Hi @guhland Good news that I implemented rotate method for 1-bit displays. ```.cpp NanoCanvas canvas; NanoCanvas rotatedCanvas; void setup() { /* Initialize and clear display */ display.begin(); display.clear(); canvas.setMode( CANVAS_MODE_TRANSPARENT...

Hi It would be nice to have full sketch example (as simple as possible), that doesn't work in your case. So I can run tests and figure out what's wrong.

Hi, I slightly modified your example to run in Arduino IDE. Please, find my comments below ```.cpp #include "lcdgfx.h" DisplaySH1107_64x128_I2C display(-1,{-1, 0x3C, -1, -1 , 0}); NanoCanvas canvas; //

This is how it looks like if to run the example provided by you:  This is how the display looks like, if to apply my recommendations:  If the...

Hi, please try to comment out the lines in [src/ssd1306_hal/arduino/io.h](https://github.com/lexus2k/ssd1306/blob/master/src/ssd1306_hal/arduino/io.h) source code: ```.cpp #include #include //#elif defined(ARDUINO_ARCH_SAMD) //#include //#include #else #include #include #endif ``` Let me know what it gives...

By the way, what's is the version of board support package for SAMD controllers?

Board support package version is not the same thing as Arduino IDE version. Arduino IDE has built-in manager as you know, where you can install support packages for different hardware....

It would be nice, if someone has the fix already. If not, then the problem will be fixed, when I have the time. The library is free.

My compilation passes for ESP8266:
