Install an avr toolchain (if you're on OS X, use [`brew`](http://brew.sh) to install `avr-libc` from [osx-cross](https://github.com/osx-cross/homebrew-avr)).\n2. `cd firmware`\n3. `make`\n4. `make flash` and `make fuse` as necessary to program your MCU (you'll need `avrdude` for this, `brew` has it)\n\n### Common issues:\n\n---\n\n`avrdude: no programmer has been specified on the command line or the config file`\n\n`avrdude` needs to know what kind of programmer you're using. You can uncomment/edit one of the `PROGRAMMER` lines in `firmware/Makefile`, or add a `default_programmer` directive to your `~/.avrduderc`.\n\nFor more information, check out [`firmware/Makefile`](firmware/Makefile).\n\n---\n\n`avrdude: AVR Part \"attiny48\" not found.`\n\n`avrdude` can't find a part config for the attiny48. You can resolve this by appending [`doc/attiny48.avrduderc`](doc/attiny48.avrduderc) to `~/.avrduderc`:\n\n```\ncat doc/attiny48.avrduderc \u003e\u003e ~/.avrduderc\n```\n\n---\n\n## Porting to different hardware\n\nIt's possible to configure this project for different AVRs. Check out [`config/attiny48.h`](firmware/config/attiny48.h) to get familiar with the required definitions and application considerations.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnumist%2Fis31io7326_clone","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnumist%2Fis31io7326_clone","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnumist%2Fis31io7326_clone/lists"}
