Subject: M code and C programs

Hello,

I am trying to execute a C programm with a M gcode. Is there a way to test in the C programm which M code has been used?

For example:

I execute a C program with M100. Can i find out in the C program that M100 has been used?

Thanks. And keep up the good work.

If no P Q R parameters are specified the MCode number is placed as an integer into the KFLOP persist variable specified by the Var setting before the C program is executed.

Regards

Thank. I have now been able to create just 1 C program for M3, M4 and M5. It runs in thread 2 and takes Var 1. In the C program I do a switch statement something like this:

Switch persist.Userdata[1]

{

case 3

Jog CW

Laststate=1

break

case 4

Jog CWW

Laststate=-1

break

case 5

Stop spindle

Laststate

break

}

it works great.

I would like also to add a case block for the S, but the gcode S only transfers the desired speed to variable 113.

Is there a way to tell in a C programm that the S had been used? Is it possible to modify some .h file, to let the S also put a certain int in a given var?

I try to create just 1 C file for all the above.

Thanks.
