#Arduino uno r3 programming serial

make program=blink upload - upload the program to your Arduino board.

make (or make blink.hex) - compile it to a hex file.

The makefile is available towards the end of the page. I find it easier to understand and maintain. And as with other "prepackaged" solutions, like oh-my-zsh, I prefer to start from a small base. NOTE There is already a popular Makefile project for Arduino, however that one relies on the AVR Libc project.

NOTE If you skipped this step, be sure to replace any occurence of /dev/arduino-uno with /dev/ttyACM0, and prefix all avrdude calls with sudo in the followup Makefile.Īlso you'll see a reference to picocom (program used for serial communication with the board) in the Makefile I use, and it should work but I haven't tested it yet. If you do the symlink, be sure to also include the OWNER directive otherwise every time you upload the new program to your Uno you will have to call avrdude with sudo. KERNEL= "ttyACM0 ", SYMLINK+= "arduino-uno ", OWNER= "mhitza " Because I wanted a more intuitive device name (and the fact that it took me some time to find out what device name it had in the first name), I wrote an udev rule to map my Uno board to /dev/arduino-uno. When connected via USB my Uno would have it's serial interface mapped to /dev/ttyACM0. Do note that I'm using a Linux box, and in case you're on another operating system you'll be on your own with the setup/configuration of these tools.

But you might research on your own the alternative setup based around the AVR Libc project.įor the setup I use you need: avrdude and avra. There are two major options for the task (of which I'm aware of), and the setup I've settled on is accidental in This is an attempt to aggregate all those sources in a centralized document, with two simple example programs. There are a few different sources online that describe the ways that you can program Arduino Uno/ATmega328P in assembly,Īnd in the last couple of days I've had to switch through most of them just to get the basic setup and initial programs working.
