Not working on Teensy 4 #21

Can't get DmxSimple working on Teensy 4.

I'm using the latest version of Teensyduino, DmxSimple, using the fade.ino example. With the same setup all dmx lights are properly fading using a Arduino Uno or a Teensy 3.2. Everything works as expected.

On Teensy 4 the code is compiling and uploading but all lights stay black.

Hi Jonas, here working on a project and we had the same problem on teensy 4.1 . I think there are issues about 3.3V only of teensy 4.0 and 4.1 and some types on the library. Now I'm using a teensy 3.5 and work good for me.

I hope someone look at the source code and fix it, I'm not sure I'm able to do it... bye

Hi there, i also use the pin 38 on a teensy 4.1, and i can confirm that it is not working. Nothing on the output (i used an oscilloscope). I used all the serials port for something else, so i really need to use a digital pin. I will try to add more details (eventually propose a correction if i understand the problem).

Does it work with some specific pin? Thanks

I moved to another lib. Teensy dmx that use a Serial port.

@PaulStoffregen have you seen this issue? I've moved back to Teensy 3.2 today because it works. cheers

@dimitre - Yes, I am aware. DmxSimple is a low priority because other DMX libraries work on Teensy 4.0 & 4.1, with better performance than DmxSimple.

Hi @PaulStoffregen , do you have some different libraries to advice for working with Teensy 4 ?
