Interrupt conflict about esp_dmx

[someweisguy]

Thanks for the praise and thank you for submitting this issue. And thank you for the excellent troubleshooting you have done so far.

I only could set between Flag 1 and 2. And that didnt fix the issue. After Flag3 it did not receive DMX packets anymore.

This sounds right to me. I don't recall exactly how this behavior is supposed to work off the top of my head but this sounds about right. If I recall correctly, any interrupts above flag 3 must be written in assembly. The interrupt service routine for this library is written in C. The Assembly/C interrupt flag behavior is a quirk of the hardware, not something that this library defines.

Btw is there an option in your code ( which i did not see where) to define that the driver should be used in IRAM? I guess its the default ? Or should we define it somehere?

Due to the way Arduino works, your version of Arduino will automatically place the DMX driver in IRAM. This may change when Arduino officially supports ESP-IDF v5.1 but the current version you are using will place the driver in IRAM. On Arduino, this setting is not able to be changed.

Is there any code that you are able to share? I think that is the next step that will be needed to help with this issue.
