Ok, I think I understand what's going on, now. @luni that link helped, thanks.
Fact: The `printf` family of functions need a `_write` function defined somewhere (this is how the current libraries do it, at...
I'll add another interesting detail: The code compiles and operates fine for Teensy 3 with the Teensyduino IDE but not with PlatformIO. With PlatformIO, it complains of the missing `_write`. Maybe PlatformIO is doing...
I should add: This works for Teensy 4 compilation but not for earlier versions, as the original poster stated about the unresolved reference to `_write`.
I wanted this same behaviour and found that this works for me, to replace `stdout`:
stdout = fwopen(&Serial, (void *cookie, const char *buf, int count) {
return reinterpret_cast<Print *>(cookie)->write(buf,...

Maybe some will find this useful. I've attached a FastLED controller () that uses DMX to output pixels. Specify the...
Thanks, @PaulS. I just released TeensyDMX v4.1.0 and it works fine on the Teensy 4. I tested send, receive, and RDM. It should also be able to retransmit as you wish, per your question above.
There's actually two...
I just released TeensyDMX v4.1.0: https://github.com/ssilverman/TeensyDMX/releases/tag/v4.1.0
Changes since v4.1.0-beta.2:
7- and 9-bit format support when using serial parameters to accomplish BREAK and MAB...
Check out some of the examples with TeensyDMX. It’s accessible through the Arduino IDE (or Teensyduino); just search for “TeensyDMX” in the Library Manager (v4.1.0-beta.2 is the current, but v4.1.0 will appear very...
Released TeensyDMX v4.1.0-beta.2 with a few fixes: https://github.com/ssilverman/TeensyDMX/releases/tag/v4.1.0-beta.2
The changes:
Fixed NativeEthernet interoperability by changing from a custom use of the PIT...
