pots not reaching value 127

[matrigs]

i don't get it - i connected 3 pots 10k linear to my ain module and none of the pots ever reached value 127, stopping at about 123.

i used the most cheap pots but i guess that shouldn't happen anyway?

bad soldering doesn't come to mind - i checked everything a few times.

okay i got it - i soldered the ain module wrong by putting the bypass caps between the output of every chip and the connector to the core module...

if i could suggest maybe a few small improvements to the ucapps site? those pictures how to solder the ain module could be clickable and bigger - my mistake was caused by them and maybe a few else people might get confused by them? i could even make those bigger pics with my digital cam.

oh and there is a mistak on the ain site - there is written that you should solder the bypass cap between VSS and ground but in the pdf it's VDD and ground - that was my second failure....

cheers !

...  VSS is ground. Would make no sense to connect it from ground to ground  ;D

everything is possible for a noob :>

why couldn't they call it just ground instead of VSS ? :D

okay the most important thing is that i made it.

maybe i could make a tutorial for wiki on this ?

cheers.

I've fixed the typo.

Yes, a tutorial in the wiki is always welcome! :)

I would add a link from the MBHP_AIN to this tutorial thereafter
