# CounterDemo for SSD1306
![CounterDemo](https://user-images.githubusercontent.com/6020549/166628057-fc8c0f7f-7d94-4ffe-8866-d145d953f94d.JPG)
I borrowed the PNG image from [here](https://www.iconspng.com/image/5656/seven-segment-display-gray-0).
__Wire cables should be as short as possible.__
I used a 10 cm wire cable.
However, it is sometimes affected by noise.
# How to create BIT MAP data
- Download PNG image.
- Shrink PNG images below frame size.
- Convert from PNG to BMP data using [this](https://www.mischianti.org/2021/07/14/ssd1306-oled-display-draw-images-splash-and-animations-2/) page.
- Paste the BMP data into your code.
