Serial Command Protocol for MTKxx
1. A serial protocol for driving MTK µchip through external +3.3VDC serial device (USB or
COMx) is available. It may facilitate manufacturing process. Thus, both P201 connector from
chassis board or either VGA input can also be used using pin12 (RXD) & pin15 (TXD) just
taking care that "FactoryKey" from Factory Menu is enabled.
2. The required serial port settings are as below
•
115200 bps
•
8 data bit
•
1 bit stop
•
none parity
3. The command format is like hereafter described into BNS representation:
•
0xBB + Command + Data[[..] + ..] + 0xEE
Both 0xBB and 0xEE bytes are mandatory and used as header and footer of the transmitted
frame. Apart from INIT frame that is described further, all sent bytes need to be triggered before by
an additional one as 0x50. So a complete frame might match following one:
•
0x50+0xBB+0x50+Command+0x50+Data[[..]+0x50+..]+0x50+0xEE
4. At first time, it might be required to initialize MTK µchip by using once below INIT command
(without any triggering byte):
•
0x02 + 0x00 + 0x00 + 0x13 + 0x01 + 0x00
5. A none exhaustive list of commands is already available.
