测试Arduino nano 168p-注意处理器的选择

2022-12-08
相比于uno, 2560, 这个小不点更加可爱。

自己用的这款是这样的：

1.下载blink程序，比较顺利就测试成功。

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO 
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino model, check
  the Technical Specs of your board  at https://www.arduino.cc/en/Main/Products
  
  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN,LOW);    // turn the LED off by making the voltage LOW
  delay(200);                       // wait for a second
}

上传前必须地选择相应的型号、端口号。但芯片型号也是其中之一。因为对于nano这个型号来说，有两种芯片型号：ATmega168和ATmega328。

前边之所以说比较顺利 ，是因为最初测试时，没有选择处理器。默认是328，而出现了错误。
