The Ins and Outs of the TTL Interface
串行通信可在相当长的距离内传输数据,通常与 TTL 标准有关。数据通过串行通信传输,串行通信通过单线传输比特位。数据通过双方--发送方和接收方--以二进制脉冲的形式使用各种串行数字二进制技术进行交换。
RS232 是最早的串行通信协议形式之一,至今仍被串行端口广泛用于连接计算机和设备。它逐位发送数据,非常类似于微控制器的串行信号。这一标准源自 TTL。晶体管-晶体管逻辑(或 TTL)是一种串行通信类型,现代微控制器经常使用这种类型的串行通信,它采用所谓的 UART(或称为通用异步接收器/发送器传输技术)。
Serial communication allows for data transmission over considerable distances and is commonly associated with the TTL standard. Data is transferred through serial communication, which transmits bits at a time over a single wire. Data is exchanged using two parties—the transmitter and receiver—by using various serial digital binary technologies in the form of binary pulses.
