Yes, supply checked, currently on 3.3 but tried 4.0 too. Address change is next I guess....

Changed address, no change other than it no longer works with my arduino. It must be something really simple.....
Odd...
And changed it back again and it still works with the arduino.

Gareth,

I may be reading the messages wrong but I think you are now running v0.8 of Minitioune. I wonder which software you have in your FTDI module as I read somewhere that v0.8 only works with the original FTDI firmware. Have you fitted the resistor the v0.8 software looks for? I have the digole TFT fitted to my minitioner and have found that the minitiouner needs to be powered up before being plugged into the laptop otherwise the TFT doesn't work, not sure if the OLED is the same? Probably been through all this I bet.

Good luck. Dave.
...are you sure I can't use a pair of 813's?... :shock:

My oled display worked with both the original ftdi chip settings and the modified ftdi chip settings with v0.8. I left it at the original settings for future compatibility (ie lest i forgot!)

OK, I've done the resistor mod and MT0.8 works fine, yes that's what I'm running. I don't THINK I changed the FTDI code from what it came with so its original BATC as supplied in there. I can't find any reference to a need/method of updating the USB anywhere (yet).
Running "Testmy MT v2.0" shows I2C performance and NIM testing as OK, but neither Test OLED 1 Master or TestOLED2 Master show on the display, saying SSD1306 NOT OK.
So for some reason, its clearly not talking to my display module (which works fine on an arduino sketch).
I'm puzzled, still....

Not sure if I've spotted the problem or just a typo...

You said, "...so I have returned that to 0."

The line should read "Digole=no"

Hopefully it's something as simple as that. I struggled for ages with the Digole as there is a set of 3 tiny pads which have to be shorted one way to select serial or the other way to select I2C, took me ages to work that out.

Hi Dave, I've re-read the guidance, from the way its laid out in the config file I think it should be 0. But I have tried both, 'no' and '0', neither work.
I'm still mystified, its only 4 wires and a working module.....that's not working....
Clearly its not getting the data it needs to show anything, but I'm lost at this point. I'll revisit tomorrow perhaps.

Your OLED looks different to those Dave and I have. Perhaps it is not compatible with the current software?

Mike, Yes, that's possible although I have displays from two different vendors that appear identical. From my 'rapidly growing' understanding of I2C devices, each should have a unique address so either 'industry' decided to default all these OLED displays to one, maybe 2 (as in my case, selected by a 4K7 jumper) Ican but assume that MT v0.8 has that address hard-coded somewhere and enabling OLED=YES implements that code.

I'll post my question up on VivaDATV too and see if anything comes from that.

It must just need a correct address setting in software, this sample line from an arduino sketch "LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3); // Set the LCD I2C address"

Failing that, could you share where you got your display from and perhaps a picture of the rear so I can compare?
Thanks
Gareth

**update** found some arduino based display usage that suggests the need to ID the I2C address of displays, so I think this is certainly my issue.

This I2C Scanner for Arduino will help you verify the I2C address. It tests all addresses and displays the result using the serial monitor tool that's part of the Arduino software.
