I borrowed the BIT MAP data from [here](https://www.mischianti.org/2021/07/14/ssd1306-oled-display-draw-images-splash-and-animations-2/).
__Wire cables should be as short as possible.__
__Flip upside down cannot be enabled.__
I used a 10 cm wire cable.
However, it is sometimes affected by noise.
__Flip upside down cannot be enabled.__
The SPI interface operates faster than the I2C interface.
For SPI interfaces, there has a latency period between frames.
By making this smaller, you can display it even faster.
