Assign DMX channel to GPIO about espixelstick

[forkineye]

It should be fairly easy to do. I have another project in the planning stages that will require software PWM, just no time to work on it yet.

Great! Thanks. Looking forward to test it.

I have some hardware arriving soon which could really use this feature.

Did you get anywhere ? If not I'll probably do it in the next couple of weeks.

I'll add a gpio/PWM tab to the GUI with 3 columns:
Gpio, enabled, dmx channel
12 [x] 1
4 [x] 2

@penfold42 I hadn't done anything with this yet. If you decide to work on it, I'd like to keep it as a different compile time "Mode", like Pixel and Serial as the hardware most people use this on (ESPixelStick) wouldn't allow for mixed capability due to lack of available pins (ESP-01).

Will do - I just got the basics working 5 mins ago.

Ideally I'd like to keep it as separated as possible but the globals being in the same .h with all the structure makes it trickier - a subtle hint to peek at my other PR !

It's basically done - the GUI layout looks crap at the moment but it works.

I've only tested gpio4 with a mosfet driving a 5w 12v dimmable led halogen replacement bulb.

I've fixed the layout and confirmed support for most of the gpios.

I just need to hide the HTML config if support isn't compiled in.

Do you mind if I change device mode to be a bitfield? Pwm can coexist with both serial and pixel modes and this is a quick way to support it.
Bit 0 pixel, bit 1 serial, bit 2 pwm
Would yield:
0 invalid
1 pixel
2 serial
3 invalid
4 invalid
5 pixel + pwm
6 serial + pwm

All done! (I hope)
#66

And now removed from this repo as of today.

I’ll be maintaining this support in my repo along with other features:
