Programming the ATtiny10
Programming ATtiny10 with USBASP and avrdude
Notes on programming a small (SOT-23-6) and cheap (44-46 cents at qty 1) microcontroller, the Microchip ATtiny10 in a Linux environment using C and a USBASP programmer. The ATtiny series uses TPI (Tiny Programming Interface) instead of ISP (In System Programming) so I couldn't use my Adafruit ISP programmer.
These videos helped a lot: Connecting to the USBASP and Compiling and uploading
Compile with avr-gcc:
avr-gcc blink.c -mmcu=attiny10 -DF_CPU=1000000L -Os -o blink.bin
Upload with avrdude:
avrdude -c usbasp -p t10 -U flash:w:blink.bin
This code showed me how to enable the PWM.

Programming ATtiny10 with HVSP (High Voltage Serial Programming)
I've been working on a project that expanded to use all four pins of the ATtiny10. One of the pins is the reset (RST) pin which can only be used as a (weak) GPIO if you program using 12vdc. Here are my notes trying to figure that out.

- AVR high-voltage serial programming for ATtiny Github project, seems like a good simple reference
- How to use the Atmel ATTINY10 Microcontroller YouTube video showing a good way of making a CONVERTOR for an existing TPI programmer (I think), will probably design something based off this because the USPASP works great and it looks like all I need to do is put +12v on the RST pin and program as normal. I was hoping to just hobble something together (and I still might), but it would be a good project to design and throw up on eBay too (I would have spent $15 on a convertor board!).
