is it possible to set the t0h and t1h

[MrGokilz]

Hello Makuna,

I like your Lib very much. Thanks for your good works.
I am using your lib with ESP32 S3. Is it also possible to change the t0h, t0l, t1h and t1l?

Thanks in advance.

Regards,
Gokilz

The method defines the timing. The method is specific to the LED chip. What chip are you using?

[Makuna]

Its more than just timing of the pulse, there is also the total pulse size or often referred to as the data speed in kbps.
Further, the reset time is needed.

The WS2811 is close to that. I would suggest it.
The Gs1903 is dead on, but has a reset time of 40us, which maybe faster than your chips support.

The spec I see states 200us reset needed. Further, it does state 1.25 total pusle, so I would avoid the GS1903 as its below that by a bit.

You can create an issue to add specific feature for Wlicled, it will be just an alias of the WS2811.

can I maybe "only" change this variable in the correct methode
const static DRAM_ATTR uint32_t RmtBit0 = Item32Val(300, 900);
const static DRAM_ATTR uint32_t RmtBit1 = Item32Val(900, 300);
const static DRAM_ATTR uint16_t RmtDurationReset = FromNs(50000); // 50us

I just changed the value and then it works. Thanks for your help

If you are maintaining your own custom version, then you can change it how ever you want ;-)

If you want the support to trickle through NeoPixelBus so you don't have to maintain it, then you will need to do more.

NeoPixelBus gets refactored all the time, so maintaining an external version can get time consuming. I bring this up as a big refactor is in the works right now.

[MrGokilz]

yeah, that's the problem, if I change it by my self.

If it is possible, maybe you can define a "special" method, where the user can set the timing by him self 🙏🏻

You can create an issue with this request. But note that few Methods can support this. On ESP32, RMT and BitBang can while the I2S cannot. A few other platforms have BitBang support that can try but don't often have the resolution to achieve anything more than using the defaults.

Dynamic reconfig is not a big goal of this library (check the Wiki for why).

I would rather spend the time exposing them by name.
