S/PDIF via serial revisited?


#1

Hey i read the threads with at least a few tidbits of info on digital audio/interfacing several AXOs. And looking at the STM32F and what @johannes said about it, it seems like our beloved microchip is totally capable of native S/pdif i/o handling. see this application note https://www.st.com/content/ccc/resource/technical/document/application_note/group0/c5/67/84/35/7e/4c/4c/19/DM00431633/files/DM00431633.pdf/jcr:content/translations/en.DM00431633.pdf

i am still digging into this totally overwhelming pdf but was wondering if maybe in the meantime anybody else took some endeavours in this direction? how would i even start about it, any pointers? do i have to route the output of those STM functions to one of the digital/serial i/o's ? probably open a serial connection, then write a script that call teh s/pdif functions? man i realize am in way too deep. no clue whati'm even saying. if anybody is desperate for a developing job, i have some money to spend haha.

Look at the experimental Axoloti firmware on Github- you’ll see the SPI code.

Sending data between Axoloti is easy. Trying to do it at sustained audio rates, without glitches, probably not easy.

Hey man can you point me to the experimental github? i'm not too familar with git and can't find it on the regular axo one...

edit. nevermind i found it :crazy_face:
