Hijacking OEM hardware - '51 EFI project

[Sandy]

If you are looking for low cost 51' tools, their was a guy out of canada,
his company was Dunfield Devlopment, and has a buch of good, low cost
compilers, and other 51' related tools. I have the freeware version from a
couple of years back with the complete source for the compiler, assembler,
and optimizer. I was at the time trying to do some 51' stuff so I figured I
would hack a compiler as well... Go figure.

Alex - looks like you and I are paralleling each other to some extent. As
for the analog interface stuff - the '552 board (actually the chip itself)
has 8 channels of A/D. I just averaged this over several measurements (have
not yet experimented with the optimum number - initially used 4) 

There are a fair number of '51 debuggers available free. Intel has one that
I have downloaded. The LM1949 - National will supply free samples - takes
them a while. 

The C compiler is the old "small C" written by Hendrix (not Jimmie I hope)
for the '86 and ported to '51. All source code is supplied. It is limited,
but more than I am used to. 

This is too big a project to eschew the tools that have been built for the
purpose. We have plenty of computational power. Write in C then hand
optimize.

your uC is 552 
or 562 ?). 
 What kind of C you are using ? 
Better try to use assembler than C , you will be faster . 
You have any debugger for your board ?

. 
If anyone is thinking to start a common project with '51 uC I'll be glad 
to be on the list . For the beginning , I can make public my development 
system for '51 uC ( which can be expanded to '552 ) 
I have schematics , gerber files and all the software for this system
