Well, ya have to start somewhere and here I am. I have completed this tutorial of how to build a 15x7 scrolling display sign, using the standard 16F628(not 16f628A) and is very stable. I am having a difficult time grasping the know how of changing the asm. I know that i cant just make up something to put into this asm and make it work. I tried that...it worked but garbled up.:) So, my question here is, Is there anybody willing to help me with this 1 thing im trying to do? As you will see below in the .asm i have provided, there is an effects switch (sw6). I want to do something with this, but, i have to edit this area along with another? Leave your comments or questions and I'll follow up. Later.


character
retlw 00


;sw6 = EFFECTS


sw6 NOP
goto sw6




write bsf status,rp0 ;select bank1
bsf eecon1,wren ;enable write
movlw 55h ;unlock codes
movwf eecon2
movlw 0aah
movwf eecon2
bsf eecon1,wr ;write begins
bcf status,rp0 ;select bank0
writeA btfss pir1,eeif ;wait for write to complete
goto writeA
bcf pir1,eeif
bsf status,rp0 ;select bank1
bcf eecon1,wren ;disable other writes
bcf status,rp0 ;select bank0
retlw 00
