Toykeeper I know what PID is and how it works
But even if I put a pot of water on my hotplate that is 30K above set point it wont start very quick to do a 70% duty cycle its likely starting about 10K above to heat up again,
but your PID even starts to increase current 40 or 50K above set point
I know even before you hit the Temperature ceiling if temp is climbing it is throtteling the output
That Video was made under Lab conditions, the heat up (I know it was way too fast) was in this test totally irrelevant
It was way more interesting what happens when the driver cools down slowly
The fact that the driver is starting to increase current even 30 or 40°C above the temperature set point is causing the heat up bug TA, Matemineco and myself has seen in multiple tets
in the video I could clearly show that it went up to 70% FET duty cycle when the temperature is falling but still 20-25°C above temperature ceiling
.
All what has to be done is keep the PID regulating to Ceiling +5K then disable it for safety reasons till ther light cooled down enough
(current PID model seems not to work so well for flashlights, when its getting hotter than set point, it wents into some sort of oscillation heating up more and more)
instead ramp down current down to MIN_THERM_STEPDOWN and stay at that level till it falls below temp ceiling
This would be sort of “Soft Turbo dropdown” dependant on temperature
Another question is about Lowering the PWM frequency on Moonlight to like 2kHz like you do which code is responsible for that
I would also like that in NarsilM some day
I am currently working on a CC FET driver and I also want to try getting on low levels the PWM to the OPV constantly at this frequency to see if this can be used to dim more
its not working on 15kHz with NarsilM
I have in main.c #define BLINK_AT_RAMP_FLOOR #define MOON_TIMING_HINT
enabled but it does not blink Astrolux wants it
I got round to flash Anduril onto my D4S and I think I bricked it.
I just simply copied the command from the first post without reading more about it and now I wish I did…
That’s what I did. Now after pressing the button only aux LEDs blink in low mode.
After this MCU doesn’t respond to anything
Can I still rescue it somehow or do I have to replace ATTiny on the driver?
Forgive me if that’s something obvious but I’m really not too educated on this stuff…
You live and learn. Eh…
Could you explain how to do it correctly for the future reference?
Will probably use your offer Lexel and place that long overdue order for couple drivers and get MCU straight away.
Actually how would it work with new ATTiny, do they come preprogrammed or how does one place initial firmware on it?
Excuse stupid questions but have no experience with it.
Lexel, can you also slightly modify the code of Anduril/Ramping IOS V2 in such a preflashed MCU? With a appropriate remuneration of course.
In Poland it seems almost no one is capable of doing ui flashing related stuff.
No, not yet. I was trying to find a method which would work for FW3A, but it can’t detect the switch until quite a while after power is connected… and I haven’t added it yet for other lights where it’s easier to do.
So far I only have it on my lightsaber.
Sorry about the bricked MCU. It sucks when that happens… and there’s no easy way to fix it.
Normally, it’s best not to set fuse values at all. Just let them stay as is, and there’s virtually no risk of bricking the MCU. But if you do flash them, I recommend using the bin/flash-*.sh scripts in the firmware repository. They have the correct fuse values; just pick a script which matches your MCU type.
It’s in a few parts of the code — anything which refers to dynamic underclocking. Since it’s a compile-time option, the exact relevant parts of the code are already marked.
Okay, may we see your lightsaber? I wonder if you lean towards the light, or a bit towards the darkness It seems the darksiders have all the cool toys
I’ve not purchased/ made one yet, but I’m waning. Strangely enough, I feel it’s impractical. Doesn’t do anything more than be a cool thing. Of course I’m also the guy with a bunch of flashlights just sitting on a shelf in my office…
So, quick question… In the version used on the FW3A, assume ascending ramping… the first buzz in the pattern is 1 full 7135 and the second buzz is 7 full on 7135’s?
When ramping? Are those called buzzes? I think of them as blips, and the buzzes are when the light flutters during config modes.
As for your question, that’s a config option at compile time, but I’m pretty sure the stock firmware the first blip is a helper indicator to let you know you’re at moonlight mode, so absolute bottom of the ramp, barely using 1 7135, and the second blip, which in the default ramp config is also the top of the ramp, is max 7 7135s. I think.
Could be way wrong, but that’s how I understand it
It does have 8. 1 in a single channel and 7 in the other channel. It is a 1+7+fet driver. If starting at 1 level moon there is a blip fairly quickly, then another and then ramp top.
It may be just a terminology difference, but here’s how I’ve been using the words:
Frame: One timer tick, or about 16ms. There are ~62 frames per second.
Blip: Turning off for less than one frame, as a visual indication that something happened. For example, when passing a reference point on the ramp.
Blink: Turning on (or going to a brighter level) for a short time, to indicate that something happened. For example, when entering or exiting lockout mode.
Buzz / flicker: Switching between two brightness levels quickly (but still slow enough to clearly see). Similar to a strobe, but nowhere near as intense. This is used to indicate that the light is waiting for input from the user.
Strobe: Turning on and off completely at a speed of ~4 Hz to ~100 Hz. This is used to irritate people.
Anduril on the FW3A does up to four blips while ramping up from the lowest to highest level. Hold from off, and these blips may happen:
At ~0.4s, to indicate the button has been held long enough to count as a “hold” instead of a “click”. Let go immediately to stay at the floor level, or keep holding to ramp up.
At ~1.5s, when going from 1x7135 chip to 1+7x7135. Happens at ~130 lm.
At ~2.5s, when going from 8x7135 to 8+FET. Happens at ~900 lm.
At the top end of the ramp, to indicate the ceiling has been reached.
However, depending on where the floor and ceiling are configured, the two middle ones may or may not actually happen. Or they may be at exactly the same level as another blip, in which case only one happens. In the default configuration, the 8x7135 to FET blip is the same level as the ceiling, so only one happens.
It also buzzes or flickers in the ramp config mode, to tell the user when they can click to enter a new value. It goes for 3 seconds, or until the user stops clicking for at least 3 seconds. Each click is confirmed by a blink.
To this: " else if (event == EV_2clicks) { set_state(steady_state, MAX_LEVEL); set_level(MAX_LEVEL); return MISCHIEF_MANAGED;"
This seems to work, but I don't understand why. And I couldn't find any other references to MAX_LEVEL in the main code, though now that I think of it it's probably in FSM somewhere.. hmm.
