Hex variable to ASCII
Archiver
Posts: 46,084
Hi,
I have a word size variable Myvar=$FE00 and I need to convert it to ASCII hex
like "FE00". After it is converted, I need to store it to an external EEPROM.
Would a STR variable be best. Any ideas how I can do that?
Thanks,
Allan

There are several ways you might do this. I'd think about doing it this
way:
Stobyte var byte
Myvar var word
Eeadd var word
Stobyte = myvar.nib0
Eeadd=10 ' eeprom start address
Gosub stonib
Stobyte=myvar.nib1
Eeadd=Eeadd+1
Gosub stonib
Stobyte=myvar.nib2
Eeadd=Eeadd+1
Gosub stonib
Stobyte=myvar.nib3
Eeadd=Eeadd+1
Gosub stonib
... Blah blah blah...
Stonib:
Stobyte=stobyte+"0"
If stobyte<="9" then stonib1
' correct A-F
Stobyte=stobyte+"A"-"0"-10
Stonib1:
WRITE eeadd,stobyte
Return
Or you might want to use a loop and store the number backwards:
For i=1 to 4
stobyte = myvar & $F
gosub stonib
eeadd=eeadd+1
myvar = myvar >>4 ' destroys myvar
Next
Of course, if you wanted it the other way, you could set eeadd to the
top address and subtract one. Its as broad as it is long.
Hope that helps.
