Question

我有一段时间没有上堆，所以我为此做了一次极端分析，社区一直帮助我，并且真的要首先感谢所有人。

我遇到了一个arduino项目的问题我试图让arduino make rgb灯在用户输入时以不同的颜色亮起。这听起来很基本但不幸的是，arduino在某些情况下不会这样做，或者从用户接收输入的速度很慢。

我无法弄清楚代码或arduino是否存在问题。

以下是我认为问题的代码，当尝试此菜单命令执行一次但不会丢弃循环并将我扔回主菜单。

请注意，代码实际上非常长，所以这只是它的一小部分，完整的代码如下所示。

（FIY ARDUINO UNO R3 ATMEGA 328）

  if(mode == "Party" || mode == "party" || mode == "Party mode" || mode == "party mode" || mode == "Party Mode" || mode == "party Mode" || mode == "c"){
    Serial.println("Party mode");
    Serial.println("For selecting another mode and go back please type back");
  int y;

  int w;
  Serial.println("How many times? note: 1 time = 20 seconds");
while(Serial.available()==0){
  direct = Serial.readString();

  if(direct == "Back" || direct == "back" ){
    break;
  }

  y = 0;
  w = Serial.parseInt();

 if(y <= w){ 

for(int i = 0; i < w; i = i+1){
  Serial.println("Initializing");
  Serial.println(w);

Answer 1

我对你的代码非常慢（对于usart命令）并不感到惊讶。那里有很多延误。每次通过循环都需要短暂的延迟。例如，如果您想要快速响应，请使用状态机。

一些问题：

格式错误
while (Serial.available() == 0)非常奇怪。如果有可用的数据，它将始终跳过整个循环。

评论：

    // wait for 30 milliseconds to see the dimming effect
    delay(60000);

不是30ms而是60000ms（60s）

Serial.print的许多常量字符串。您可以使用F（＆＃34;某些flash字符串＆＃34;）帮助程序将这些字符串仅存储在闪存中（否则它必须复制到RAM中并从中显示）

如果你在＆＃34;小时＆＃34;中检查和处理命令。（比喻说），很快就会很快＆＃34;。

可以使用这样的东西（它只是简短的草图）：

// prototypes:
uint32_t  main_menu_fsm(byte & state);
uint32_t  mode_menu_fsm(byte & state);
uint32_t   off_mode_fsm(byte & state);
uint32_t relax_mode_fsm(byte & state);

// global variables for FSM
byte                         glob_state = 0;
uint32_t                     next_check = 0;
uint32_t (*state_machine)(byte & state) = &main_menu_fsm;

#define SET_FSM(fsm) Serial.println("Setting: " #fsm); glob_state=0; next_check=0; state_machine = &fsm


// global variables for Serial processing
String inputString = "";         // a string to hold incoming data

// RGBLed class
template <byte PinR, byte PinG, byte PinB>
class RGBLed {
  public:
    void begin(byte r = 0, byte g = 0, byte b = 0) {
      pinMode(PinR, OUTPUT);
      pinMode(PinG, OUTPUT);
      pinMode(PinB, OUTPUT);
      set(r,g,b);
    }

    void set(byte r = 0, byte g = 0, byte b = 0) {
      analogWrite(PinR, r);
      analogWrite(PinG, g);
      analogWrite(PinB, b);
    }
};
