Hey guys,

in case anyone else is one the search for a propper DAC for the teensy 4.x, i finally use the PCM5102A (PCM5102A Stereo DAC Decoder I2S 24bit Player Module) and connected as shown here ....

Hi again,

after fiddling arround with some i2c - dac modules, i managed to get an audio output from simple sketches. But in my mutch komplexer synth code i din't get it to work.

I wonder if...

thx. unfourtnatly the A* pins are already in use. have to think about it. maybe i will give it a try. thank you already

Hi Baloran,

could you please post a qick diagram on how you conected the pcm5102 to the teensy? have one here too, but a project designed on a teensy 3.5 with few pins left, so would be nice, if i...

Hi everyone,

was amazed to see that there is a teensy 4.1 with similar pinout as the 3.5/3.6. But after byuing one, i realized, that there are no dac outputs. :/

i'm having an almost builted...

Hi all,

im trying build an 8 voice (advanced) drum maschine with an teensy 3.5.

i started using the simple drum example sketch, within the audio library. after weeks of random sequencer stops,...

yep. thx mlu, exactly thats what i wanna try next. :)

Thx for the input Kurt, but thats far from, what i`m able to do at the moment. It´s disapointing at the moment for me, comming from arduino level to teensy potential, running througth hours of stuff...

@kurtE i suspect that :/

@mlu

when i upload the code and teensy rebboots, with sda connected:

- there is some MIDI Data recieved, cause the MIDINoteOn gets triggered, but not in the speed or accurancy as usual, after...

thx Kurt.

also for confirm, that it is not as easy as it should. so i don´t have to be only in doubt with my programmig skills ;)

Is there a simple way to tell the std wire.h to use only wire1...

Edit:
Compiling the code with uncomment Wire.h, but the library folder in the teensy folder and "include <i2c_t3.h>" produces this Errors:


"C:\Users\XMG P304...

Thank you two for your awnsers.

@Gremlin ok, so i think a have to recomplex and slow down things and try to get a working or non working version witch is more easily to understand.

@defragster...

Ok. Maybe i have to simplify my problem/question. Should it be possible to run a 5V Lcd via a level shifter at the SDL0/SDA0 pins and simoultaniously use Serial port Pin 0 for MIDI input?

Hi Guys,

hope someone can give me a hint, whats runnig in the false direction with my MIDI/Synth Project. I've startet to build an Audio Sythesizer (first with Arduino, but since a few weeks with...
