Help with pico switch with pololu controler

Support Servo controllers and servos
1

hi guys,
i have seriel 8 servo controler and im using it on mini ssc mode.
i want to connect to it with a switch (pico switch).
im tring to make it do on and off.
can someone help me use it in c++, what I need to send to get it on and how can I get it off.
thanks.

I have an old C++ demo program for Pololu mode here. If you wanted to simplify it to use MiniSSC-II mode, it would look something like this:

/*

#include <stdio.h>
#include <windows.h>
#include <time.h>

//FUNCTION PROTOTYPES
HANDLE openPort(int);//Serial protocol stuff, don't worry about it
HANDLE comPort;//Serial protocol stuff, don't worry about it
void putMSSCII(int servo, int angle);//Moves servo (0-7) to angle (500-5500)
void waitMS(int ms);

int done=0;

int main(){
	printf("Pololu Serial Servo Controller Test Program, MiniSSC-II Mode\n\n");
	
	comPort=openPort(5);//***PUT YOUR COM PORT NUMBER HERE!***
	if(done){
		printf("Program Terminated!\n");
		system("PAUSE");
		return -1;
	}

	putMSSCII(0,0);//set servo 0 to position 0
	
	waitMS(500);//pause for 1/2 second

	putMSSCII(0,254);//set servo 0 to position 254	

	CloseHandle(comPort);
	printf("Program Terminated!\n");
	system("PAUSE");
	return 0;
}

void putMSSCII(int servo, int angle){
	unsigned char buff[3];
	DWORD len;

	if(angle>254){
		angle=254;	
	}
	
	if(angle<0){
		angle=0;	
	}

	buff[0]=255;
	buff[1]=servo;
	buff[2]=angle;
	
	WriteFile(comPort, &buff, 3, &len, 0);

	printf("Servo %d Set to %d\n", servo, angle);
}

void waitMS(int ms){
	clock_t endwait;
	endwait=clock()+ms*CLOCKS_PER_SEC/1000;
	while(clock()<endwait);
}

HANDLE openPort(int portnum){
	char port[]="com", pnum[]="Error";
	itoa(portnum,pnum,10);
	strcat(port,pnum);
	
	HANDLE serial=CreateFile(port,GENERIC_READ|GENERIC_WRITE,0,0,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);
	if(serial==INVALID_HANDLE_VALUE){
		if(GetLastError()==ERROR_FILE_NOT_FOUND){
			printf("Error, %s Not Found\n", port);
			done=1;
			return serial;
		}
		printf("Com Error\n");
		done=1;
		return serial;
	}

	DCB dcbSerialParams={0};
	dcbSerialParams.DCBlength=sizeof(dcbSerialParams);

	if(!GetCommState(serial, &dcbSerialParams)){
		printf("Com State Error\n");
		done=1;
		return serial;
	}

	dcbSerialParams.BaudRate=CBR_19200;//CBR_baudrate
	dcbSerialParams.ByteSize=8;
	dcbSerialParams.Parity=NOPARITY;//NOPARITY, ODDPARITY, EVENPARITY
	dcbSerialParams.StopBits=ONESTOPBIT;//ONESTOPBIT, ONE5STOPBITS, TWOSTOPBITS

	if(!SetCommState(serial, &dcbSerialParams)){
		printf("Serial Protocol Error\n");
		done=1;
		return serial;
	}

P.S. I’ve been pushing my luck with less than thoroughly tested code lately, so let me know if this doesn’t work properly.

itws not working
but thanks.
and I need only the way to turn on and off the pico switch.
to use the servo I already know.

Controlling the PicoSwitch should be just like controlling a servo. You would send it to a low “position” (i.e. 0) to switch it one way, and a high “position” (i.e. 254) to switch it the other way.

Thank you very much i but u found another way
