So, I finally got my OLED display (see pictures attached). I connected the SCL pin of the display to C.1 (hi2 scl) on my 08M2 picaxe and the SDA pin of the display to C.2 (hi2c sda). Using the code found in this threat (https://bit.ly/2v9ztdm) - which I will also attach below - I tried running...

Thanks thanks! As mention in my I2C backpack post, I'm moving onto a proper OLED I2C display. But don´t worry, I'm keeping all of this in case I decide to come back to the LCD.

Thanks a lot for all the help Hippy! Unfortunately, it seems like this solution (an I2C backpack) is a bit too complex for my project. I've ordered myself a new I2C OLED display which should hopefully be easier to set-up. I'll let the forum know if I have any problems with it!

Thanks for the help everyone. I'll post a new threat with everything in detail, just need to run a few more tests first.

It's a little bit more complicated than what you think, but good point; will post the entire problem with all that!

Did that, but still failing to connect...

Right, think I might have forgotten to do this:

Aka, this is correct, right?

What is the baud rate for programming the 20M2? Found a 10 year old threat that sais 4800, but considering the age (and the fact that my contraption is not working), I'd just like to double check.

One remark... this only seems to work for/control lines 1 and 3 of the display. Is there any way to get control of all four lines?

Nevermind, got it! serout C.2,N2400,(254,1) ;clear display

IT WORKS!!! Reprogrammed the firmware and it did nothing, but then noticed the part about ; Note you must uncomment just one of these two options ; depending on whether you have an LCD or OLED module #define use_OLED ;define use_LCD So I changed it to ; Note you must uncomment just one of...

Checked, the voltage is the same.

I have no idea... how do I check?

Thanks! It all sounds and looks very complicated though... might end up buying a dedicated I2C display if it really is, we'll see...

I am using an I2C adapter from AZ-delivery. Here is a link for the datasheet (https://bit.ly/380yCZR) and the thing itself (https://bit.ly/3agkJs7).

Think I used the wrong slave address - changed it to $4E thanks to someone's kind explanation in my I2C Adress post. But it still doesn't work.

Used an I2C display this time (well, it's really a regular one with an I2C adapter). Connected the SDA output to the SDA pin, the SDC output to the SDC pin, power to where it should be aand what do you know, it doesn't work. Code copied exactly from axe033 manual.

Since the screen goes from all empty to all black squares when I turn it, I'd say yes.

I have, that's the orange knob hanging off of the thing in my second picture... but thanks for the effort!
