public async Task InitializeAsync();

/// <summary>

public async Task Print(string value);

/// <summary>

/// </summary>
/// <param name="x">From 0 to 15</param>

public void Dispose();

How to Use

• First, you need to create a LCD1602 object. After that you should call InitializeAsync() to initialize.

LCD1602 lcd = new LCD1602(18, 23, 24, /*4, 17, 27, 22,*/ 5, 6, 13, 26);
await lcd.InitializeAsync();

• Secondly

await lcd.Print("Hello World!");
await lcd.SetCursor(9, 1);
await lcd.Print("--Zhang");

• If you want to close the sensor, call Dispose().

lcd.Dispose();
