Re: SD Press - Under the Kimono
The next step is the replace the green LED ring with a ring of WS2811's then change the patterns for functions. i.e. pulse orange with the bed/hotend it getting up to temp. Flash red for errors etc...
That is brilliant. Would you run the new light ring off the atmega or attiny chip?
Second question, have you done any probing or circuit trace to determine the number of wires that connect the atmega and attiny chips? In the firmware I only found the one wire, PRINTING_PIN = PIND4, which activates the LED ring through the attiny.
I also see pins for home, pause, and cancel in there. Interesting ...
#define PRINTING_PIN PIND4 // OUTPUT tell ATtiny we are printing
#define PRESS_HOMEXY PIND5 // INPUT tell firmware to home x/y
#define PRESS_PAUSE_PRINT PIND6 // INPUT tell soliprint to pause
#define PRESS_CANCEL_PRINT PIND7
