	Don't you hate when that happens. One day everything is fine, and the next it isn't. I had my application working just fine. Then next time I did a revision that had nothing to do with the DMX library, it would not compile. Just to be sure that it wasn't something in my code, I loaded the DMXReadTest. That complile failed. The compiler output is attached. Any suggestions are greatly appreciate.

	Thanks for the report, it looks like the changes in the ESP32 board package are incompatible with the latest version of the library. On their issues list on GitHub a user suggests rolling back the ESP32 board package to v3.0.4, and then using v4.0.0 of this library: https://github.com/someweisguy/esp_dmx/issues/186

	Oh Geeze. I have enough trouble dealing with the code errors I make. It is very frustrating when things shift underneath you and cause problems. This is not the first time this has happened. It compiled fine with the ESP32 core rolled back to 3.04 and leaving the ESP_DMX library at 4.1.0 I am just going to have to start adding a comment section to my code showing the revisions of the core and the libraries used so I can at least have some idea of a environment that worked. Thanks very much.

	No problem, and understand the frustration. One way you can encapsulate the versions needed for a specific project is to use the "arduino-portable" solution folder. https://www.visualmicro.com/page/How-to-Encapsulate-a-Board-Package-with-a-Solut... NOTE: When using this approach with the ESP32 board package, the solution folder structure should be placed as close to the root of the drive as possible (paths over 30 chars to the solution folder can become problematic). This allows the board package, and all libraries to be captured within the solution folder structure, so you don't need to remember them when moving between different solutions.
