Why does DATA or EEPROM not work 18f2450 ?

[Bruce]

The easy route would just be to use the 2455, but you could use ERASECODE, WRITECODE and READCODE.

This memory wears out a lot faster than EEPROM, and you have to erase before writes, and deal with different block sizes, etc, but it's do-able.

Melanie posted a nice tutorial here somewhere on this.

I will have a go with the writecode / readcode and see how that goes....

Thanks for your help :-)

Thanks Dave & Bruce

I tried with no success to use the write / readcode, so I ordered some 18f13k50's today and while I was at it I realised my dev board (easypic 3) would not program em, so I splashed out on a pickit3 programmer too lol, new toys to play with! yey

I'ts going to be oh so easy with these new pic's and me shiney new programer, right....?

I'm surprised the EasyPic 3 can't program theses... I would try to download the latest MikroProg Suite from MikroElektronika website and see what happen.

More toys never hurt, that's for sure, and now you can also program them directly in circuit without nasty adapters

Hmm, acording to the pickit3 bumf, it now can program all pics, unless I have read the description wrong (again).

It has to work. PICKIT 3 is their new beloved toy. I still like my PICKIT 2, but they've stopped the support. However, it seems that some third party/clone site provide some extended support. It is not that hard to add new device to PICKIT 2, but hey, PICKIT 3 is so cheap (when you compare to other 3rd party one).

Not sure how good/complete their standalone application is VS PICKIT 2 though. Would be nice if they would open their source... but I guess it will never happen since they've lost a load of sale with PICKIT 2 with the tons of clones...
