Bootloaders suck!

 Bigger Bigger  Smaller Smaller  Reset Reset


I just wanted to let you guys know that since the latest firmware these tiny little scopes also support frequency analysis!

I've updates mine and it works quite well. If you should have one as well, go and get the update. For updating the scope, you'll need an USB to TTL serial adapter, a few wires to remap the pins and a windows machine it seems. I haven't found a linux/mac version of the uploader (avrudb) that talks to the onboard bootloader.

If you want to flash a new bootloader as well (not strictly necessary), be aware that the 10pin header is not a standard ICSP layout.

Here's a video of the FFT feature:

Here's a photo of mine showing the pinout of the headers:

• Upload doesn't work? Do a loop-back test.
• There's absolutely NO excuse for not having an ISP!
• Your AVR needs a brain surgery? Use the online FUSE calculator.
My projects: RGB LED matrix, RGB LED ring, various ATtiny gadgets...
• Microsoft is not the answer. It is the question, and the answer is NO!
