Timesquared watch help

by SparkMike77 on Sat Jan 12, 2013 6:52 pm

While assembling the Timesquare watch I made an error that I believe should be correctable but I can't quite figure it.

While soldering in the LED matrix I think I must have damaged one of the through-hole connections, specifcally the 3rd pin from the battery, on the side with the Set Button. Everything else on the watch works brilliantly, except the 3rd row of LEDs does not light at all.

I'm am pretty sure it's my shaky hands that caused the issue, but it doesn't look like I've bridged any connectors, so if I can figure out what pin in the micro or a specific other point I can solder to I believe this should be bypass-able. Even without the one row I'm quite fond of this little watch so I would very much like to fix my error.


Thanks in advance,

M.

I'll track down the schematics. In the mean-time, if you post some clear photos of your board we'll take a look.

Unfortunately I don't see any issue with the board once assembled, I damaged the through-hole plating (I think) at the pin marked with the arrow. Either way I need to know where the pins that drive the row of LEDs are supposed to connect to, specifically the one on the side with the SET button.

Still working on locating the schematics, it is a new product and they haven't been posted to the repository yet.

Thanks Phil!

So the third row is controlled by LEDCATHODE2 which is pin 25 on the ATMEGA168.

I can't load either the .brd or .sch in eagle, says it's not a valid eagle file (newest version, downloaded from site on Freemium) but I cn tell you that running a wire from the pin in the picture I sent to pin 25 produces nothing at all. the buttons won't even wirk with that connection in place.

I have no trouble loading it in Eagle 6.3.0. Here is a png of the schematic:
