What would happen if I flash STAR off-time but didn’t have a capacitor in place? I’m looking for “off-time” memory during mode selection, but “no memory” once the light is powered off. Wondering if I can accomplish this without the cap.

Usually, the result ends up being that every click is registered basically as a "short click", where the driver would advance to the next mode (not what you want).
Doesn't selecting "no memory" accomplish what you want, anyways? The off-time STAR with capacitor in place functions like you are describing.
But that IS what I want. When the light is on I always want a short click to advance modes. When the light is off & turned on I want it to always turn on in the first mode.
I found that regular “STAR” (on-time) even when set to “no memory” would require two clicks to advance modes because “memory” had set it. That was annoying.
Anyway, I just tried flashing STAR off-time to a 105D without capacitor and it IS working just as I wanted! Single-click always advances mode & always starts in first mode! (EDIT-see next post.)
My problem now is that I need reverse mode order which I originally planned to get by soldering star #3 on a 105C. Can I change mode order in the code simply by reversing the line entries to put high first? (I’m referring to the lines where I enter my desired PWM values – the only lines I ever edit.) Or are there other lines in the code to edit also?

WAIT! My bad! You’re right RMM! Upon closer inspection it’s acting like a driver with “next mode memory” which is not what I want! Doh! So I guess I’m back to switching the 105D out for a 105C.
I would still like to hear an answer to switching mode order in the code though.

You can use ToyKeeper's "NOINIT" modification to the code that will give you off-time without the capacitor, so you can use it on the 105D without adding any extra parts (for best timing, also change the fuses to those listed in the initial code description). (it's in ToyKeeper's repository).
To switch the default mode order in the code, find this:
if((PINB&(1<<STAR3_PIN))==0){// High to Lowmode_dir=-1;}else{mode_dir=1;}}
Then change to this (or just solder Pin 3 to ground with the default code...):
if((PINB&(1<<STAR3_PIN))==0){// High to Lowmode_dir=1;}else{mode_dir= -1;}}

Thanks RMM! Perfect solution for me! Others previously pointed me toward “Bistro” with brown out detection and I didn’t realize ToyKeeper had a version of STAR modified with brown out detection as well.

Would there be a way to configure the LVT in STAR so that it would require a duration of low voltage before going into ADC_Low or ADC_Crit?
I’ve made a couple of lights that are temperamental with the LVT. A casual knock, or bump will trigger the LVT.
Any help here?
Doesn’t it already do that? In STAR it has a “lowbatt_cnt” thing so that it won’t step down unless the value is low several times in a row. You could slow it down just by increasing the number of readings required to trigger it.
I’m assuming this is the line of code I would change:
“if (++lowbatt_cnt > 8)”
A setting of 8 (default) would be 4 seconds and in this case definitely shouldn’t be tripping it. A brief bump is really only a fraction of a second.
I’ll try increasing the value to 8, 16, etc and see if that has any effect. Is there a max length of time that this program will accept ( say one or two minutes)?
If a quick bump trips it, maybe it’s not LVP causing the problems. Maybe it’s actually losing power and rebooting? Loose springs barely making contact? Firmware won’t be able to fix that.
That was my thought as well but one thing stands out. I have removed ADC_Low and only use ADC_Crit in my program. When it senses LVT it flashes 10 times then turns off.
The 10 flashes then turnoff is exactly what it is doing when bumped.
No, doesn’t sound like a reboot. Could easily be a poor connection though. I’ve had false LVP warnings when something wasn’t connected well, and it was bump-sensitive.

Toy – as always, you’re a big help. Many thanks.

I would assume it’s probably fine up to 254.

Thanks for the help. I’m going to tinker with “if (++lowbatt_cnt > 8)” and just see if that makes for a quick fix.
