Hi everybody, i can't find the AN2131SC in my country, but AN2136SC seems to be reachable. I watched these chips in a datasheet and the pins 26 and 27 are differents in both, rest are identical.

My question is: There are some posibility to, in example, change some parameter in the source code to make the AN2136SC compatible with the MBHP_USB module? Thank you for your time.

hi again, a distributor has some chips possibly compatible with an2131:

uPSD3422E

uPSD3422EV

uPSD3433E

someone knows if these are really compatible? or someone knows if there are some other chip compatible?? Thanks for your time! ;D

I've no experiences with using other chips than AN2131SC (note that AN2131S is a different chip!)

Dangers are too high, that the firmware won't run without debugging.

Therefore I strongly recomment to search for a commercial MIDI interface instead - in europe such interfaces are available for 20 EUR, so that it doesn't really make sense anymore to build an own one

Best Regards, Thorsten.
