Have you had a look see here?
Getting Started with Interstate 75
And have you edited your file for your panel setup?
interstate75/docs/README.md at main · pimoroni/interstate75
from interstate75 import Interstate75, DISPLAY_INTERSTATE75_128x32
i75 = Interstate75(display=DISPLAY_INTERSTATE75_128X64)
Yes I have tried following those pages , I’ve tried different settings such as the 64x64 and 128x64 and 128x128 my understanding is that if those settings are wrong I’d still get an output on the panel of something. At this point I can’t get anything on the panel , I’ve even tried the PANEL_FM6126A but can’t even get a pixel to flicker.
Could you please post a link to the panel your using?
Also, a picture of your setup might help? The back of the panel with the i75 plugged in etc.
What are you using to power it all?
EDIT: I have interstate 75w, the older Pico W (RP2040) onboard. Which one do you have and what uf2 did you flash it with?
I’m not in front of the panel right now , I’ll upload a pic in the morning , it’s the 2530 or 2350w ? I uploaded the same firmware with the test files and none of the start files load on it.
Power wise I’ve used my pc, usbc power bank and also a usbc charger .
I’ve checked for continuity between the i75 and the board and checked the voltage for 5v on the board as well.
Ok, so you used the i75w_rp2350-v0.0.5-micropython-with-filesystem.uf2
That’s the one I got from the release page
So further digging with the schematics means I need to build a breakout board for this panel to begin working .
Are there any markings on the back of the panel denoting which plug is Data In and Data Out?
Not that I’m aware of I’ve tried both sides , I’ve also done continuity checks and seen that both sides are linked together so I don’t think this panel minds
I have two 64x32 panels physically orientated as 64x64. Mine are marked data_in and data_out which is why I asked. Electronically / code wise they are 128x32.
from interstate75 import Interstate75
from interstate75 import Interstate75, SWITCH_A, SWITCH_B
i75 = Interstate75(display=Interstate75.DISPLAY_INTERSTATE75_128X32)
I’m running older code with an older uf2 though. Mine is RP2040.
Posting your code might help?

I’m having the same issue with my 128×64 panel it only has A, B, C address lines, but the Interstate 75W firmware seems to expect A–E. I tried adjusting the panel type and firmware settings, but no luck. Has anyone actually gotten a 128×64 (A–C) panel working with the Interstate 75W. kindly share me what should i do.
