Defines
#define	SERVO_MAX_ANGLE   180
	The maximum angle of the servo.
#define	SERVO_MIN_WIDTH   204
	The 1ms pulse width for zero degrees (0 - 4095).
#define	SERVO_MAX_WIDTH   410
	The 2ms pulse width for 180 degrees (0 - 4095).
#define	SERVO_TIMER1_TOP   20000
	The top value for XLAT and BLANK pulses.
#define	SERVO_TIMER2_TOP   77
	The top value for GSCLK pulses.
Functions
void	tlc_initServos (uint8_t initAngle)
	Initializes the tlc.
void	tlc_setServo (TLC_CHANNEL_TYPE channel, uint8_t angle)
	Sets a servo on channel to angle.
uint8_t	tlc_getServo (TLC_CHANNEL_TYPE channel)
	Gets the current angle that channel is set to.
uint16_t	tlc_angleToVal (uint8_t angle)
	Converts and angle (0 - SERVO_MAX_ANGLE) to the inverted tlc channel value (4095 - 0).
uint8_t	tlc_valToAngle (uint16_t value)
	Converts an inverted tlc channel value (4095 - 0) into an angle (0 - SERVO_MAX_ANGLE).

Define Documentation

#define SERVO_MAX_ANGLE   180

The maximum angle of the servo.

#define SERVO_MAX_WIDTH   410

The 2ms pulse width for 180 degrees (0 - 4095).

#define SERVO_MIN_WIDTH   204

The 1ms pulse width for zero degrees (0 - 4095).

#define SERVO_TIMER1_TOP   20000

The top value for XLAT and BLANK pulses.

This is with the div8 prescale, so The default is 20000, which corresponds to 50Hz.

#define SERVO_TIMER2_TOP   77

The top value for GSCLK pulses.

Related to SERVO_TIMER1_TOP by The default is 77.
