Question

我正在尝试使用Adafruit 32u4 FONA制作一个简单的设备。只需按一下按钮，系统便会打开并拨打电话。但是出于某种原因，它拒绝打开电源并执行应做的事情。

void PinMode_Setup() {
pinMode(13, OUTPUT);//This is the blinky light
pinMode(6, OUTPUT);//This is the MOSFET gate
digitalWrite(6, HIGH);//Immediately activate the MOSFET gate
}

#include "OneButton.h"
#include "Adafruit_FONA.h"

#define FONA_RX 9
#define FONA_TX 8
#define FONA_RST 4
#define FONA_RI 7

#define Number "##########"

int count=0;//This will count how many times we blink before turning off

// Hardware serial is also possible!
HardwareSerial *fonaSerial = &Serial1;

// Use this for FONA 800 and 808s
Adafruit_FONA fona = Adafruit_FONA(FONA_RST);

uint8_t readline(char *buff, uint8_t maxbuff, uint16_t timeout = 0);

uint8_t type;

void setup() {

   digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); 
   delay(1000); count++; if(count>2) {int count=0;} delay(2);

{
    while (1);


  }
  type = fona.type();
  switch (type) {
    case FONA800L:
      break;
    case FONA800H:
      break;
    case FONA808_V1:
      break;
    case FONA808_V2:
      break;
    case FONA3G_A:
      break;
    case FONA3G_E:
      break;
    default: 
      break;
  }

  pinMode(FONA_RI, INPUT);

  pinMode(LED_BUILTIN, OUTPUT);

    while (1) {

    digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(100);                       // wait for a second
    digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
    delay(100);

    uint8_t n = fona.getNetworkStatus();
    if (n == 0) digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); count++; if(count>1) {int count=0;} delay(2); //Not registered
    if (n == 1) digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); count++; if(count>2) {int count=0;} delay(2); //Registered (Online)
    if (n == 2) digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); count++; if(count>3) {int count=0;} delay(2); //Not registered (searching)
    if (n == 3) digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); count++; if(count>4) {int count=0;} delay(2); //Denied
    if (n == 4) digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); count++; if(count>5) {int count=0;} delay(2); //Unknown
    if (n == 5) digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); count++; if(count>6) {int count=0;} delay(2); //Registered roaming

        if (n == 1) break;
  }


  Serial.println("Ready to contact!");
  fona.playToolkitTone(1, 100);

  delay(500);

    digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(200);              // wait for a second
    digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
    delay(200);              // wait for a second
    count++;
    if(count>2)//After the third blink
    {
    Serial.print("Calling Phone");
    fona.callPhone(Number); 
    }
}

这是我正在使用的简单电路。

顺便说一句，我正在使用3.7V 1200 mAh电池运行整个系统。

这是一个正常工作的示例代码。它会打开系统并闪烁5次，然后关闭。

int count=0;//This will count how many times we blink before turning off

void setup() {
pinMode(13, OUTPUT);//This is the blinky light
pinMode(6, OUTPUT);//This is the MOSFET gate
digitalWrite(6, HIGH);//Immediately activate the MOSFET gate



}

void loop() {

digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
delay(1000);              // wait for a second
digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
delay(1000);              // wait for a second
count++;
if(count>3)//After the fifth blink
{
digitalWrite(6, LOW);//Shut down the gate cutting off the power.
}
}

我在这里看到几个问题。

1。。从原理图中，我看到您正在将按钮连接到引脚12，但未在代码中使用它。

2。。不需要MOSFET即可将I / O引脚拉高。

3。。面包板电源导轨需要并联连接，因为它们没有在引擎盖下（从字面上看）链接在一起。

请记住要向我们更新您的故障排除进度！
