APA102 change DataPin

Issues
1

Hi all,
first, thanks for wled looks like i’v ever looked for.
but i cant use it for now because I get a bootloop when I change #define DATAPIN to something else like 2
I tried every combination of Lwip, Arduino Core or Flash Size. No Luck, when is change DATAPIN my esp8266 (on a devboard nodemuc) quits with:

Hi, what is the new datapin you are trying to use? It might be a pin not allowed for use (because internal flash is connected), or it is a pin used by another WLED feature.

Hi, thanks for reply.
I tried Pin 3 and pin 13

4

Hmm, both these pins should work without issues… Clock pin is still GPIO0?
I will take a look at what’s wrong!

Clock is set to 14, but this also Happens when clock is set to 2.

Hi @boostar, unless you did change the line 24 in NpbWrapper.h from

#define CLKPIN 0

to any other value, you stick with GPIO. SCLK on GPIO is for SPI and not used.

Is there a reason why you move away from DATA = 2 and CLOCK = 0 ?

7

Hi…
No… there is no Special reason.
I think its because these were the default pins from a Sketch I used before.

I can change it, thats no Problem but i just to warnt to Report that because it could be a bug…

Hi,
I changed to pin 0 and 2 today. Works great.
Thanks a lot for wled, looks like it will make fun.

Hi I just tested pin 13 and pin 14 again and they work are great now
