Question

更新：所以我收到错误：“使用此代码在'fsrAnalogPin'之前预期的初始化程序”。有人可以帮我解决这个问题吗？

如果有人可以帮我处理我的代码，我将非常感激。我要做的是：使用一个力敏电阻，我想用一个arduino计算FSR上给定的压力，然后在LED矩阵上显示每个抽头。换句话说，我手上有一个带有FSR的手套，我想计算“拳头颠簸”然后显示在32x32 Adafruit LED矩阵上。

以下是我希望它的样子： https://drive.google.com/file/d/0B4kq-ADrtz4mSzNWUTJoNGlBSU0/view?usp=sharing

这只是底部的静态数字。我需要帮助制作代码将计数变量连接到FSR“颠簸”。它可能很简单，但我对此完全是新手，因此需要学习很多东西。所以任何帮助都表示赞赏

Answer 1

首先，您需要从loop()删除setup()方法。

在void loop()方法中，进行以下更改可以使事情正常进行。

void loop(){
    fsr.read(); 
    if( fsr.wasPressed() ){
        counter = counter + 1
        matrix.setTextColor( matrix.Color333(0,7,7) );
        matrix.print( counter )
    }
}

我还建议遵循适当的缩进。这将使您的代码可读。如果你修改你的Arduino编程也会很棒。概念
