Basic drawing functions are provided here. In the above part, we describe about the tree structures of linux codes, here we talk about the testing code for user. For example, if you want to test 7. Supports python2.

Because Arduino doesn't have full RAM for display dynamatic image, we don't provide other functions for it. If you want to use Arduino, we recommend you to use Waveshare e-paper Sheild.
