Well I've been at it since 8:00 am, Fnarr! Fnarr!
Anyway just to keep everyone informed.....
The full on "cased prototype" has now gone past the breadboard version with:
All low power ports fully setup, wired and working.
All camera ports fully setup, wired and working.
Buzzer wired in and working.
RTC wired in and working.
Separate board for HP section built and populated (just needs wiring).
I/O port wired up for beam breaker circuit board.
All LED are state changeable by the software.
IR receiver fitted.
Board keepers fitted.
Now everything works from 5V USB so no need for external PSU.
Addition of 3.5mm sockets on rear as low power ports.
Then tonight in software land...
Re-written menu routine.
Added section into the setup menu allowing all IO functions to be tested.
Might finish the hardware tomorrow so long as nothing changes......
Still have the HP board to wire up.
IR output section to build.
Oh and a box with all the ports normally on a camera, flash etc to test the device.
Then I can start on the trigger leads
