Changing LEDS freezes I2C connection #692
I‘m currently using esp8266 as a master and arduino nano is a slave, i seems to be fine when i leave it idle, but when there is some light effects going on on my arduino nano the connection freezes and never recover.
I2c makes heavy use of interrupts on the nano - which doesn’t mesh well with ws2812 style led timings - https://github.com/FastLED/FastLED/wiki/Interrupt-problems
