you know.. like with fastled :) i'd much rather keep you working on audio for t4 for now though

finally got the chip to make noise on an arduino.. didnt need the resistor/caps. it's the whole 'japanese format' thing lol. hopefully paul will port his library :)

not hot anymore! they dont seem burnt out afterall, but only work (still with poor sound) when i disconnect the clock. this is what happened with teensy+5102. hmm

ah look at that. doesnt seem like it would do much, 10 ohms. i'll see if that helps.

no smoke, just immediately really hot with or without load.. possibly they're ok: looking at this thread, seems like the software side isnt as trivial as i thought. also they're soic "PT8211-H", which i havent seen on the datasheets.

sorry to hijack. my teensy4.0 is happy with its PCM5102, but i've been trying to get PT8211 working on some other boards & they keep burning up. Are they 5v tolerant? datasheet says: power supply 3-6v, digital input high level max=VCC, digital input low level max = 1.8v, Input voltage max =...

I got my pcm1808 all wired up.. but no joy. did you have to change PassThroughStereo or FilterFIR at all? [edit] ah, right.. saw you were having problems too...

thanks- I got volume working with the 'amp' codeblock. "PLL mode", eh? my crackling was solved by grounding the dac's SCL- could imply something off with teensy4 mclk1? . ordering up a couple of PCM18.. i2s adc modules to hopefully finally get the full audio processing machine i've been hacking...

looks like you got it. i was having issues until I grounded SCL. havent figured out how to control volume though

that's a great thread- and info on spdif too. coax would be great too as there are audio interfaces floating around with that (i.e. vrm box) thanks!

zelda and guitar sketches sounding great via my PCM5102 module! listing some DAC schematics/options would make folks happy when they realize t4 has no audio pins or usb midi yet & doesnt work with their audio shields. :) has anyone tried SPDIF?

pin7 works with the example sketches. sounds horrible, but works.

there you go-thanks. seems like the download page would be a good place for that info. and my resolution this morning was to not jump the gun on new tech lol.

Hi -I just installed 1.47 teensyduino and I dont have USB Type options for 4.0(Midi, Audio, HID etc). they do show up for 3.6 and lower... windows 10, Arduino 1.8.9. thanks!

4.0 up and blinking! good to be back in the teensy world after an extended break. did you miss me?:rolleyes: so.. it doesnt give me any USB type options: i.e. MIDI, HID. is that intentional?
