Subject: Segmentation fault et_wish

Hi All,

I am using et_wish for control system implementation and I wrote a small application to display temperature reading on a label widget. It displays the temperature but does not get updated realtime.

I have copied the tcl tk program below. Please help me to diagnose the problem with the below code.

Many thanks,

Nalaka

Code :
wm geometry . 360x150+200+100
pv linkw temp temp_val1           
pv umon temp change
label .l1 -font {Helvetica 16}  -text " $temp"


#button .btnchange -text change -command {change} -font { -size 15}
grid .l1 -row 0  -column 0
#grid .btnchange -row 1 -column 0



#label .l1 -font {Helvetica 16} -width 10 -textvariable temp

proc change {} {
 global temp
.l1 configure -text "$temp"
}
