Title: Sprit 87% Problem! (Solved, Sprit is awesome!)
Post by: fuus on Sat, 19 July 2014, 06:52:16: Question to all you master modders!:
I've put my sprit board together! All the LEDs work perfectly, and the keys all worked perfectly until I changed the angle of some of the switches to make the stabilizers (Cherry) work properly. Now when I press some keys it starts spamming keys e.g.,
when I press W: wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2ws x2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2 wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2wsx2ws x2wsx2wsx2wsx2w etc etc...

and i: i]k

any ideas what the issue might be? I've tried re flashing the firmware and I'm guessing it's now a PCB short I just have no idea which part of the board to start looking for it on!

Thanks, Fuus

Soldering error...

Both of the pins for w are touching the pins for sx2. Only one pin should touch.

Both of the pins for i are touching ]k. Only one pin should touch.

The switch may also have a problem.

You should de-solder that switch and try just connecting the wires together to see if it works properly after that. If it does, then just solder on a new switch.

Post by: fuus on Sat, 19 July 2014, 09:36:18: I've just ruled out the switch, shorting it with a paperclip caused the same issue.

Post by: fuus on Sat, 19 July 2014, 10:21:59: To add to the previous stuff I've now tested the diodes and they're absolutely fine too. I'm lost.

Post by: Matias on Sat, 19 July 2014, 12:48:05: Could be a defective PCB, or a short near the IC.

Post by: fuus on Sat, 19 July 2014, 13:16:46: No obvious signs near the IR with my own naked eye, I'm annoyed because the whole thing was working fine last night :confused:

Post by: swill on Sat, 19 July 2014, 19:12:50: Do you have a good camera? Please take a picture of the back of the PCB to show the 2, w, s, x column of your pcb matrix. Also, post a picture of your controller. A friend of mine has my 60% (which I think has the same matrix at the TKL on this part of the board, but I can grab it on monday to see if I can see any traces that might cause issues if there is a bridge somewhere.

When you type any of the other keys in that column 2, s, x, do any of them have problems or do they all work perfectly?

What do you mean by that?

Post by: fuus on Wed, 23 July 2014, 12:24:52: Plate only holds switch in on one side, so when I held them in to solder them they were at an angle unlike the other switches...

Post by: BlueBär on Wed, 23 July 2014, 12:47:28: I still don't know if I got what you mean. Can you maybe make a sketch of it or a photo?

So something went wrong whilst fixing this angle. Double check what you changed. I can't really see how good the joints are since you can better judge them from the side, but I see that the LED on the S key has not been soldered in properly and is lacking solder. It could be that some other joints need more solder, too.

Does the "wsx2" appear only while you keep W pressed or does it repeat even after releasing the key? If it only appears while keeping that key pressed, I think it has something to do with a broken diode or a diode that has not been soldered correctly. If it keeps repeating after releasing the key I would rather guess that the controller has a problem.

I know what yo mean about the plate. For me that was only the case on a couple of the stabilizer switches. I had to really hold them when I soldered, but I did not have any issues with the functionality of the switches...

Its hard to tell, but I can't see an issues with the solder job that would cause this. I still think there has to be something going on with the 2, w, s, x column though and if only 'w' is making this happen it is probably related to that switch somehow...

Sorry I can't really help more than that...

Before every PCB shipping, I do Test for All keys with tools. Hopely it was not the cause. ;)
