# How to Use # How to Use
Below is a bare minimum sketch to draw a single white dot in the top left. You MUST call .begin() before you call ANY other function of the RGB64x32MatrixPanel_I2S_DMA class! Below is a bare minimum sketch to draw a single white dot in the top left. You must call .begin() before you call ANY pixel-drawing (fonts, lines, colours etc.) function of the RGB64x32MatrixPanel_I2S_DMA class.
No call to .begin() before use = Crash No .begin() before other functions = Crash
``` ```
#include <ESP32-RGB64x32MatrixPanel-I2S-DMA.h> #include <ESP32-RGB64x32MatrixPanel-I2S-DMA.h>
RGB64x32MatrixPanel_I2S_DMA matrix; RGB64x32MatrixPanel_I2S_DMA matrix;
