我們在編譯ATTINY85和ATTINY84的時候，特别是用arduino IDE的時候，一定要特别注意，他這個引腳都不是一一對應的。下面我們來看一下他是如何對應的呢？
這是attiny84對應arduino引腳的表格。
是以我們在對引腳進行程式設計控制的時候要看清楚對應的引腳。
下面是attiny85的表格：
好，現在我們來試一下序列槽：
#include "SoftwareSerial.h"
const int Rx = 3;
const int Tx = 4;
SoftwareSerial mySerial(Rx, Tx);
void setup()
{ pinMode(Rx, INPUT);
pinMode(Tx, OUTPUT);
mySerial.begin(9600);
void loop()
{ mySerial.println(val); }
注意，由于這個單片機沒有序列槽，是以我們隻能使用軟序列槽實作序列槽的功能，但是注意，波特率不要設的太高，9600就可以了。設定的太高，軟序列槽可能會讀寫出錯。
下面是85的軟序列槽測試程式：
#include "SoftwareSerial.h"
const int LED = 1; // this is physical pin 6 for the LED
const int ANTENNA = 2; // this is physical pin 7, connect wire as antenna
const int Rx = 3; // this is physical pin 2
const int Tx = 4; // this is physical pin 3
SoftwareSerial mySerial(Rx, Tx);
int val = 0; // variable to store antenna readings
void setup()
{
pinMode(LED, OUTPUT); // tell Arduino LED is an output
pinMode(Rx, INPUT);
pinMode(Tx, OUTPUT);
mySerial.begin(9600); // send serial data at 9600 bits/sec
}
void loop()
{
digitalWrite(LED, HIGH); // turn LED ON
delay(500);
digitalWrite(LED, LOW); // turn off
delay(500);
val = analogRead(ANTENNA); // read the ANTENNA
mySerial.println(val); // send the value to Serial Monitor, ^Cmd-M
digitalWrite(LED, HIGH); // turn LED ON
delay(10); digitalWrite(LED, LOW); // turn off
delay(500);
}
下面是attiny84的序列槽程式，來對比一下：
#include "SoftwareSerial.h"
const int LED = 5; // this is physical pin 8 for the LED
const int ANTENNA = 1; // this is physical pin 12, connect wire as antenna
const int Rx = 7; // this is physical pin 6
const int Tx = 6; // this is physical pin 7
SoftwareSerial mySerial(Rx, Tx);
int val = 0; // variable to store antenna readings
void setup()
{
pinMode(LED, OUTPUT); // tell Arduino LED is an output
pinMode(Rx, INPUT);
pinMode(Tx, OUTPUT);
mySerial.begin(9600); // send serial data at 9600 bits/sec
}
void loop()
{
digitalWrite(LED, HIGH); // turn LED ON
delay(500);
digitalWrite(LED, LOW); // turn off
delay(500);
val = analogRead(ANTENNA); // read the ANTENNA
mySerial.println(val); // send the value to Serial Monitor, ^Cmd-M
digitalWrite(LED, HIGH); // turn LED ON
delay(10);
digitalWrite(LED, LOW); // turn off
delay(500);
}
