Thanks for suggestions...
for use by the teacher after kids brick a chip, or for use by the kids themselves?
Both. The students brick a lot of UNOs and NANOs ... basic atmega328p
but the SMD versions (which are cheaper and more used) are far more tricky
due to the QFP package.
Solutions should be simple to be handle by absolute newbies..
They need to unbrick when totally screwed fuses prevent them to use
ICSP or other things like other UNOs in breadboard ISPs for DIPs
Solutions involving mounting circuits and bread boarding are not suitable.
First I thought I would find "professional" programmers like RT809
complete with all JIGs could do that using a QFP ZIF adapter..
But I got really confused **IF* the programmer supports these specific
HVPP demands.. TL866II has advantages by having MiniPro under any LINUX..
But so forth i could not determine if the support for bricked ATmegas should work
and what type of adapter should be used..
That AVRRESCUE is great for DIPs but again QFP packages are damn common
.. the students damage UNOs and NANOs primarily by:
- dead shorted regulators..
- totally wacko FUSE bits.. impossible to say just clock or also ICSP.
- dead ATmega.. being each day harder to order .. and very expensive in small qts.
Basically I got curious as well how hard could be to find a JIG to HVPP or HVSP
ATmegas using regular professional like programmers..
Got surprised by the lack of ready made solutions.. like adapters w/boosters
and sockets...
Any suggestions still very welcome even to satisfy my own curiosity
Thankx
