may the ESP not supply enough to kill it, good for you, but better add a resistor.

@Links2004: Without it works well, however I'll consider adding one in the final design.
@Links2004: What amazes me is why the led strip powers on after some threshold instead of dimming smoothly.
Markus
@Links2004
you go over the ratings of the MOS, may this is a side affect of this.
or do you try to dimm with the CNY?
Helio Machado
@0x2b3bfa0
@Links2004: I'm PWMing the CNY LED.
Markus
@Links2004
yes what do you have at pin 4 and 5 of the CNY
Helio Machado
@0x2b3bfa0
@Links2004: Drain and Gate of the mos.
Markus
@Links2004
do you have a pulldown on Gate?
Helio Machado
@0x2b3bfa0
@Links2004: I mistaken. I have 5V and Gate and not Drain and Gate. However, I have a pulldown between Gate and Source (470kΩ)
Markus
@Links2004
you can try somethink like this to see if its the CNY or the MOS how makes the problem

or try to use 10V instead of 5V, 10V is recommended in the datasheet.
Helio Machado
@0x2b3bfa0
@Links2004: Ok, I'll try later. Dinner time ;-)
Thank you for your help!
Bye!

I see those talks about CNY17-2, but this opto-coupler still has a BVceo of 70V ... I mentioned SFH60 and H11D1, but there is also SFH619 with darlington output.
Martin Ayotte
@martinayotte
BTW, since you only need a Vgs about 10V for making the MOSFET satured, you can add zener diode to avoid using a high BVceo optocoupler

@celsworth
more ESP32s apparently turning up, where is mine :(
Martin Ayotte
@martinayotte
I'm waiting for my ESP32 too ... :worried:

@toxuin
Where are one supposed to get one?.. I'd be glad to check it out.
Chris Elsworth
@celsworth
beta programme is closed now, can't get one unless they reopen it (or wait for general availability)
Tony
@toxuin
:(
Sven Eliasson
@comino
Didnt get ESP32 since now, too. Some people already got one?
Chris Elsworth
@celsworth
at least two people reported getting theirs, kolban and amica
Sven Eliasson
@comino
both living usa?
Chris Elsworth
@celsworth
no clue :)
Sven Eliasson
@comino
transport china<>usa is quicker than to europe
Perfere to get it on 24th as christmas present anyway :P
Chris Elsworth
@celsworth
heh I don't think my family would approve if it arrives on the 24th and I ignore them for a week ;)

@iggr, @Links2004 for you specifically ))

@Links2004
will test it later.
Dmitry Kireev
@kireevco
good.
thank you!!

@kireevco
does anyone know which gdb source works with esp8266?
Markus
@Links2004
there is an openocd fork for the ESP but i never test it.

@kireevco
@Links2004 any known binutils that produces xtensa-lx106-elf-gdb?
(that works)
Markus
@Links2004
never seen one.
Dmitry Kireev
@kireevco
esp-open-sdk has one
it has xtensa-lx106-elf-gdb

Is there an example out there for downloading a png file, storing the value in SPIFFS then displaying it via the webserver?
Markus
@Links2004
not as one, example.
Steve Nelson
@zenmanenergy
how about just downloading and storing a png into spiffs? i didnt see that in the list of examples.
