I hate to ask the obvious, but Im running out of avenues…
I have recently changed the version of MMjoy that I was using as part of fault finding my DIY pedals build, as recommended by many helpful souls.
I did this and updated the firmware on that (pedals) Pro Micro card, and then had to update the firmware on my other devices.
- ka50 (hybrid) switch panel
- cyclic controller, which is an old TM F22 pro being repurposed (at this point just the buttons on the grip, no axis yet) to replace the standard grip on the fllight link G stick
I have all the sets save to text files for the ka50 and cyclic.
however they seem to be completely useless now. ( I assumed the shift register pins would also be saved)
the ka50 I have managed to recover and manually configured.
but the cyclic using the TM shift register with the 4021 shipset, just will NOT play ball
Note: there was NO physical tinkering here, everything was in place and working, only change was the firmware upgrade…
(and just llike that, my [ka50] flying days are over) the one time i didnt grab a screenshot of all the settings…
I’ve tried every combination i can think of (1 at a time then test);
setting chip to 4021, I’ve tried setting the chip count from 1-6,
I’ve tried all those combinations with CS set to B1 and B2 (which is the CLK)
all with MISO set to B3(edited)
Even changing the VID, PID hasn’t had any effect
nothing gives me any button interface…
both devices are wired identically
cab be seen clearer here
74HC165 chipset shift register
(Thrustmaster FLCS/F22) 40121 chipset shift register
NOTE: before anyone gets bent out of shape, the cheap chinese shift register is labelled in the diagram as per the PCB (so i didnt screw it up again) which is marked incorrectly, much time and effort mapping out the pins with a mulitmeter (with the gracious assistance of v81) to verify and confirm the actual pins on the chip to the pins on the plug.
to riterate, nothing physical changed, no wiring, no connections, purely a firmware update
I’e got a sneaking suspicion that the latest firmware has broken the 4021 chip set shift register
