#A few notes this is running the real 16bit DOS rasm executable inside of DOSBox. This means DOS limitations apply. Make your filenames really short (8 characters or less). To read more about the restrictions, visit [http://en.wikipedia.org/wiki/8.3_filename]

These instructions have been tested on Mac and Ubuntu (donlanes). You will need some kind of a serial port to them to work. If you have questions, please ask me (isaac).

I will likely continue to work on the toolchain, and will send out an email if I add something notable. prog8051 is a bit sketchy. I haven't tested it much. I will add version numbers to my toolchain if I release more than a few versions. #Instructions

sudo apt-get install dosbox python-serial 

mkdir ~/6.115 

cd ~/6.115

wget http://mit.edu/~igutek/Public/6.115_toolchain.zip

unzip 6.115_toolchain.zip

echo  "export PATH=~/6.115/tools/bin:\$PATH" >> ~/.bashrc

Test this by typing rasm test.asm

It should print something like this:

Executing DOSBox...

-rw-r--r--  1 isaac   44 Feb  9 17:55 test.obj

Additionally, you can type

make program

To upload the program on the RJ31P (is that what it's called). ##Serial Port Settings For this to work, edit the Makefile and change the serial port to be the correct one for you machine. To find out, first type

ls /dev/tty*

Now plug in your serial port, and repeat the command. The item that shows up is the serial port. ##Modifying the Makefile for your own code You can modify the Makefile to change which asm file it assembles by changing the SRC variable.

Just open the file and replace SRC := test with SRC := myfile (without the asm). Your file must be named myfile.asm ##Plain Old rasm If you want, you can also just use rasm as documented in the lab

##prog8051 If have also included a program I wrote, prog8051 which will upload an .obj file the the board if it is in monitor mode. To use it, type prog8051 -o myfile.obj --serial-port /dev/thecorrectserialport

To see the prog8051 syntax, type

prog8051 --help

You can edit prog8051_config.ini and change the default serial port that prog8051 uses. This way you can program simply by typing

prog8051 -o myfile.obj

#Mac Instructions

  • Copy DOSBox.app into /Applications
  • Make a symlink to /Applications/DOSBox.app/Contents/MacOS/DOSBox from ~/6.115/tools/bin/dosbox
ln -s /Applications/DOSBox.app/Contents/MacOS/DOSBox ~/Dropbox/Classes/6.115/tools/bin/dosbox
  • Follow the general instructions above, but Instead install pyserial with the following command
sudo easy_install pyserial
