Retrieving parameters values

Hi,

I'm trying to retrieve several numbered parameters, but with a minimum of hal widgets. I know I should have tried to build a custom widget, but I never did it and thought it would be easier this way. I changed my point of view (using one hal widget per parameter), but I would like to know how this should have been written :

In postgui.hal I have :
The code is running, but don't do what I want. It seems lcdnumber.value() is not updated fast enough to have paramEdit_MD_D updated with the right text, both paramEdit_MG_D and paramEdit_MD_D are receiving the same text. The " while not STATUS.is_interp_idle():" does nothing.

Thanks

I'm assuming this is just test code, as you could just set the paramEdit directly (based on the code you showed)

Typically I would use a callback (changed signal) from the lcdnumber or better yet a plain HAL pin to update paramEdit_MG_D.

while not STATUS.is_interp_idle(): might be better to try :
STATUS.cmd.wait_complete()

As an alternative you could use the HAL module to read the pins directly:
value = hal.get_value("motion.analog-out-05")

What do you mean by "you could just set the paramEdit directly " ?

STATUS.cmd.wait_complete() doesn't solve my problem.

I tried (in a button_click callback) :

ACTION.CALL_MDI("M68 E4 Q#1217")
while not STATUS.cmd.wait_complete():
time.sleep(0.1)
self.w.doubleSpinBox_DJG.setValue(self.w.lcdnumberDJ.value())

and I have to click twice to see lcdnumberDJ updated

So I try

ACTION.CALL_MDI("M68 E4 Q#1217")
time.sleep(2)
self.w.doubleSpinBox_DJG.setValue(self.w.lcdnumberDJ.value())

I watch motion.analog-out-04 in halshow at the same time, I see it changing immediatly when I click and then lcdnumberDJ appearing 2s later but without being updated. I click a second time and it works.
Do you know why ? I surely need to call some process_message like function between .. ?
