3.14 RS232 Protocol Trigger and Decode (Optional)
RS232 interface is the standard asynchronous transmission interface established by Electronic Industries
Association. Normally, there are two application types: DB-9 and DB-25, suitable for data transmission rate between
0 to 20000b/s, which are widely used in PC communication interface. According to the protocol, the data will be
combined to form a group of specific serial bits, and sent out using asynchronous serial method. The data should be
formed according to the following protocol: a start bit, 5 to 8 data bits, an optional parity bit, and ends with 1 or 2 stop
bits. The data bits size should be decided by the two communication parties, which can be chosen between
5 to 8
data bits, zero parity, odd parity, or even parity can be selected, 1 or 2 stop bits can be chosen. In the following
instruction, a data string transmission is called one frame, shown in the table below:
