Need help running the handyboard in assembly language

lugnet.robotics.handyboard

Hey all.  I am a high school student in an engineering/robotics class at a
fairly advanced level.  I have gone through the steps of programming for the
LEGO RCX, and have moved to become a strong writer in the C programming language
and control mechanisms for the handyboard.  But now due to limitations of even
the C language, I need to move to programming in assembly language.  I
understand the basic structure of the language and the notations and mnemonics,
but when it comes to assembling the code and transferring it over to the
handyboard, there have been numerous roadblocks and I am about to pull all my
hair out.
Here is a list of my steps taken and roadblocks hit:
1.) I have successfully downloaded p_code.s19 to the handyboard using dl.exe
2.) I have written code both of my own writing and example code taken directly from Fred G. Martin’s Robotics book. (Only in frustration as I will describe later)
3.) I am not operating in full DOS mode due to restrictions of the teacher, but if necessary I can switch over.  But I can run the interactive C program in the command line shell.
4.) My first problem is assembling the .asm file to be downloaded to the handyboard.
5.) AS_11.exe will not run.  I have tried to run it using both the command line tool and in windows and it will not open.  Since I cannot run in DOS mode I resorted to other methods
6.) I switched over to my macintosh computer using OS X. with Classic support but the program will not run.
7.)  I have gone to newtonlab.com and used their online ICB compiler.  The
mnemonics like LDAA and ORG converted but the data and location like #$80
trigger the statement “Unrecognized Mnemonic” when the ICB assembles the code.

Could someone tell me step-by-step what to do.  If switching to full DOS mode is
necessary I can find a way.  I want to be able to switch between C and assembly
languages within a running program to facilitate the mobility of the robot if it
is possible in any way.  Any form of help would be greatly appreciated.  If
there is an alternative to switching to DOS that sort of information would be
appreciated.
Thank you

Polaroid and Handy Board malfunction

Hello:

we have aquired all sort of sensors for Mobile robot application and with them
the MIT Handy Board and its expansion borad.
Our problem is when we try to use the Polaroid 6500 smt sonar borad with the
expansion board of the HB. After all connections were made according to the
manual of both the 6500 sensor and the expansion HB, at the the time of turn on
of the board The power diodes on the expansion board heated up and the Q1
transistor of the polaroid 6500 board was fried. We have checked all possible
reason of mistakes we might have made but none was found. Is there something
missing that we did not get with the package that should made us aware of some
precaution, or maybe some connection or variation of what was written in the PDF
manuals?

please if anyone can help on this issue, reply  to maged.najjar@balamand.edu.lb

we are holding any furthur try with another polaroid 6500 and HB until we get
some clue of what went wrong.

Thank you

Wow, I thought this list was dead.

Hmmm. You're missing two key bits of information :
1) Do you want to individually control each LED's brightness?
2) How often do you wish to change the brightness?

If you are attempting to make a television like display its a lot harder
than if you're making  simply a LED sign.

hi.

i'm working in a project in which i'll need to control the brightness of about
700 leds.  i've just begun to research solutions - and i'm not sure the hb is
the right microcontroller for the job, but i thought perhaps an hb user on
this
list would have some relevant experience and could perhaps point me in the
direction of the right hardware/software combination.  it seems as though i'll
need multiple microcontrollers, and additional hardware to manage the
control of
a large numbers of leds.

the MAX6954 4-Wire Interfaced, 2.7V to 5.5V LED Display Driver with I/O
Expander
and Key Scan made by maxim-ic was suggested as a possibility - if anyone is
familiar with it.

http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3410

separate but related, i'll need the software running on the mc to be able to
return the current time, down to seconds.  i know system time is available on
the hb, but gets reset everytime the device is rebooted.  so - if there
are any
suggestions regarding a solution for this piece as well it would be much
appreciated.

thanks in advance,
claudia
