【convoy】H4 and B35AM options are updated

@Simon Mao

Although the same function has been achieved, driver manufacturer does not use the existing open source code because of the different circuit principle. This circuit currently uses code written by the driver manufacturer itself.

I earlier asked if it’s the same “Biscotti” driver (as used in the Convoy C8+ with Biscotti firmware).

Based on this explanation, the SST40 “Biscotti” is not the same “Biscotti” but “something similar function”.

I’m curious then, would it also have the same 12- mode groups, enable/disable mode memory? Or maybe just “something similar” in concept?

Would be good if someone has already gotten the “SST40-Biscotti” driver and put it to the test.

(As of the moment, our country is in lockdown, so most overseas sellers have stopped shipping to our country for a full month now and may still not be able to do so in another 2 weeks…) [eg. Banggood says “No shipping method available” for ALL products now, whereas before, only “pure battery products” have “No shipping method available”]

So it’s a Biscotti clone, but not Biscotti. And given that information is being withheld, I can’t modify it and flash my own version like I’ve been able to with Biscotti (custom modes etc).

Thanks, no thanks.

(I’d strongly suggest using another name - even “Biscuit (Biscotti-clone)” or similar. Because it’s not the same firmware.)

I agree. Knowing whether we can use our own customized variants is a big deal and re-using the name may mislead people to think that it’s possible.

i have no difficulty with delivery to Philippines.
Even mailing a mask is no problem.
the function is the same instead of “similar”

This was my mistake. At first, I thought that the driver manufacturer used the biscotti code. Later, I realized that it was the code he wrote himself.
I havent given a name to this, so simply call it 12 groups sst40 driver

[oweban]

No probs Simon - we can all get blindsided.

Smells like surströmming, sorry to say.

So who is going to dump the MCU's code?

[Rayoui]

I did notice a difference with mine but wasn’t sure if it was just a quirk with my build (used it in a photo red triple). When set to the five mode group, there seems to be a large jump between modes 2 & 3. My other Biscotti drivers have very linear mode spacing. Not really a complaint, just an observation.

[JaredM]

I have a quirk in a 20mm “SST40” driver that I recently bought from your AE store. Between modes 1 and 2 there is a bright “pre-flash”. Is this normal? Anybody else experiencing this? It’s installed in an S21a running a triple XPL_HD from an LG M50.

[zak.wilson (Zak)]

Simon, what’s the order code (or at least CRI bin, the 16th digit which can be B, H, or U) for the XHP35 HI 4000K B4-40E?

I asked this to Simon nearly two weeks ago via message in AliExpress. I told him that, according to datasheet, a B4-40E should be U CRI code or CRI90+, whereas the D2-1A (6500K) should be H CRI code or CRI80+. Simon replied “uh, sorry, the LED I sell is not high CRI LED”. Confusing, I know.

This may be caused by a high internal resistance somewhere, or it may be a driver problem.

So, to amend the mistake, the post title should be changed… or not?

[abgx1]

Tldr;

So, is it possible to buy s21a with biscotti?

Simon - no harm intended. No worries. We are all glad you are involved so much with us and listen. We just like to get the specifics.

That's all true - your listings never said Biscotti.

Again, you with the Convoy brand have been a long time major part of BLF - "quality at budget prices", could be your motto and BLF's.

I second that.
Myself I’m not a fan of Convoy lights because they tend to be too bulky for my preferences - but nevertheless there is no brand I respect more than Convoy.

[hodor]

Are the groups the same as biscotti? Noticeable PWM?

[Barkuti]

hodor, SST-40 drivers are regulated linears. Current is regulated by tuning the MOSFETs' V_GS with the onboard sense resistor voltage drop feedback. PWM is thus senseless.

[hodor]

Oh right, wasn’t thinking, thanks.
