将“int"分配给“int [2]"时的类型不兼容 [英] Incompatible types in assignment of ‘int’ to ‘int [2]’

问题描述

在 Arduino 中我有一个错误.

In Arduino I have an error.

将‘int’赋值给‘int [2]’的类型不兼容

incompatible types in assignment of ‘int’ to ‘int [2]’

long received;
long received_t;
long received_m;
int arra[2];

void setup() {
    analogReference(INTERNAL);
    Serial.begin(9600);  
}

void loop() {
     while( Serial.available() > 0) {
         arra = Serial.read();
         Serial.println(arra[0]);
         Serial.println(arra[1]);
     }
}

推荐答案

怎么样

 while( Serial.available() > 1) {
     arra[0] = Serial.read();
     arra[1] = Serial.read();
     Serial.println(arra[0]);
     Serial.println(arra[1]);
 }

?

仍然不是好的代码，但至少应该编译.

Still not good code, but should at least compile.
