SSD1306 is displaying nothing #62

Hello,

probably I'm doing something wrong or I didn't understand the usage of this library properly. I have a SSD1306 128x64 display. My ATtiny85 has a Bootloader set to 8 MHz. I use the ATtinyCore from Spencer Conde with the Optiboot option to program the Attiny. When I upload one of your test sketches (from the Github site here or from the examples in the Arduino IDE) there is no output on the display. I normally use the TinyWireM library from Adafruit.

It could be that the SSD1306 has remembered some settings stopping it from working> This Tiny4kOLED library uses a minimal setup routine, which assumes the SSD1306 starts with its default values. If this is the case, you could try installing and running the "ResetToDefaults" example?

No, unfortunately it isn't showing nothing is this case as well. But the display is ok, I have another ATtiny project laying around here and as soon as I put it in here it shows the expected values. Here is the link to the code: https://github.com/SensorsIot/BatteryTesterAttiny

Ok, solved. It had something to do with my self built programmer :)
