PART3 - Drawing Random Eyes Using Ardunio_GFX_Library With 2xGC9A01 and RP2040-zero

In addition to the code shared in Part 1, I will be providing a new example.

To draw an eye shape using the Arduino_GFX_Library, follow these steps:

1. Install the Ardunio_GFX_Library
2. Set up the hardware, including connecting an two GC9A01and sound sensor

Complete the connections. Install the library.

The code creates an eye drawing using given angle and color variables and includes functionality to stop the drawing when a signal is received from a sound sensor. This integration of the sound sensor with the Arduino_GFX_Library allows for interactive control, ensuring that the eye drawing pauses or stops based on auditory input.

here is my sample;

---------------

#include <Arduino_GFX_Library.h>

#include <Arduino.h>

#include "hardware/adc.h"

Arduino_DataBus *bus = new Arduino_RPiPicoSPI(8 /* DC */, 9 /* CS */, 10 /* SCK */, 11 /* MOSI */, 12 /* MISO */, spi1 /* spi */);

Arduino_GFX *gfx = new Arduino_GC9A01(bus, 28 /* RST */, 0 /* rotation */, true /* IPS */, 240 /* width */, 240 /* height */);

// İkinci ekran tanımlamaları

Arduino_DataBus *bus2 = new Arduino_RPiPicoSPI(12 /* DC */, 14 /* CS */, 10 /* SCK */, 11 /* MOSI */, 17 /* MISO */, spi1 /* spi */);

Arduino_GFX *gfx2 = new Arduino_GC9A01(bus2, 29 /* RST */, 0 /* rotation */, true /* IPS */, 240 /* width */, 240 /* height */);
