hi everybody

i make a pcb with the memory the core and the out only but on the out only schematic here http://www.ucapps.de/mbhp/mbhp_iic_midi_out_only.pdf

there isn’ t J3 port to configure the adress

i would like to know if i have to add it or if i can chain 4 “IIC module out only” without J3 port

thank you

if you’re only using one IIC module, then it’s already addressed as the first by the grounding on pins 12/13 of your IIC PIC.

are you etching this pcb yourself?  if not, i’m making a core/4xIIC/8x bankstick pcb and it might end up being cheaper because there will be a run of them available.  you only have to use the parts you want.

the only problem is i still haven’t had a test pcb made.  i expect to finish it up this week.

i’m hoping soon.  i think this week i’ll be able to have a prototype made.  i don’t know a price yet but it will be relatively cheap.  i would guess not more than $15 or $20 USD, and i think that’s a high estimate.
