Screaming_Rabbit Posted January 19, 2008 Report Share Posted January 19, 2008 Is using 11 LEDs on a DOUT going to lead to issues?It looks to me, that you're driving 10LEDs from the DOUT. - It makes more sense to hook the Power-LED to the 5V side of the PSU.Greets, Roger Quote Link to comment Share on other sites More sharing options...
dj3nk Posted January 21, 2008 Report Share Posted January 21, 2008 It looks to m e like 8 Leds. 2 are for midi in /out. They should be connected to a ltc. Power led like screaming rabbit said Quote Link to comment Share on other sites More sharing options...

cimo Posted January 21, 2008 Report Share Posted January 21, 2008 from main.asm; For MIDI activity monitor: define the DOUT pins for the Rx and Tx LED #define DEFAULT_MIDI_MONITOR_ENABLED 1 ; if 1, the Tx/Rx LEDs are enabled #define DEFAULT_MIDI_RX_LED 0x40 ; DOUT SR#9, pin D0 #define DEFAULT_MIDI_TX_LED 0x41 ; DOUT SR#9, pin D1simone Quote Link to comment Share on other sites More sharing options...
