ARDUINO 编程语法基础ppt课件

ARDUINO编程语法基础,1,结构,setup()loop(),当项目开始运行时会调用setup()函数常我们在其中初始化一些变量、引脚状态及一些调用的库等loop函数是一个循环体，其中的程序将会不断的运行,示例intbuttonPin=3;voidsetup()Serial.begin(9600);pinMode(buttonPin,INPUT);voidloop()if(digitalRead(buttonPin)=HIGH)serialWrite(H);elseserialWrite(L);delay(1000);,2,控制结构,ifif.elseforswitchcasewhiledo.whilebreakcontinuereturngoto,3,语法,;(分号)(大括号)/(胆寒注释)/*/(多汗注释)#define#include,4,算术运算符,=(assignmentoperator)+(addition)-(subtraction)*(multiplication)/(division)%(modulo),5,比较运算符,=(equalto)!=(notequalto)(greaterthan)=(greaterthanorequalto),6,布尔运算符,&(and)|(or)!(not),7,指针运算符,*dereferenceoperator&referenceoperator,8,位运算符,&(bitwiseand)|(bitwiseor)(bitwisexor)(bitwisenot)(bitshiftright),9,复合运算符,+(increment)-(decrement)+=(compoundaddition)-=(compoundsubtraction)*=(compoundmultiplication)/=(compounddivision)&=(compoundbitwiseand)|=(compoundbitwiseor),10,数值,常量HIGH|LOWINPUT|OUTPUT|INPUT_PULLUPtrue|falseintegerconstantsfloatingpointconstants,11,数值,数据类型voidbooleancharunsignedcharbyteintunsignedintwordlongunsignedlongfloatdoublestring-chararrayString-objectarray,12,数值,转换char()byte()int()word()long()float(),13,数值,变量范围与限定符variablescopestaticvolatileconstUtilitiessizeof(),14,函数,数字I/OpinMode()digitalWrite()digitalRead(),15,模拟I/O,analogReference()analogRead()analogWrite()-PWM,16,高级I/O,tone()noTone()shiftOut()shiftIn()pulseIn(),17,时间,millis()micros()delay()delayMicroseconds(),18,数学,min()max()abs()constrain()map()pow()sqrt(),19,三角函数,sin()cos()tan(),20,随机数,randomSeed()random(),21,位与字节,lowByte()highByte()bitRead()bitWrite()bitSet()bitClear()bit(),22,外部中断,attachInterrupt()det
