Teensy 4.0 MIDI circuit

[hoho]

Hi,

It's probably asked and answered multiple times, but I can't create a search query to find it.

Is the circuit from https://www.pjrc.com/teensy/td_libs_MIDI.html (the first one with 6N138) still the recommended one to use with Teensy 4.0?

Thanks.

As the Teensy 4 is still 3Volt and the MIDI-electrical specs didn't change, i'd assume yes, the same circuit
And yes, it was answered multiple times.

Thanks!

Two things have made me wondering: 5V on pin 8 of 6N138 and the lack of T4 mention on that page.

Makes sense to update that page and add T4 to the table. So that people like me don't increase the entropy .

I've updated that MIDI library page.

Wow, 4.1?
Pretty cool .

Yeah, as if 7 simultaneous serial MIDI streams isn't enough!
