#include <AX12.h >
AX12 (PinName tx, PinName rx, int ID, int baudrate) Create an AX12 servo object connected to the specified serial port, with the specified ID. int SetMode (int mode) Set the mode of the servo. int SetGoal (int degrees, int flags=0) Set goal angle in integer degrees, in positional mode. int SetCRSpeed (float speed) Set the speed of the servo in continuous rotation mode. int SetCWLimit (int degrees) Set the clockwise limit of the servo. int SetCCWLimit (int degrees) Set the counter-clockwise limit of the servo. int SetID (int CurrentID, int NewID) Change the ID of a servo. int isMoving (void) Poll to see if the servo is moving. void trigger (void) Send the broadcast "trigger" command, to activate any outstanding registered commands. float GetPosition () Read the current angle of the servo. float GetTemp (void) Read the temperature of the servo. float GetVolts (void) Read the supply voltage of the servo.
Detailed Description
Servo control class, based on a PwmOut.
Example:
#include "mbed.h"
#include "AX12.h"
int main() {
AX12 myax12 (p9, p10, 1);
while (1) {
myax12.SetGoal(0);
wait (2.0);
myax12.SetGoal(300);
wait (2.0);
}
}

Member Function Documentation
float GetPosition
(
void
)
Read the current angle of the servo.
Returns: float in the range 0.0-300.0 Definition at line 230 of file AX12.cpp .
Read the temperature of the servo.
Returns: float temperature Definition at line 246 of file AX12.cpp .
Read the supply voltage of the servo.
Returns: float voltage Definition at line 258 of file AX12.cpp .
Poll to see if the servo is moving.
Returns: true is the servo is moving Definition at line 166 of file AX12.cpp .
int SetCCWLimit
(
int
degrees )
Set the counter-clockwise limit of the servo.
Parameters:
Definition at line 134 of file AX12.cpp .
int SetCRSpeed
(
float
speed )
Set the speed of the servo in continuous rotation mode.
Parameters:
speed,-1.0 to 1.0 -1.0 = full speed counter clock wise 1.0 = full speed clock wise
Definition at line 87 of file AX12.cpp .
int SetCWLimit
(
int
degrees )
Set the clockwise limit of the servo.
Parameters:
Definition at line 114 of file AX12.cpp .
int SetGoal
(
int
degrees ,
int
flags = 0
)
Set goal angle in integer degrees, in positional mode.
Parameters:
degrees 0-300 flags,defaults to 0 flags[0] = blocking, return when goal position reached flags[1] = register, activate with a broadcast trigger
Definition at line 56 of file AX12.cpp .
int SetID
(
int
CurrentID ,
int
NewID
)
Change the ID of a servo.
Parameters:
If a servo ID is not know, the broadcast address of 0 can be used for CurrentID. In this situation, only one servo should be connected to the bus
Definition at line 153 of file AX12.cpp .
Set the mode of the servo.
Parameters:
mode 0 = Positional, default 1 = Continuous rotation
Definition at line 38 of file AX12.cpp .
Send the broadcast "trigger" command, to activate any outstanding registered commands.
