exception - While 循环使用 ESPNOW 引发异常
问题描述
我一直在做一个项目，我需要在 ESPNOW“dataReceived”函数中有一个 while 循环，这意味着一旦接收到某个 char 数组，它就会激活循环。您只能通过发送另一条不同的消息来跳出循环。但是如果我激活循环（正如您将在代码中看到的，您需要接收“on”然后“customfade”来运行它），它会立即引发异常（见下文）。

在我更深入地进行故障排除之前，我想知道在这种情况下，while 循环是否存在任何主要问题或缺点，即基本上在设置例程内部在 ESPNOW dataReceived 函数中运行。下面是复制异常所需的代码，我在 ESP8266 上运行它。
#include <EEPROM.h>
#include <ESP8266WiFi.h>
#include <espnow.h>
#define red D2
#define green D5
#define blue D1

// Serial.println();

memcpy(&packet, data, sizeof(packet));
Serial.println(packet.request);
if (strcmp(packet.request, "on") == 0) { //on
if (on) {
on = false;
analogWrite(red, 0);
analogWrite(green, 0);
analogWrite(blue, 0);
}
else {
on = true;
analogWrite(red, EEPROM.get(0, redBrightness));
analogWrite(green, EEPROM.get(4, greenBrightness));
analogWrite(blue, EEPROM.get(8, blueBrightness));
}
}
if (strcmp(packet.request, "customfade") == 0) {
int numSteps;
int i = 0;

analogWrite(blue, blueOutput);

break;
Serial.println("received data and broken out");
}

int blueOutput = ((float) blueBrightness / numSteps) * i;
analogWrite(red, redOutput);
analogWrite(green, greenOutput);
analogWrite(blue, blueOutput);

yield();
}
}
}
}
void setup() {
