查看“Joystick Shield拓展板”的源代码

<br />

====一、Joystick Shield====

=====1. 图示：=====

[[File:11.jpg]]

=====2. 价格：=====
11~27元

====二、接口====

=====1. 插板式=====
由于这块拓展板比较大，所以板子设计成可以直接插在Arduino上，除了几个端口被拓展板使用以外，其他引脚插口都可以正常当成Arduino引脚被使用。

=====2. 连线式=====
如果要将拓展板分离，独立连线，最少需要10根杜邦线。

6根控制6个按键，是数字引脚(D)；2根控制遥杆，是模拟引脚(A)；1根电源线和1根地线。

*电源3.3V或5V可以选其一，也可以都连接，然后在左下角的拨码开关处进行选择。

===== 3.[[NRF24L01]]接口 arduino =====
CE_PIN  9

CSN_PIN 10

====三、驱动程序====

=====1. 遥感控制=====
引脚选择：

X值接A0口

Y值接A1口
 #define PIN_ANALOG_X 0
 #define PIN_ANALOG_Y 1
 void setup() {
  Serial.begin(9600);
 }
 
 void loop() {
  Serial.print("x: ");
  Serial.println(analogRead(PIN_ANALOG_X));
  Serial.print("y: ");
  Serial.println(analogRead(PIN_ANALOG_Y));
  delay(500);
 }
<br />

=====2. 按键控制=====
引脚选择：

A接D2

B接B3

C接D5

D接D4

E接D6

F接D7

 #define BUTTON_RIGHT 3
