d2k Posted May 5, 2003 Report Posted May 5, 2003 Hey TK...I'm working on the encoders/led rings for the LC box - for the LED rings test f/w I just get the first 8 LEDs of all 8 rings lit, then the last 3 LEDs lighting up sequentially from one ring to the next...Is that correct? The description say's various patterns will be displayed...Best...Dan
TK. Posted May 6, 2003 Report Posted May 6, 2003 Hi Dan,not this isn't correct. The shift registers have to be defined in the main.asm file: ;; used by lc_ledrings.inc LEDRINGS_SR_CATHODES EQU 8 ; shift register with cathodes of the 8 LED rings LEDRINGS_SR_ANODES_1 EQU 10 ; first shift register with anodes of the 8 LED rings LEDRINGS_SR_ANODES_2 EQU 11 ; second shift register with anodes of the 8 LED rings note that here the shift registers are counted from 0. This means: number 8 is the 9th shift register in the chainBest Regards, Thorsten.
TK. Posted May 8, 2003 Report Posted May 8, 2003 Hi Dan,ok, with a PIC16F core you have to connect the LED rings to port J7, it should work w/o problemsBest Regards, Thorsten.
