Arduino重置-復位問題

轉自： https://blog.csdn.net/y511374875/article/details/77845240

三種方式手動重啓Arduino

1.Arduino板上從新編寫代碼時，Arduino將從新設置 2.Arduino軟件中打開串行終端，同時將Arduino板鏈接到計算機。打開串行終端時，Arduino會自動重置 3.按下復位按鈕

 

兩種方式自動重啓Arduino

詳情見： https://www.theengineeringprojects.com/2015/10/upload-bootloader-atmega328.html

1.使用Arduino板上的RESET引腳以編程方式從新設置Arduino，就是利用一個數字口，代碼運行到那的時候就將REST置低 這裏利用數字口D2

int Reset = 2;

void setup() {    digitalWrite(Reset, HIGH);   delay(200);   pinMode(Reset, OUTPUT);       Serial.begin(9600);   Serial.println("How to Reset Arduino Programmatically");   delay(200); }

void loop() {   Serial.println("A");   delay(1000);                 Serial.println("B");   delay(1000);                 Serial.println("Now we are Resetting Arduino Programmatically");   Serial.println();   delay(1000);   digitalWrite(Reset, LOW);   Serial.println("Arduino will never reach there.");

2.不使用任何硬件引腳，Arduino有一個名爲resetFunc（）的內置函數，咱們聲明函數地址爲0，當咱們執行此功能時，Arduino將自動重置。

說明： –In this method, we are not gonna use any hardware pin, instead we will do everything in programming. –Arduino has a builtin function named as resetFunc() which we need to declare at address 0 and when we execute this function Arduino gets reset automatically. –So, no need of doing anything in hardware and simply upload the below code in your Arduino board.

 

void(* resetFunc) (void) = 0;

void setup() {       Serial.begin(9600);   Serial.println("How to Reset Arduino Programmatically");   delay(200); }

void loop() {   Serial.println("A");   delay(1000);                 Serial.println("B");   delay(1000);                 Serial.println("Now we are Resetting Arduino Programmatically");   Serial.println();   delay(1000);   resetFunc();   Serial.println("Arrduino will never reach there.");
