Introduction: 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:
- Install the Ardunio_GFX_Library
- Set up the hardware, including connecting an two GC9A01and sound sensor
Supplies
Step 1:
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 */);
