Thanks PaulRB
Had to go through the list of forum points to check what I may have done.
For those that may stumble here - Forum Recommendations
http://forum.arduino.cc/index.php/topic,148850.0.html
I thought by posting the snippet of code I'm working on would make it easier as the rest works fine.
But to point #16 my code is below
For point #15 -
Rather than posting what I think are the options, I'll state my issue as
I'm sending in either a char as "0xff00ff" or as "rgb (50,100,150)" to my board using MQTT and the fill_solid in MQTT compaints about a unint8 or CRGB. I've tried to send it the rgb codes and using a loop to put the r,g,b values there. It's creating a watchdog soft reset. If I disable the soft watchdog, it triggers a hard reset.
Point #13 - Forum Etiquette - This question is specific to the fastLED function so I created a seperate topic in the LED section as my previous question was related to MQTT.
"
Point #6 - I think my topic is descriptive
Point #7 - Yep, used the code/code
Point #10 - My spelling may be poor at times, but I try to follow sentence structure.
Point #11 - Equipment is a ESP8266, WS2812B, 5V adapter, an SMD level-shifter.
"However, with coding problems, if possible post a "minimal" sketch that demonstrates the problem "
I'll be sure to follow these closer where applicable.
