Cant get my PIC running

[mackrackit]

Another assume i made is that if i upload a longer program to the chip and then a shorter one, part of the longer program still remains in the memory but this is not issue since the new shorter code has its end coded or a infinite loop at the end. Is this rigth?

I assumed this becouse there are no option to empty the memory in the program.

I am not sure if it will cause a problem, but I think it will if the chip is not erased.

In MPLAB on the toolbar, configure, settingins, and the the Program Loading tab. Clear everything.

Oh, but there is only one problem: My programmer is not a standard model and mplab doesnt support it :/ , so im unfortunately not able to do it that way

OOPS, I thought you were using MPLAB.
Now I read closer and see the link you provided. The link does not work.

A hex from a blank chip will have FFFFFFF not 0000000 as you example.

And you might try ICPROG for the program to load the chip. It might work with your programmer (it works with several)and I think it has an erase feature.

Strange, it works for me :S

When i read the chip, i will get 00000 not FFFFF, there is possibility that programmer or program converts the bits? sounds wierd, are you sure about this? And after writing program and reading I will get hex like this:

as i earlier said. the remaining space is filled with zeros like those in the last lines above, is this normal? Should those zeros be F's too?


ICPROG unfortunately doesnt work with my programmer, however i found out that writing a new code to the chip "automaticly" erases the old one, so that should not be problem then.
