我有一个程序可以读取Arduino UNO的Digital PINS。默认情况下，我已使用“ PULLUP”关键字打开了所有的Digital PINS。现在，如果我将“跳线”插入任何数字PIN，则为PULLDOWN（关键字）。我在间隔0.5毫秒后连续读取数字PINS的状态（此时间间隔在Arduino IDE中进行了编码），它会给我“ 1”和“ 0”，如果将跳线插入任何数字PIN中，它将给出“ 0” ”，否则它将为“ 1”。
然后将“ 0”和“ 1”存储在数字PINS的两个数组中，即“用于保持先前状态的预数据，用于保持当前状态的新数据”，并在GUI屏幕上显示状态。
首次运行Arduino UNO时，“ newdata”和“ predata”相同。然后，我有一个无限While循环，该循环连续读取Digital PINS并将其存储在“ curdata”数组中，并将其与“ predata”数组进行比较。如果“ predata”和“ curdata”数组不匹配，它将存储“ curdata”数组的所有值写入“ predata”并在GUI屏幕上显示。
除此if语句外，所有代码均正常运行，未在执行。由于这个原因，程序卡住了：
if (curdata[a7] != predata[a7]):
predata[a7]=curdata[a7]
oldstatus()
newstatus()
