Hi everybody
I need some help with the ESP32 Thing Plus DMX to LED Shield.
I tinkered a little around with some Scripts and was not able to get one of them running stable. All of them - if they even start - crashes after a few ArtNet frames. I tried the Examples from Sparkfun (i had to change some Lines of Code in all of them to get them running) and they failed all in the same way. After the first artnet.read-command the whole thing blocks completly. Sometimes the Code runs a few frames and then blocks too……and once or twice i got the whole thing running for about 5 Minutes, without changing the Code. A weird behavier. I tried several Powersupplys and Routers to connect to…nothing changes.
Ami missing a point or do i use the wrong Librarys? How can i check this?
Thanks for any Tips.
here’s one of my scripts and the Compiler-Output:

Read the 5 Channels of DMX Data coming from an ESP32 shield running Example 1
By: Andy England
SparkFun Electronics
Date: , 2018
License: GNU. See license file for more information but you can
basically do whatever you want with this code.
This example runs two servos and a number of LED's off of 5 DMX channels
Feel like supporting open source hardware?
Buy a board from SparkFun! https://www.sparkfun.com/products/15110
Hardware Connections:
Connect pan/tilt servos to pins DATA1 and DATA2, connect LEDs to CLOCK and DATA0. Connect a DMX XLR-3 Cable in between the Output and Input shields
