串口、COM口、UART口, TTL、RS-232、RS-485有啥区别

调试时总是会遇到各种各样的接口，各种各样的转换板，似懂非懂的感觉很不爽! 首先，串口、UART口、COM口、USB口是指的物理接口形式(硬件)。而TTL、RS-232、RS-485是指的电平标准(电信号)。 串口：串口是一个泛称，UART，TTL，RS232，RS485都遵循类似的通信时序协议 ...

Discrete-Logic UART Keeps 8-Bit TTL Computer Connected

Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...
