|Application Note 0003
||March 17, 2013|
The following article has been written by an unknown master,
probably an enthusiastic ASEM-51 user. He has illustrated it with
screenshots and originally posted it on
on April 3, 2007. It was useful, detailed, comprehensive,
and easy to find with search-engines.
In May 2009 I found that this site had completely changed,
but the collected articles had been moved to
However, the author's real name could no longer be retrieved,
and (even more annoying) the screenshots were lost in space.
Recently I remembered that I had saved them somewhere, years ago.
So I was able to restore the whole article, update, polish, and
finally republish it on my own website, supposing the author's agreement.
If he should ever read this, I'm looking forward to his mail.
ASEM-51 step-by-step Installation on Windows XP
Last time I wrote an
installation for ASEM-51,
a two-pass macro assembler for the Intel MCS-51 family of microcontrollers,
using the batch file INSTALL.BAT.
For someone who do not like anything that is running automatically, or things
are not quite clear, here is a step-by-step installation guide for ASEM-51.
The files we require are
1. Create a new directory on your harddisk, e.g.
C:\ASEM51 and unpack
all files of the ASEM-51 package into this directory
(see Figure 1).
2. Unpack MCUFILES.ZIP into a directory (see Figure 2).
Move the *.MCU you want to
C:\ASEM51\MCU (see Figure 3).
Here I move the P89V51RD2.MCU only.
