Bitwrite函数
Webwrite函数把buf中nbyte写入文件描述符handle所指的文档,成功时返回写的字节数,错误时返回-1. 另一种是: write(const char* str,int n) str是字符指针或字符数组,用来存放一个 … Web3.关键函数void shiftWrite() 这个函数允许你进行移位寄存器输出,HIGH或LOW的方法与使用digitalWrite()完全相同。 ①bitwrite()给data赋是数据和地址 ②shiftout()从高位数据开始传入,并产生脉冲给寄存器位移. 总结. 学习方法要远比一两个知识点的学习重要. 结束

WebTo turn a bit on: data = 1 << bitNumber; The right-hand side ( 1 << bitNumber) is a bit-shift operation to create a suitable bit-mask. It takes the single '1' bit and moves it left until it reaches the desired position. The bitwise-or assignment ( =) combines that new bit-mask with the existing bits in data. This turns the desired bit on, but ... http://reference.arduino.cc/reference/en/language/functions/bits-and-bytes/bitwrite/#:~:text=Writes%20a%20bit%20of%20a%20numeric%20variable.%20Syntax,to%20write%20to%20the%20bit%20%280%20or%201%29.
