SPI/I2C OLED display

Hi! My first attempt at using a OLED on the Axoloti:

Hey everyone!

So cant wait any longer on getting some OLED's. Axo nr 3 arriving shortly I need to get some visual feedback from each device. Many of the links above are dead by now, but I think I found something that should work:

Can anyone confirm that I can use 2 of these with @SmashedTransistors tiar/HW/OLED128x64Dbl object?

I also see I need to get some pull up resistors. Any specific ones I need to get?

Thats all right?

Thanks

I used one of those:

I didn't use resistors...

@Latzenpratz

Thak you for the tips. yeah I am going for the 1.3" ones. And half price from the ones I found Are you using 2 of them connected to a single Axoloti?

You didnt use resistors and it just worked? Awesome I am scared of breaking stuff, so the less I have to touch, the better

lokki 2018-04-26 14:46:41 UTC #86

as pointed out by @SmashedTransistors in his oled thread i think you should use resistors because you potentially can break things if you don't. this is because the state of the used outputs is not always well defined (upon patch-start, or when changing patches). the resistors are there as a security measure as well...

so it will work, may work for a long time, but to be safe add the resistors.

@lokki

I ll take a look at it... But resistors etc. is not something I have lying around here. Could you recommend one?

Thanks

Just use any 10k resistor, one connected from pb8 to vcc and one from pb9 to vcc.
By the way, here's the patch i used (and the mux10 object):

Cool thank you foe the patch, Ill check it out

I found this in a local store, which I am oging to try then:

Just buy a cheap set:
