sASM

Simple Assembler

Uses a mnemonic definition file and a text assembler program to create a rom file, which can be loaded into Logisim.

Usage:

-h print this help screen
-m [path to mnemonic definitions]
-i [path to assembler file]
-o [path to output binary file]
-p print out loaded mnemonics
-d enable debug log

Example:

$ ./sasm -m ./test.txt -i ./test.asm -o ./test.rom1

See test.txt for an example mnemonic definition, test.asm for an example program and test.rom1 for the resulting rom file.
