入门萌新救助一段代码解释
数码管实验学习,以下这段代码是教程中的,求助一些问题,底子比较薄若,希望有前辈指点迷津。:'(:'(byte seven_seg_digits = { (这一段是什么意思呢?看不懂结构,能帮忙明细一下吗?):dizzy:
{ 1,0,0,0,0,1,0,0 },
{ 1,0,0,1,1,1,1,1 },
{ 1,1,0,0,1,0,0,0 },
{ 1,0,0,0,1,0,1,0 },
{ 1,0,0,1,0,0,1,1 },
{ 1,0,1,0,0,0,1,0 },
{ 1,0,1,0,0,0,0,0 },
{ 1,0,0,0,1,1,1,1 },
{ 1,0,0,0,0,0,0,0 },
{ 1,0,0,0,0,0,1,0 }
};
void setup() {
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
}
void sevenSegWrite(byte digit) { (这一段是彻底看不懂了,教程解释的太笼统了,无法消化,求高人明细):dizzy:
byte pin = 4;
for (byte segCount = 0; segCount < 8; ++segCount) {
digitalWrite(pin, seven_seg_digits);
++pin;
}
}
void loop() {
for (byte count = 10; count > 0; --count) {
delay(1000);
sevenSegWrite(count - 1); (这到底是什么意思呢?):'(
}
delay(2000);
}
求好心高人指点一下,晚辈拜谢了。。。
byte seven_seg_digits = { (这一段是定义了一段显示数字时候用到的数据,每一个大括号里面的一串表示一个数字
{ 1,0,0,0,0,1,0,0 },
{ 1,0,0,1,1,1,1,1 },
{ 1,1,0,0,1,0,0,0 },
{ 1,0,0,0,1,0,1,0 },
{ 1,0,0,1,0,0,1,1 },
{ 1,0,1,0,0,0,1,0 },
{ 1,0,1,0,0,0,0,0 },
{ 1,0,0,0,1,1,1,1 },
{ 1,0,0,0,0,0,0,0 },
{ 1,0,0,0,0,0,1,0 }
};
void setup() {
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
}
void sevenSegWrite(byte digit) { (这一段就是把上面那个定义的数据里面的一个大括号的数据 显示出来
byte pin = 4;
for (byte segCount = 0; segCount < 8; ++segCount) {
digitalWrite(pin, seven_seg_digits);
++pin;
}
}
void loop() {
for (byte count = 10; count > 0; --count) {
delay(1000);
sevenSegWrite(count - 1); (一个循环,把上面的数据一个大括号一个大括号的分开来显示)
}
delay(2000);
} 建议多看看C语言的入门资料
或者多看一些Arduino的相关
