Is IAP the only way of storing persistent data?

Hi

Im using the LPC2103 MCU and I need to store some calibration data in the flash, so the calibration doesnt get lost when the system is powered off.

I know I can use IAP to do this, but is there other mehods?
Not that I dont like the IAP solution, but just to know.! :-)

I guess I have to reserve some of the flash for this purpose. How is that done in KEIL?

  • Good catch. I don't think it is the same post (I think I picked up my info on the nxp or standardics forums) but the gist of the information is the same as I read.

    I might be wrong when I thought they claimed max 13 writes before erasing and rewriting the sector. This post claims 16 writes.

    Anyway - this is a link to keep. The information in it is very important and should have been in the procesor manuals. (Or maybe it is, for some LPC chips, but I haven't found it in the manuals I have read.)
