OK, now i am planning to multiply two variables, AmpHour and Volts, then i call print_Char to have human readable character and transmit serially to my RF module (view in Hyper Terminal). I'd written a very simple code for it, so i might need your guidance and see is it correct. Thanks.
Where the mov16 is declared as:
Rich (BB code):
;16 bit register 'a'
WORD aa
;16 bit register 'b'
WORD bb
WORD energy
multiply:
mov16 AmpHour,aa
mov16 Volts,bb
call mult16 ;multiply AmpHour with Volts
skpc ; remainder > 0.5 ?
goto store_energy ;store as energy
inc16 dd+2 ;yes, round up
call print_Char
store_energy:
mov16 dd+2,energy
Rich (BB code):
;====================================================================
; 16 bit macros (Big-Endian)
;
mov16 MACRO src,dst
movf src,w
movwf dst
movf src+1,w
movwf dst+1
ENDM
