Yes you can change fuse settings using the TL866. Moreover, you don't have to worry about cocking them up like you do with ISP programming (e.g. reprogramming the RESET pin as an IO), because pulling the AVR and putting it in the ZIF socket means it will be parallel programmed.
Thanks - I will give it a try.
- What is the definition/significance of parallel programmed? Thx
Update: tried, but didn't get very far.
In the MiniPro software you can search by Hex and ASCII. Problem is - I don't know what I'm searching for (fuse, Fuse, use, etc. don't seem to get any hits in ASCII).
Upon further (keen
) observation of the MiniPro software I noticed that it has a section called IC Config Information which says:
Fuse Low Byte: 0xDE
Fuse high Byte: 0xDE
Extended Fuse Byte: 0xFD
Lock Bit Byte: 0xCF
What I think I'm looking for is the fuse setting for Pin 14 on the Atmega 328P, and then how to toggle it from what I think is currently off to on. Any thoughts? Thx
PS, any chance there is a way to get the MiniPro help file to display in English?
Update: Oh boy!! Turns out there is a tab called Config hiding next to / behind a couple other tabs called Code Memo and Data Memo. In there is Fuse City! Now I just need to figure out which of the checkboxes is the right one for Pin 14 (which theoretically is going to allow me to probe for frequency). Any suggestions on which one toggles 14? And any safety tips on how to avoid bricking things? Thx
Update: found this:

•Bit-6 : CKOUT : When set clock pulses are output on PB0 (Pin 14)
Looks like it's time to give a Go!
Will report back shortly as to whether the Atmega is still happy....
