GPIO / PIN Number ?
my lights dont go on. i compiled and flashed ok. i wanted to try the neopixel-Test-example and the source says
define pixelPin 2 // make sure to set this to the correct pin, ignored for UartDriven branch
so i have the UartDriven branch, what pin do i have to use? i am a little bit puzzled
i read in the readme of the neopix lib:
For the exp8266, only the TXD1 pin is supported due to the hardware uart restriction and this argument is ignored.
so i am using an ESP12, do i have to gave up my serial monitor an use the TXD pin for the LED-Strip? i will give this assumption a try ...
i checked the pinout here: http://makernews.info/featured/2015/09/esp8266-pinout-the-esp-01-and-esp-12-on-nice-new-pin-out-diagrams.html
and give gpio2=TXD1 a try on the esp12... doesent seems to boot with LEDs connected....fiddling...
right pin is TXD1=GPIO2 ok. but when leds are connected, it wont boot. when i connect after boot, esp crashes.. wifi interface was reachable (little slow, but all worked)
i have a powersupply-setup on breadboard, which worked with same hardware before..
hmmmm so far...so ....
you stated this in the readme:
Currently the WS2812 LEDs must be attached to GPIO2,
I've found best results to use this as a level converter - 74HCT245N.
ok, pin-number found, but i did not have a level converter... but i dont think this makes the esp crashes, or ...?
