Hi All,
I am student and not able to go ahead in my project because of the
following requirement.

I have to store 250 bytes of data in a flash memory of 512 KB
(MC9S12DP512), abt 10 times a day. I read that we can read/write even 512
bytes of data in Flash. I have tried by following the instructions in
freescale document. I am not able to write and totally confused now.

Can you please tell or give me an example on how to partially read and
write the flash ?

Thanks for ur time !

Start a _new_ thread (not replying to another mail) with
_appropriate_ topic.

But even then, I'm afraid your question can't be answered.

IOW "please do my homework".

Erasing a flash block and writing to it is described very clearly in
the manual. Ask more specific.

This group descends into chaos.

I know that one, although it says go forth and multiply, you should code it as repeated additions in Cobol.

OTOH, I can't find any instruction to convert 240 Mains into 5V DC, ideas?

Cheers,

Theo
