This is an 8-bit AVR assembler I wrote for myself.

pip3 install rasm

See the help from the command:

rasm --help

This tool is written in Python 3. To run the tests you also need avr-objdump, colordiff, and xxd. On Debian or Ubuntu, these can be installed like this:

sudo apt install python3, python3-pip, python3-setuptools, python3-wheel, binutils-avt, colordiff, xxd

Install the package in editable mode:

pip3 install -e .

To run the test suite, just invoke:

./run_tests.sh
