Hi LEDDave,
16F628A might be easier to drive 7 segment as no driver translator chip required ( because it has enough ports ). Your biggest challange will be due to 31 lines of code limitation, in the Demo program.
I do not know if assembly code is counted in that limitation.
If you have that problem I am sure Mackrackit and I would compile a few programs for you, enough so you believe this compiler is worth it's price.
If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

Yup, I will help.Originally Posted by Joe S.
Problem is, I can not find a "large" PIC that will work with the demo and the PICkit1. (14 pins)
So LEDDave may have to get a 16F676 and one of us build the hex for that...

I know nothing about the PICKit1, can you use ICSP with it ?
OK I just looked at AN258 http://www.microchip.com/stellent/id...pnote=en012103
and it clearly shows PICKit1 using ICSP so he can go OFF BOARD with some jumper wires and program chips.
So is it that the PICKit1 firmware does not support bigger chips ?
This will work, until he get's serious. http://cgi.ebay.com/Microchip-PIC-JD...item1e595bbf81
Probably Won't do 18Fs but will do nearly all 16F & 12F series.

An adapter can be made for the socket, but the PICs supported are limited.

Feeling rather pleased with myself this afternoon.
I looked at the diode array diagram in my PICkit1 and the program mackrackit had written for me to run D0 - D1 - D2 in sequence and thought I'd like to add D3. So after much head scratching (believe me) I can up with this:
ANSEL = %00000000
CMCON0 = %00000111
START:
'D0 HIGH
TRISIO = %11001111
GPIO = %00010000
PAUSE 500
'D1 HIGH
TRISIO = %11001111
GPIO = %00100000
PAUSE 500
'D2 HIGH
TRISIO = %11101011
GPIO = %00010000
PAUSE 500
'D3 HIGH
TRISIO = %11101011
GPIO = %00000100
PAUSE 500
GOTO START
The D3 bits mine:-) So I compiled it, no errors and whoosh: D0-D1-D2-D3 chugging along in a nice line and not a hint of burning smoke anywhere.
I know it's only a small step, but still really pleased. I'm going to read and try to fully understand the GPIO / TRISIO port register relationship over the weekend. Still much to learn but Rome wasn't built and all that....!

COOL!!!!
Progress...
About future programmers.. I would recommend the PicKit2 over anything else. It is a bit more expensive but worth it.

In my shop I have a PicKit1, PicStart+, and two PicKit2's. Guess the ones that get used the most..
I will sometimes build a JDM type circuit into a project if it is something the customer may have to update and they work OK and I have a board I make for kids to learn the basics on so they do have their place but...
Just my opinion... not trying to start a programmer war.

I do like the PICKit with it's USB connection, early days but I think I'll stick with them for sure.
I've a lot of basics to learn in the meantime, any thoughts on how I should structure my learning?
I'd like to learn how to program the 12F683 to output a binary pattern (xxxx-bin) when a button gets pressed.
Another thing I'm wondering, does the basic principles of one PIC transfer to others (I'm guessing yes, why re-invent the wheel every time) so learning the 683 chip would be a good place to start for a knowledge base.
Question after question from me at the moment, I do apologize for that.
Interesting stuff these PIC's, I can't wait to get a reasonable working knowledge.

Ha, no war, I paid 8 bucks for my first JDM, that's why I bought it. It works, but I prefer MY PICKit2 over it. I think as cheap as they are it is worthwhile to have as a backup.
