当我在代码中添加delay(timer)时，编译器抛出一个错误，timer是在代码开头定义的常量整数。
当我注解掉延迟线时，编译器成功完成。
倒数第四行

// Include RadioHead Amplitude Shift Keying Library
#include <RH_ASK.h>
// Include dependant SPI Library 
#include <SPI.h> 

// Create Amplitude Shift Keying Object
RH_ASK rf_driver;

const int BLUE = 3;     // the number of the pushbutton pin
const int GREEN = 4;      // the number of the LED pin
const int RED = 5;      // the number of the LED pin
const int thisPin = 4;
const int timer = 100;

// the setup function runs once when you press reset or power the board
void setup() {
  // Initialize ASK Object
  rf_driver.init();
  Serial.begin(9600);
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(RED, OUTPUT);
  pinMode(GREEN, OUTPUT);
  pinMode(BLUE, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
    int mesg = 0;
    // Set buffer to size of expected message
    uint8_t buf[8];
    uint8_t buflen = sizeof(buf);
    if (rf_driver.recv(buf, &buflen)) {
      // Message received with valid checksum
      Serial.print("Message Received: ");
      Serial.println((char*)buf);     
      mesg = 1;
    }
    if (mesg == 1) {
      mesg = 0;
      digitalWrite(thisPin, HIGH);
      //delay(timer);
      digitalWrite(thisPin, LOW);
    }
}

下面是错误消息：
