USB-I2S-TDA1543 kit
 
I just received audioworkshops AW-D3 kit. http://www.audioworkshop.com.hk/index_en.htm

After reading posts about problems here and in Audioworkshops forums about the J2 jumper settings for I2S operation - I was wondering has anybody else built one of these?

I nvestigated & came up with a plan, which might work.

I decided that I would dispense with the options allowed by the jumpers and wire it permanently for I2S mode & self powered.

This is relatively simple for I2S - just leave out R7 100k res which feeds 3.3V to FSEL (this leaves FSEL low=I2S mode)

This is not so easy for self powered mode - PSEL is connected to 3.3V and this line has to be cut and routed to ground (PSEL low=self powered).

Has anybody tried this - what do you think - would this solve I2S issues?

John
