3.2.3 Code Example
Here we will explain how to use a code example of the U8g2 library.
We will use the example
GraphicsTest
.
This example can be found under

U8g2
→
full_buffer
→
GraphicsTest
. In this code, you need to uncomment
line 160 before you can execute it using the Upload button.
This is because line 160 contains the declaration of the display
using 8080. Of course, you can use the other examples in the same
way by uncommenting the same line in the other code
examples.
Note that under
Tools
, Board and Port must be correctly selected.
