Help with C_Counter reset

[sean.e]

I'm using a C_Counter to select an input on an ISwitch.  The counter is driven by a trigger and the counter has another trigger for count reset.  That much works fine. 

I'm also trying to automatically reset the counter if the trigger is pressed when the counter is at maxcount.  My problem with this bit is that I have to press the increment trigger twice for the automatic reset to occur.  Any ideas on how to avoid having to trigger multiple times for auto-reset?

Here's what I've coded up:

HEADM adc 2 2 iSwitchL-out iSwitchL-out Empty Empty 1 menupage-obj ;=0,0,100,0
ISWITCH iSwitchL 4 SelectCounter-out adc-in1 adc-null adc-in1 adc-null ;=600,0,100,0
C_MERGE resetCounter 2 SelectCounter-timeout reset-out ;=425,150,100,0
STEXTKNOB SelectTextKnob %s select 4 0 SelectCounter-out "textknob: select 0" "textknob: select 1" "textknob: select 2" "textknob: select 3" ;=600,200,100,0
C_MERGE incrementCounter 3 SelectTextKnob-textnum_out increment-out resetCounter-out ;=425,300,100,0
C_COUNTER SelectCounter incrementCounter-out resetCounter-out 1 3 ;=600,325,100,0
MENUPAGE menupage menupage menupage 5 increment-obj SelectTextKnob-obj counterMonitor-obj spacer-obj reset-obj ;=975,125,100,0
MONITOR counterMonitor SelectCounter-out "counter:         %1.0f" cntMonitor ;=825,325,100,0
TRIGGER increment increment increment ;=125,550,100,0
TRIGGER reset reset reset ;=275,550,100,0
TEXTLINE spacer "" ;=1100,200,100,0

Repro by pressing the increment trigger until counter displays 3.  What
I'm hoping for, is that the next press of the increment trigger will
cause reset.  But instead, it takes two presses of the increment
trigger to reset the counter.

By re-ordering the inputs to the C_Merge that is used to drive the
counter clock input, I'm able to get the auto-reset to work without
requiring multiple triggers at maxcount.  But it is done at the expense
of the manual reset trigger.  The manual reset trigger works fine for
all values except at maxcount – at which point it requires two
consecutive trigger presses.  Fine trade off compared to the previous
behavior.

Here's the current version of the test:

HEADM adc 2 2 iSwitchL-out iSwitchL-out Empty Empty 1 menupage-obj ;=0,25,100,0
ISWITCH iSwitchL 4 SelectCounter-out adc-in1 adc-null adc-in1 adc-null ;=575,25,100,0
C_MERGE resetCounter 2 SelectCounter-timeout reset-out ;=400,175,100,0
STEXTKNOB
SelectTextKnob %s select 4 0 SelectCounter-out "textknob: select 0"
"textknob: select 1" "textknob: select 2" "textknob: select 3"
;=575,225,100,0
C_MERGE incrementCounter 3 resetCounter-out SelectTextKnob-textnum_out increment-out ;=400,325,100,0
C_COUNTER SelectCounter incrementCounter-out resetCounter-out 1 3 ;=575,350,100,0
MENUPAGE
menupage menupage menupage 5 increment-obj SelectTextKnob-obj
counterMonitor-obj textKnobMonitor-obj reset-obj ;=950,150,100,0
MONITOR counterMonitor SelectCounter-out "counter:         %1.0f" cntMonitor ;=800,350,100,0
MONITOR textKnobMonitor SelectTextKnob-textnum_out textknobMon:%2.4f knobMonitor ;=800,225,100,0
TRIGGER increment increment increment ;=100,575,100,0
TRIGGER reset reset reset ;=250,575,100,0

Now
I'm trying to figure out why incrementing the STEXTKNOB only causes the
C_Counter to increment once.  If you increment the textknob multiple
times (using the up arrow key), its monitor (added in the current
version of the test) shows the expected output of the knob, but the
counter monitor only updates once – the counter and textknob monitors
get out of sync.  Not so when using the Trigger instead of the
STextKnob.

Here is a version that works, but I really just tricked your own patch. What's happening in your most recent version is that when you are at "3" and hit the "increment" trigger, you first increment the counter, get the flag for "max value reached" then reset. The only thing I added is a connection from the reset trigger to the C_MERGE with the increment trigger in input (I added a 4th input). Seems to work. There must be more elegant versions – I hope someone will share!

Nice. I'm traveling this week so can't try it out yet.  Thanks.

Thanks – that clears up the reset.  Will continue working on the text problem and post as a separate thread.

I decided to punt on the STextKnob and use a TextTrigger instead (hence the other couple of posts regarding TextTriggers).  This is what I've ended up with:

HEADM adc 2 2 iSwitchL-out iSwitchL-out Empty Empty 1 menupage-obj ;=0,25,100,0
ISWITCH iSwitchL 4 SelectCounter-out adc-in1 adc-null adc-in1 adc-null ;=575,25,100,0
C_MERGE resetCounter 2 SelectCounter-timeout reset-out ;=425,325,100,0
TEXTTRIGGER texttrigger 4 SelectCounter-out "sel 0" "sel 1" "sel 2" "sel 3" ;=575,300,100,0
C_MERGE incrementCounter 3 resetCounter-out texttrigger-out reset-out ;=425,175,100,0
C_COUNTER SelectCounter incrementCounter-out resetCounter-out 1 3 ;=575,175,100,0
