Ledring trouble

[tHe_IkkE]

Hello everyone!!

I [glow=red,2,300]finalay[/glow] started actual soldering on my MB_LC!

So far the good news....

The bad part is this: I accidently mounted all 24 LEDS in the wrong direction. I've made a matrix for 4x12 LED's (It worked...) but looking at the schematics from TK I found out they were turned the werong way.

My question is this:

Would it be enough to just switch the bridges and resistors' places to get this to work (I will solder the other 4x12 matrix wrong to :)) or do I have to desolder it all ... :-/

Thanks in advance...

Anyone?? :-[

I'd really like yo know wheter I have to desolder it all or can just change some stuff in the main.asm en replace the bridges with resistors and viseversa

thnx

Hi,

it won't help to exchange the bridges by resistors and vice versa, but a simple change in the application software will help. Just only the polarity has to be inverted, this means: open "lc_srio.inc", and add

        comf      MIOS_PARAMETER1

before every "call MIOS_DOUT_SRSet" instruction.

(I've counted 12 of them...)

Thereafter rebuild the .syx file like described under http://www.ucapps.de/howto_tools_mpasm.html

Best Regards, Thorsten.

thnx TK!

I'm really releaved I don't have to do it all over again....

Hope to post some progress soon.
