- A universal asynchronous receiver/transmitter, abbreviated UART ( /ˈ juː ɑrt/), is a type of "asynchronous receiver/transmitter", a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly used in
RS485-RS422design
- RS-485标准最初由电子工业协会（EIA）于1983年制订并发布，后由TIA-通讯工业协会修订后命名为TIA/EIA-485-A，-The RS-485 standard initially by the Electronic Industries Association ( EIA ) enacted in 1983and released, followed by TIA- Communications Industry Association after revision named
rs485-communication-principle.
- RS-485标准，增加了多点、双向通信能力，即允许多个发送器连接到同一条总线上，同时增加了发送器的驱动能力和冲突保护特性，扩展了总线共模范围，后命名为TIA/EIA-485-A标准。本代码用c语言编写，描述出rs485通讯原理。-RS-485 standard, multi-point, two-way communications capability, which allows multiple transmitters connected to the same bus, while in
