changing Hal parameters

Hi,

I use a bash script for gear change and was kind of lazy. I have 12 manual selectable gears and a two clutches (1.1 and 1:1.6 gear reduction) I can use. So it is more or less a two stage gearbox. I use one gear change module for the clutches and set the parameters with a bash script / MCode. In Hal everything looks fine the parameters are changed. BUT when I tested it with the machine running it looks like the initial parameters are used.
 For example on startup the min_speed_2 parameter is set to 1600 I change gear and the in Halshow min_speed_2 parameter is now 72 as it should be for this gear when I try to run the spindle now at 80 rpm the output is still 1600

is there a way to get the parameters updated or a neat way to work with a two stage gearbox?

thanks Patrick

Can you post your script / MCode?

yea sure  this is the script where I change the parameters. In Halshow I see that they are updated but the module still works with the initial parameters.

I took the long route and set up all 24 gears in gear change and changed my M codes.

It's a long shot but sometimes a forced synch helps:

Hi,

If your module isn't updating, maybe create a thread.

    halcmd loadrt threads name1=gear-thread
    halcmd loadrt yourgearmodule
    halcmd addf update gear-thread

Then in your component add function declaration:
static void update();

Add function eof:
static void update()
{
    // here your code to update or initialize the values.
}

If you don't know how to. Then you can post your component source file.
