Editing PCD8544.h (Solved)


i wanted simplify wiring 5110.  i have been using 5110 years , modified library @ outset i'm not sure did. new wiring is

8     9     10  11     12

clk din dc ce rst

and have lines 28 32:-

code: [select]
class pcd8544: public print {
    public:
 // pins can changed default values...
        pcd8544(unsigned char sclk  = 8,    /* clock        (display pin 5) */
                unsigned char sdin  = 9,    /* data-in      (display pin 4) */
                unsigned char dc    = 10,   /* data select  (display pin 3) */
                unsigned char sce   = 11,   /* enable       (display pin 2) */
                unsigned char reset = 12);  /* reset        (display pin 1) */


i nothing on display. don't know if have missed or have mental block. first assumed wiring wasn't kosher have installed little clock programme not use library, , works ok know shield fine.

ok, delete if knew how. problem, interested, order of pin assigment. last 2 lines of above code should swapped to

code: [select]

                unsigned char reset = 12);  /* reset        (display pin 1) */
                unsigned char sce   = 11,   /* enable       (display pin 2) */
