Example using BL0162 Servo controller for BL0055 Arduino Shield

Samples the Port D8-D13 (portB) switches and moves the servo motors based on the input states.

D8 increments motor 0, D9 decrements motor on channel 0.

D10 increments motor 1, D11 decrements motor on channel 1.

D12 increments motor 3, D13 decrements motor on channel 2.

Connections:

Servo Board Port D0-D2.

Switch Board Port D8 - D13

LCD A0 to A5 (PortC)

The channel to set the position for. First channel is zero.
- VOID	Return

Initialise

	Initialise
Sets up the servo motor interrupts
- VOID	Return

IsAutoMoving

	IsAutoMoving
Is the AutoMoveToPosition movement complete. Returns 1 if the servo is still moving. Returns 0 if the servo movement is complete.
- BYTE	Return

MoveToPosition

	MoveToPosition

- VOID	Return

SetPosition

	SetPosition
Moves directly to the specified position with no interpolation.
- BYTE	Channel
The channel to set the position for. First channel is zero.
- BYTE	Position
Target position to move towards.
- VOID	Return

SetTrim

	SetTrim
Allows the level of trim for each servo channel to be adjusted progmatically.
- BYTE	Channel
The channel to set the position for. First channel is zero.
- BYTE	Trim
0=0us, 1=+25us, 2=+50us, 3=+75us, 4=+100us, 5=-25us, 6=-50us, 7=-75us, 8=-100us
