SounDuke Posted December 3, 2005 Report Share Posted December 3, 2005 Hello, I've connected the leddigit as in http://www.ucapps.de/midibox_lc/midibox_lc_leddigits.pdf . Everything fine, the problem is that when connecting with 220 ohm resistor the dot pin to Vs of J3 the segments get dim and the dot lits very shiny. Kind of a short circuit? Maybe the segment display is Common Cathode? If so, it should not work with the default map in leddigits.inc, or I'm wrong? Thanks in advance Quote Link to comment Share on other sites More sharing options...
TK. Posted December 4, 2005 Report Share Posted December 4, 2005 Could it be that there is an error in the schematic? It seems that all blue lines are shifted (e.g., segment g should be connected to D0, not to D1) - the dot is normaly connected to D7Can you confirm that the LED digits at the right side only show garbage?Best Regards, Thorsten.

SounDuke Posted December 5, 2005 Author Report Share Posted December 5, 2005 thanks TK fixed it was an error in my pcb the resistor on Vs was bypassed by a bridge :) Quote Link to comment Share on other sites More sharing options...
SounDuke Posted December 7, 2005 Author Report Share Posted December 7, 2005 Hi Thorsten, maybe there is an error in the schematics for the leddigits. the right side is working well, but the left (4 digits including the status digits) show garbage. I'm testing it with live 5, yet I'm sure I made no wiring errors, what caught my eye was that sometimes the number of digits which are on doesn't match the number it should be (e.g. it should display 5, but only 4 segments are lit).

TK. Posted December 7, 2005 Report Share Posted December 7, 2005 As previously mentioned, there was a mistake in the schematic, did you take this into account?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
