I want to write a program to convert the hex to ascii by using mplab.
eg. convert 0xAF to 0x41 and 0x46 (convert number in file register 0x40+i to ascii and save it in 2 file registers- 0x50+2i, 0x50+2i+1, where i= 0,1,2,3,4,.....)
Please HELP! THANKS!
Now, I only know how to convert 0x0? (from 0x40+i to 0x50+i) with this code and how can I change it to satisfy my wants>
CODE as following:
Main: movlw 0x1 ; Initialize array starting from 0x040
movwf 0x40, A
movlw 0x4
movwf 0x41, A
movlw 0xA
movwf 0x42, A
movlw 0xF
movwf 0x43, A
lfsr 0, 0x040
lfsr 1, 0x050
movlw d'4'
movwf COUNT,A
MainLoop: movff POSTINC0, InputConvertHexToASCII
call ConvertHexToASCII
movwf POSTINC1
decfsz COUNT, F, A
bra MainLoop
bra $
ConvertHexToASCII: movlw upper ASCIIList
movwf TBLPTRU
movlw high ASCIIList
movwf TBLPTRH
movlw low ASCIIList
movwf TBLPTRL
movf InputConvertHexToASCII, W, A
addlw 0x01
movwf COUNTSub, A
Loop: tblrd*+
decf COUNTSub, F, A
bnz Loop
movf TABLAT, W ;Result in WREG
return
org 0x000200
ASCIIList db 0x30, 0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x41, 0x42, 0x43, 0x44, 0x45, 0x46
end
