SD cards init at 200-400KHz. sd.begin(CS_PIN) will switch to the highest SPI speed supported by the board that is less or equal to 50MHz. For Uno that is 8 MHz....

Modern cards are far more complex than the 512 byte sector model. Cards emulate 512 byte sectors with very large flash pages called Record Units. The RU size for class...

I will add this in a future release. I limit the number of releases since the Arduino Library Manager nags users to update libraries.

This will appear in the next release together with other mods. I now have more than one version of the 64x32 0.49 inch display submitted plus other mods to test.

None of your pull requests will be applied since I have a private beta. It may be a few months until I post mods I have made to the beta....

I probably should have a beta version of this library. It is amazing how often simple mods break apps for users. Today I found that this fails on many "Arduino...

I will Add this. Also on horizontal bar graphs, you can use: `void ssd1306WriteRamBuf(uint8_t c);`

Your SH1107 mod may not work. The reason for the mask of 7 was not the display height but the memory pages in the SSD1306. The SSD1306 has a 128x64...

I tried the horizontal bar graph like this for 50 pixels long. I added this loop the Hello World: ``` oled.print("Hello world!"); // Test bar graph oled.println(); for (uint8_t i...

I have no idea what is happening.
