COMMANDS & DATA FOR SWITCH & DISPLAY
? Transferring display data/displaying on LCD: command (1 Byte) + data (256 Bytes)
? Others: command (1 Byte) + data (1 Byte)
? Commands can be accepted only when all bits coincide; otherwise, they are not acknowledged
? Additional commands will not be received until the communication of commands (1 Byte) and data (256 or 1 Byte) is completed
? There is no time limit from the beginning to end of data receipt
? Commands may be executed consecutively (no need to wait between commands)
? Irregular commands or data are not recognized
? Initial status at power activation: LCD display off, LED off (brightness 1/20, color off)
