8、Serial Control Protocol
BY8301 built-in standard asynchronous serial UART interface, are 3.3V TTL level interface. Can be converted to RS232
level through the MAX3232 chip. Communication data format is: Start bit: 1; data bits: 8; Parity: None; Stop Bits: 1.
Using the computer serial debugging assistant, you need to set the correct serial port parameters, settings shown:
Protocol command format:
Start code
length opcodes parameters
check code
end code
0X7E see below see below
see below see below 0XEF
Note: all the data as a hexadecimal number."Length" refers to the length of the + operator code +
Parameter Length + checksum,"Checksum" refers to the value of the length of the operation code, parameters
negated, customers can get through checksum calculator.
For example, playing instructions for 7E 03 01 02 EF
Length 03 is thus obtained: is "03", "01", "02" 3-digit length;
checksum 02 is obtained by:
First, open the calculator programmer mode selection;
Then select the hex, double word;
Finally, click to calculate 3 Xor 1 = 2
Command sent successfully returned OK, stop the song finishes playing return STOP.
