Tutorial: Convert a Digispark in to a LittleWire AVR/PIC programmer and IO multitool, or ttl serial

<< < (2/4) > >>

dmcinnes:

Finished the ATtiny85 programmer using a chip socket and the Digispark proto board.
Loosened up the socket by sticking some headers in there. Now the chip goes in and comes out without having to force it.
Added an LED on P4 to show when it's being written to:




Ugly underside but it works  :P

@dmcinnes

I'm glad that you found the LittleWire app useful. Have fun!

Also you are right, the pin numbers i refer on the website aren't the actual Attiny85 pin numbers. I gave the numbers in the order they appear in the 6 pin AVR-ISP connector. You found solution in the end anyway but i just wanted to clarify again :)

@Jenna

Thanks again for great tutorial :)

ihsan.

Once you have successfully uploaded the LittleWire firmware on a DigiSpark, is there any way to upload the original DigiSpark firmware back using the USB port ?


Thanks.

Bluebie:
The LittleWire firmware does not replace the digispark software - it is a program uploaded in the same way as an arduino sketch. You can replace it with an arduino sketch using the normal upload process.

Thanks for the video! I just followed the video and successfully installed the .hex to a digispark. I haven't had a chance to play with it yet, but I will soon.
