SparkFun DMX Examples not working

Development Boards ESP32
1

Hi! I’m missing something and I don’t know what, so I thought I’d give it a go here. Although I’m a software developer, it’s my first time playing around with the ESP32 or development boards in general, so bear with me :slight_smile:

I’ve bought the SparkFun Thing Plus and SparkFun ESP32 Thing Plus DMX to LED Shield in an attempt to do some stuff with DMX lighting. I got the SparkFun Thing Plus examples (light blinking, bluetooth connection) to work perfectly, so I know I have my Arduino IDE and connection to my board setup right.

Next step for me is to try and get one of the examples from sparkfun/SparkFunDMX to work, but here I’m running into issues quickly. I’ve added the libraries according to SparkFun ESP32 DMX to LED Shield - SparkFun Learn and I’ve put Example 1 - DMX Output in Arduino IDE. I’m trying to just verify the code, but I quickly run into errors not in my code but having to do with HardwareSerial used by the SparkfunDMX code. I’ll put the errors below. I’m a bit lost as to whether I’m missing a step, whether these errors could be caused due to version mismatches between the libraries used or whether there’s a whole different cause. I hope anyone can give me a push into the right direction.
