\brief Initialization routine for Servo.

---

CONFIGURE_CHANNEL_MODE_0:

Initialize Servo. This command causes the pulse width to default to 500uS to 2500uS.

BYTE 0	BYTE 1	BYTE 2	BYTE 3	BYTE 4	BYTE 5	BYTE 6	BYTE 7
0xC0	Pin To Set	0x03 (servo mode)	Pin To Set (Required for compatability with SW19)	Position Value Low Byte	Position Value High Byte	0x00 or 0x01 (Normal or Reverse)	0x55*

*0x55 is recommended, but any byte is acceptable

Response:

Command is echoed back.

Examples:

Set pin 2 to Servo, Position 0x4080, no reverse

0xC0 0x02 0x03 0x02 0x80 0x40 0x00 0x55

---

CONFIGURE_CHANNEL_MODE_1:

Set Pulse widths. This command must come after a servo CONFIGURE_CHANNEL_MODE_0 command for the same pin. Units are microseconds

BYTE 0	BYTE 1	BYTE 2	BYTE 3	BYTE 4	BYTE 5	BYTE 6	BYTE 7
0xC1	Pin To Set	0x03 (servo mode)	Fixed pulse time low byte	Fixed pulse time high byte	Variable pulse time low byte	variable pulse time high byte	0x55*

*0x55 is recommended, but any byte is acceptable

Response:

Command is echoed back.

Examples:

Set pin 2 Servo Pulse width to range between 750 and 1750 uS.
Fixed period is 750 = 0x02EE, variable period is (1750 - 750) = 1000 = 0x03E8

0xC1 0x02 0x03 0xEE 0x02 0xE8 0x03 0x55
