we are currently integrating a pressure controller with a custom script using the Switch module.
We would like to use the reach functionality to wait for the corresponding settling bit in the pressure controllers status registers.
For checking the status we use the reach function, which blocks the module until some condition is met.
So when the measurement is stopped during the reach time, the module also blocks until the controller finished adjusting the pressure and the reach function is finally left.
Is there a possibility to catch wether the measurement has been stopped?
Hi Alex,
the simplest solution would be to add a print("Measurement stopped") command in the reach() function of your switch driver. The printed string will be shown in the debug widget, which you access by pressing F2.
I am actually looking for a functionallity to catch wether the user has pressed the stop button in Sweep Me. The issue is that it takes quite some time to readjust the pressure.
So far the measurement blocks for some minutes (with the possibility to forcefully stop the measurement).
Maybe there is a parameter to regulary check in the reach function?
When the stop button is pressed, the drivers function self.is_run_stopped() returns True. You can use this to check during your reach function wether your script should be aborted.
good to hear that the solution worked for you. If you believe your driver might also benefit other users, we would like to include it in our open-source driver library. Please feel free to send it to us, and we will review and enhance it as necessary to fit the SweepMe driver standard.
We have a one-pager containing the License Agreement we use when companies or other contributors share a driver. While it’s not currently available online, you can write an email to contact@sweep-me.net, and we’ll get it to you as soon as possible.
