It seems like strcmp works when it is placed in an if statement but not as shown below inside the when()

 

when (strcmp(voltage, "STANDBY")==0) {

            /* turn light on */

            light = 8;

            pvPut(light);

    } state light_on

}

Including string.h in the top of your .st file should allow you to use `strcmp`:

%%#include “string.h”

Hello,

 

I am working on the sequencer record and wondering where to place conditionals, I was trying to do a string compare inside the when() but it did not want to compile.

 

I see some examples in the documentation where they place a conditional in the when() block

 

when (voltage > 2) {

 

            /* turn light on */

            light = ON;

            pvPut(light);                           

   

    } state light_on

}

 

But I have also seen where they have if statements inside of a when() with no check

 

when () {

        if(strcmp(voltage, "STANDBY")==0){

 

            /* turn light on */

            light = 8;

            pvPut(light);

   

    } state light_on

}

 

I was hoping to do something like this

 

when(strcmp(voltage, "STANDBY")==0){

 

}

 

Thanks,

Adam
