Dear Experts, Need some quick reference code in assembly which are supremely compact in size wise (as size of code is a big constraint now, so assembly is also the last option) used to convert an incoming serial ASCII line of digits to hex codes for computation. Roughly 4 ASCII digits, e.g. in ASCII: (31h 32h 33h 34h) to be read as 1234dec OR 4D2hex. Appreciate some really good helping hands! Cheers, James
You're under the false assumption that the CPU were using "hex codes" for actual computations. It's not. Numbers are just that: numbers. They are stored in memory in a way that some humans prefer looking at in a hexadecimal representation --- but that representation is not the actual number. You're re-inventing atoi(), which see.
