# MeterDemo for SSD1306
|
||||
|
||||
|
||||
|
||||
I borrowed the BIT MAP data from [here](https://forum.arduino.cc/t/analog-vu-meter-i2c-oled-sh1106-oledmeter-animation/388374).
|
||||
|
||||
|
||||
|
||||
This sample shows how to quickly redraw a BITMAP image.
|
||||
High-speed drawing is possible by converting BITMAP data to Page and Segment.
