Thanks to everyone's help here my small project has progressed well. I now
had a completed (although very messy) prototype. For those who didn't read
my previous thread it is using an 8051 and a max232 to connect to a serial
port. I'm doing this project with a friend and he prefers to use C while I
prefer to use assembler. We have both written the software and both versions
work the same with only minor differences. I can see 2 problems with using
C. First, there is alot of extra assembly code added in that we don't know
what it does, if this produces a bug it could be hard to track down. Second,
it appears to use alot more of the rom. The assembler version is 757 bytes
and the C version is 1508 bytes. About 350 bytes is text in both, so the C
code is almost 3 times larger than the assembler version. The C version has
had quite a few hours spent on it getting it down to 1500 bytes where the
assembler version hasn't been optimised. 1500 bytes seams like a huge waste
when we only have 2k.
What does everyone think, which is better C or assembler? We are using SDCC.
