tHe_IkkE Posted April 15, 2004 Report Share Posted April 15, 2004 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...

TK. Posted April 26, 2004 Report Share Posted April 26, 2004 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.htmlBest Regards, Thorsten.
