HI,
Now the time has come to complete my SID project witch is running for >5years 
Currently i’m working on the led matrix and i’ve a few issues. As TK mentions in the user manual i should use low current leds or a line driver like wilba. I’m going the line driver way bcause i have a ton of 3mm standard leds.
The only thing i can’t find is the “DEFAULT_SRM_USE_SINKDRIVERS” switch in the setup_*.asm of the midibox_sid_v2_044 firmware package. Am i looking at the wrong place or should i just insert #define DEFAULT_SRM_USE_SINKDRIVERS in the asm. Some help would be great.
Thank you in advance,
