converting ASCII to Hexadecimal format - Claro Louie - Aug 28 1:59:17 2008
Hi guys,
Can=A0I ask for your inputs with regards to my concern below?
What do you prefer in a routine that converts the ASCII to hexadecimal form=
at?
We have in=A0our communication=A0protocol that the host can read/write on t=
he memory given the address in ASCII format.
For ex. the host wants to read MEM1 address 61 (MEM1[61]). the host will se=
nd two bytes '6' & '1' and we need to convert and return a value 0x61 in he=
x.
Is it advisable to use 2 arrays? one for the ASCII and one for the Hex to p=
oint out the equivalent hex value for ASCII. OR are there other ways on how=
to do this without using arrays?
=A0Thanks and regards,
Claro

RE: converting ASCII to Hexadecimal format - "Redd, Emmett R" - Aug 28 4:10:30 2008
I usually add 0x30 to the nibble value if it is from 0x00 to 0x09. The offset is a
different number (that I cannot remember right now) for 0x0A through 0x0F.
