Betr: [smartsockets] Re: 2 tube clock with PIC16F88
- Hello Chris,
Yes, I've noticed that the connections from the PIC to the tubes are different.
That's why two programs are needed, obviuosly. (And version 1 and 2)
It should be fairly simple to change the program to suit my "choice" of connections.
If I've seen it right, it's just one table.
I have some programming experience.
Long ago, I started with the 8080 processor.
Later also the 8085. But mainly I used the 6502 in both an Elektor (Junior)
computer and of course in the Atari XL.
I've done some more programming on 8052 and 80C552. Also the 8052AH-Basic
But I was never very good at the software.
I've also build and modifies a Propellor-Clock. (Henk Soubry)
This one uses an PIC. But I only changed the codes for the remote controll.
I can read and mostly understand the code.
Also, I have a PIC-starter kit. So it should be possible to do some programming.
(I like designing and building PCB's much more)

I haven't been getting the time to do what I need to do either !
