serial commands to ssc-32

Hi,

Basically I am using an lpc1786 to send a commend to a servo controller board, scc-32, in order to move a servo. The code I have tried is as follows:

ssc

#include "mbed.h"

 
Serial ssc(p9, p10);  // tx, rx
 
int main() {
    ssc.baud(9600);
    ssc.printf("#4P1500\n");
    ssc.printf("#4P1000T500\n");
}

I have tried variants of it but no luck. I have the tx s connected to rx s and ground to ground. Also set the baud rate to 9600 on the board and both boards and the servo is powered. The green light on the ssc-32 blinks every time I send, which means it received a valid byte.

In the user guide it also says: All SSC-32 commands must end with a carriage return character (ASCII 13). In Arduino this can be done using the serial.println(); command.

I am not sure if the printf command is the one I should be using but I guess so. Hence as far as I can see I am doing everything as I am supposed to and am at a loss. Any help appreciated!

Thanks Lanfear

You may want to try the 'return' \r instead:

ssc.printf("#4P1500\r");

That did it, thanks.
