Gluon is a Serial Bootloader for AVR ATtiny

The ATtiny102 and ATtiny104 are Atmels newest addition to the AVR ATtiny family. They are a bit different to most of the other devices in that family, since they are based on the AVRTINY CPU core, which was so far only used in the ATtiny4/5/9/10/20/40. I have previously done several projects on the ATtiny10, so I was naturally excited to see another addition to this family. Both new devices are clearly targeted at the lower end, with only 1kb of flash.

Two interesting new features compared to the ATtiny10 are self-programming capability and an integrated UART. Naturally, this asks for a serial bootloader. Since no bootloader is available for this device I set out to work to work on one.

Right now it is able to upload and execute user programs on ATtiny104 and ATtiny85, but it is far from being optimized. I stopped working in Gluon for various reasons, but may be picking it up again at some point.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
