are there like. no good solutions for viewing logic analyser dumps on macOS? Both pulseview and GTKWave don't seem to run under modern macOS...
i guess i can just use my linux machine, but ugh
next question is how do i actually physically interface with these pins. can’t use clips because well, it’s a flat surface, and the spacing is kinda weird so any prebuilt pogo pin things are ruled out
Ok, have a pinout of sorts
Ground Data Data Data Data Clock Half-press 1 Half-press 2 Shutter fired 1 Shutter fired 2 Bat+ Logic voltage
now we check if there are any common data interfaces with 4 data lines of some description and a clock
Is this just fucking SPI with a bonus pin
it would really help if I could non-destructively open up one of the program cards but they are sealed shut completely
i think it looks like a clock at least
in case you are wondering how i got this. i am just holding a pogo pin on the connector by hand
wtf is this though
its clock. but not.
jokes aside. there's two data lines (in/out i guess), one clock, one fucked up clock, and whatever this is
New working pinout:
Ground Fucked up clock Data Data Mystery pin Clock Half-press 1 Half-press 2 Shutter fired 1 Shutter fired 2 Bat+ Logic voltage
If I could make a guess, the mystery pin is probably a chip select
I think I need to come up with a proper test jig, I can't get a consistent reading just holding it on the pins by hand
lmao i killed the camera. rip
@protosphere how even
@whitequark i have no idea, it just doesn't turn on anymore. i guess the battery could be dead, i'll have to test
@whitequark hm no, it's actually getting power (5.8v instead of 5.9v, but I imagine that's still enough. Logic power level is like 2.8v though instead of ~3.2v)
@whitequark pretty sure I somehow killed the processor
@protosphere sounds somewhat unlikely unless you shorted one of the logic pins to VBAT. do you know what's inside? do you have an oscilloscope? how expensive was the camera?
@whitequark it was €30. I have no idea about internals, and the service manual is pretty useless in that respect. No oscilloscope.
@whitequark I'll get another battery but they're like. half the price of the camera because it's a 2CR5.
@whitequark I just took out and reinserted the battery and it's alive again. bit weird but ok

@protosphere yeah this just happens sometimes when poking at devices

  • don't panic
  • power cycle everything
  • keep your head calm

is the best advice for this situation
