Hi Alan

 

Thanks for coming back it was really a rhetorical outburst at yet other project failure. But in a way its nice to know I am not entirely alone.

It looks as though you have been there before me. I am relatively new to PIC programming and I don't know what I am doing. Try to "Save" from my programmer does not work it saves the text file OK but not completely. So if loaded into a new  or blank PIC it won't run. However if say down loaded from an operational PIC held in the programmer S/W and modified at HEX level then load into a blank PIC its OK!! I have a lot to learn.

 

I have a "store" of stolen routines that will run so I am trying to modify them to my applications. Several have worked OK but its too much to ask to get a good one every time I suppose. Like changing call signs and locator in ROM and altering the configuration of speed etc for a CW beacon. Straight forward keyer no memory is another and Johan's SM6LKM stuff is very good I have found. A lot of articles promise a lot but don't deliver, it would be really nice if they always attached a text file of HEX because otherwise whats the point? Its easy enough to use character recognition to down load HEX from the printed page ... it works for me. It just means you have to be very diligent checking each line of text. A ruler and strong glasses it works every time.

 

I suppose I am at the stage where I just want to build projects as advertised I don't have the knowledge to write from scratch but have managed to modify some programs.

 

This may seem a bit off topic but now we seem to be into automated Beaconing at each other on MF/LF ......"if you can't beat 'em .......... " PIC is one way to go . Saves tying a up a PC.

 

Any way its stopped raining, garden to work  to do and another lot of Bees to hive. This is not how I saw retirement.

 

Thanks for the info and encouragement.

Hi Peter my success is much higher than that BUT I have found some PICs wont
program correctly on some programmers though the s/w indicates the ought to.
I would say if you are not using a Microchip programmer and s/w this might
be part of the cause.?? This is one I have run into.

Reasons for lack of source inclusde, shyness and not wanting to be cricised
for poor or naive programming. Producing commented source is quite a labour
intensive job. If an "outsider" is to understand exactly what you have done.
Many who reuse chunks of code cant be bother with the hassle

Then I have seen code "stolen" and used for profit making ventures, or 98%
copied, without any reference to the originator. Does it matter.....well it
does to some people. The code is the majority of the investement in a PIC
project. Remember a assembly coders stock-in-trade is a large collection of
small routines which he used continually to achieve standard operations.
Because these are used more than once they are usually well tested.

I like to see source because I can learn how to write it myself from other
peoples approaches. The most exasperating thing is if you suspect a bug (not
just not working, but an exotic one)  you have no way of. helping the
originator

Success rate is about 10% on projects with the HEX code attached.

If people don't want their projects duplicated then don't publish them
FCS!!!

Its pointless!
