8051 Software and Utilities

I do a lot of work with the 8051 using the Keil C51 compiler and Hitex ICE, . Most of my support comes from the iSystem web site . For 8051 development there is a book "The C51 Primer" which is down-loadable from The QuEST page

The other main support tool I use is the Keil (UK) web site.

 

Software, Scripts and Utilities for 8051

 

The Software below has been scrounged from all over the place over many years. Some of it I have used and other bits were "on the shelf just in case". The parts I did not write I believe are in the public domain.

C51 data types and limits, pointer types (including memory specific)
 Keil D-scope (simulator) Functions and scripts   The Keil D-scope is quite a versatile simulator/debugger. I have written a few script functions for it. These include time and date stamps, formatted memory dumps, universal log to file functions. Link to D-Scope functions Whilst D-Scope is no substitute for an ICE it can do a lot of very useful work especially the non-IO intensive areas of your software.
 How to interface MS Source Safe and PC Lint to Keil uVision 2. this applies to C51,251 ans C166 How to use  8051 interrupts in Keil C51
How to write basic Keil C51 interrupt routines and match interrupt numbers to the MCU interrupt numbers
Atmel CC0*, RD2, the Security Byte and Emuulators

I had many requests for the 8051assembler floating point maths file. Today, I have managed to put the file on my website. You can find it here.
