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);    // go to 0 degrees
       wait (2.0);
       myax12.SetGoal(300);  // go to 300 degrees
       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 240 of file AX12.cpp.

float GetTemp ( void   )

Returns:
float temperature

Definition at line 256 of file AX12.cpp.

float GetVolts ( void   )

Read the supply voltage of the servo.

Returns:
float voltage

Definition at line 269 of file AX12.cpp.

int isMoving ( void   )

Poll to see if the servo is moving.

Returns:
true is the servo is moving

Definition at line 178 of file AX12.cpp.

int SetBaud ( int  baud )

Set baud rate of all attached servos.

Parameters:
mode0x01 = 1,000,000 bps 0x03 = 500,000 bps 0x04 = 400,000 bps 0x07 = 250,000 bps 0x09 = 200,000 bps 0x10 = 115,200 bps 0x22 = 57,600 bps 0x67 = 19,200 bps 0xCF = 9,600 bp

Definition at line 162 of file AX12.cpp.

int SetCCWLimit ( int  degrees )

Set the counter-clockwise limit of the servo.

Parameters:
degrees,0-300

Definition at line 129 of file AX12.cpp.

int SetCRSpeed ( float  speed )

Set the speed of the servo in continuous rotation mode.

Parameters:
speed,-1.0to 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:
degrees,0-300

Definition at line 110 of file AX12.cpp.

int SetGoal ( int  degrees,
int  flags = 0 
)

Set goal angle in integer degrees, in positional mode.

Parameters:
degrees0-300
flags,defaultsto 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:
CurentID1-255
NewID1-255

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 148 of file AX12.cpp.

int SetMode ( int  mode )

Set the mode of the servo.

Parameters:
mode0 = Positional, default 1 = Continuous rotation

Definition at line 38 of file AX12.cpp.

void trigger ( void   )

Send the broadcast "trigger" command, to activate any outstanding registered commands.

Definition at line 186 of file AX12.cpp.
