功能:返回1字节的数据,但不会从接受缓冲区删除数据,与read()函数不同,read()函数读取该函数后,会从接受缓冲区删除该数据。 write() 功能:输出数据到串口。以字节形式输出到串口,它与print()的区别在于:当使用print()发送一个数据时,arduino发送的并不是数据本身,而是将数据转换为字符,再将字符对应的ASCII码发送...

Parameter Values x: the number from which to read. n: which bit to read, starting at 0 for the least-significant (rightmost) bit.Return Values The value of the bit (0 or 1).Example Code void setup() { Serial.begin(9600); byte x = 0b10000101; // the 0b prefix indicates ...
read by Processing, PD, Max/MSP, or any other program capable of reading data from a serial port. The Processing code below graphs the data received so you can see the value of the analog input changing over time. 可以通过 Arduino串口监视器来查看发送的数据,或者任何可以读取串口数据的软件,例...
