====Atmel ICE====

This device is used to program various Atmel designed processors.
It has one serious fault, in that the sockets are wired back
to front but otherwise it works well. The dumb wiring is the
main reason for this page. I got it working fine once and now
forget how it's broken so need to rediscover the stupidity
yet again.
I got the PCBA version of this device in 2019 for £47, they now
cost £90 in 2022. Microchip outpace inflation like nobody else.

The key in the port is on the wrong side so you
can either plug the cable in back to front (not
recommend) or cut the notch off your cable and
turn it around and plug it the right way around
at the other end (recommended but I don't
accept liability for any error). Maybe Atmel
(now MCHP) should just employ competent engineers.
PS. MCHP will sell you mis-wired cables so you do not
need to do the above, but having mis-wired cables in your
collection may be even worse.

Both sockets contain the same signals just wired to
different pins.
