Hi,
I have recently inherited a project that was originally done using an 8051. A few years ago the hardware was changed to use an 80C251SB but development continued using the C51 compiler.
There is no external data memory in the device. Is it possible to use the 80C251SB's larger internal data memory with the C51 compiler? We have uVision3 with C51 compiler version 8.09.
My bosses want to add PID and serial communication to the device (serial hardware is there but has never been used) and it looks like I've only got about 20 bytes left to work with.
you should, by now, have noticed how many threads have gone astray becuse somebody "understood a post".
Actually, this thread was going astray because you hadn't read and/or understood a perfectly clear post.
There were two pieces of information clearly stated in the OPs first post which, in your haste to criticise both his choice of processor and his posting ability, you completely ignored.

both defintions fit

1. a species of herring, Clupea sprattus, of the eastern North Atlantic. 2. a small or inconsequential person or thing.
...and neither definition is 'smoked sardine'. Nice to see you consulting a proper source for a change rather than grandma's recipe book.
