Serial Port Questions
The function for serial interface
RS-232 (ANSI/EIA-232 standard) is compatible with IBM-PC and standard serial connection(serial interface). Can be used for many purposes, such as mouse, printer or Modem, can also take industrial instrumentation. Improvements for the driver and connection, the practical application of RS-232 or the length of the transmission speed is often more than the standard value. RS-232 PC serial port and only point to point communication between devices. RS-232 serial communication maximum distance is 50 feet.
Apart from the interface, there is something similar to that, for the lcd module in face is also a kind of interface connect the MCU and your equipment, it formed to the HMI.
The concept is very simple serial communication, serial by bit (bit) to send and receive bytes. Although the ratio of bytes (byte) of parallel communication slower, but you can use a serial cable to send data while receiving data with another wire. It is very simple and can achieve long-distance communication. Such as IEEE488 parallel passage defined state, the provisions of equipment shall not exceed the line length of 20 meters and length between any two devices should not exceed 2 m; and for the serial port, the length of up to 1200 meters. Typically, serial code for the ASCII character transmission. Complete with three wire communication: (1) ground, (2) send, (3) reception. Because communication is asynchronous serial port can send data in one line while receiving data in yet another line. Other lines used for handshaking, but not required. Serial communication of the most important parameter is the baud rate, data bits, stop bits and parity.
