【中文标题】如何在 blynk (arduino) 中合并 2 个文件【英文标题】：How to combine 2 file in blynk (arduino) 【发布时间】：2019-10-07 12:22:53 【问题描述】：我有 2 个草图，一个是我的 led 运行的代码，另一个是 blynk 连接代码，我想结合这 2 个草图，以确保我可以连接到我的 blynk 应用程序并让我的 led代码运行。我使用 esp 8266 wifi sheild 连接到我的手机应用程序，因为我用完了我的 arduino 的所有引脚
blynk 连接代码
#define BLYNK_PRINT Serial
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "ghznMVLIilXc08bYkO9qyNl_A6KaY7kT";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "find yr own one";//store ssid user name
char pass[] = "yashwini123";//store password
// Hardware Serial on Mega, Leonardo, Micro...
//#define EspSerial Serial1
// or Software Serial on Uno, Nano...
#include <SoftwareSerial.h>
SoftwareSerial EspSerial(2, 3); // RX, TX
// Your ESP8266 baud rate:
#define ESP8266_BAUD 9600 // set to 9600
ESP8266 wifi(&EspSerial);
void setup()
// Debug console
Serial.begin(9600);
delay(10);
// Set ESP8266 baud rate
EspSerial.begin(ESP8266_BAUD);
delay(10);
Blynk.begin(auth, wifi, ssid, pass);
void loop()
Blynk.run();

【问题讨论】：
不清楚第一个文件的代码在哪里结束，第二个文件的代码从哪里开始。两个代码部分都包含在帖子中吗？上面的代码部分中真的有C, C++ & Java吗？如果是这样，请编辑您的帖子并将它们分开。
在 single projects combining Java and C++ 上的讨论。
【参考方案1】：
理论上你必须结合两个项目/草图的setup()和loop()功能。
在您的情况下，这有点困难，因为您的 LED 项目的 loop() 函数在 loop() 和 loop() 调用的函数中都包含对 delay 的调用。
您必须确保在执行 LED 操作时经常调用 Blynk.run();。因此，您可能必须重构 LED 项目的 loop() 函数以及从中调用的所有包含 delay 调用的函数，否则需要很长时间才能运行。
另请参阅http://help.blynk.cc/en/articles/2091699-keep-your-void-loop-cleanhttps://dzone.com/articles/arduino-using-millis-instead-of-delay
作为一个简单的技巧，您可以将所有对 delay(x) 的调用替换为 delayWithBlynk(x) 并使用类似的函数
void delayWithBlynk(unsigned long delay)
unsigned long time_now; // for current time in loop
unsigned long time_start = millis(); // start time of intended delay
do
Blynk.run();
time_now = millis(); // current time
while(time_now - time_start < delay); // repeat if delay time has not passed yet
这个想法是每当 LED 功能的执行必须等待延迟时重复调用Blynk.run()。 （此代码/解决方案未经测试。）
更好的解决方案是重构所有函数以在固定周期内重复调用，例如每毫秒一次或每 10 毫秒一次，并在内部处理它们的时间和状态。
想法：从loop() 调用的所有函数（turnEverythingOff() 等）通过它们的返回值指示它们是否需要再次调用或任务是否完成。在loop() 中，您保留一个状态，指示现在必须调用哪个从属函数。这个函数将被重复调用，直到它发出它完成任务的信号。然后状态将切换到下一个函数，该函数将在下一个循环中调用，等等。
