider trying it out.

I'm also building one to use with an HX Stomp!

Oh no! That's so sad! Did you loose your instruments and pedals too? |
Sadly yes, including a bass I’d hand built and the wood/bits for the second
hand build. I focus on the fact that I survived and no one got hurt!

I've just finished making one of these :)
It is based on an AZ Delivery WROOM-32 Dev Kit v4 board, which I added to my platformio.ini
the only issue I've run into is that to flash the firmware or attach to the monitor, one needs to hold the boot button on the wroom board to tell it to listen. I read somewhere that by soldering a small cap in place this can be avoided, not tried it yet.
I found I could not initially build the firmware, seeing the following error:
I found that pinning the NimBLE-Arduino library to version 1.3.7 resolved this.
I changed
https://github.com/alf45tar/PedalinoMini/blob/master/platformio.ini#L141
to
https://github.com/h2zero/NimBLE-Arduino/archive/refs/tags/1.3.7.zip
I decided I wanted 8 'digital' switches (and did not want to use pull down resistors) so I modified the pedal configuration for this board; I don't intend to use analog so I 'stole' GPIO_NUM_32 & GPIO_NUM_33
Seems to work OK.
But what does it LOOK like!?

And those extra windows!?!?

I want to have a scribble strip for each footswitch, so I've left space to position an OLED display between pairs of switches.
I'm aiming for something like this
I aim to use a multiplexer to resolve the I2C addressing issue.
https://learn.adafruit.com/adafruit-tca9548a-1-to-8-i2c-multiplexer-breakout/overview
explains how.
I just need to wrap my head around the OLED display code to support this and modify it accordingly; then wire in the multiplexer and additional OLED display panels.
