Hi Patrick,

it is possible to store data while running from the internal RAM but
it is not possible to run a program from Flash while programming
another part of the Flash.

The Keil C-Compiler is a good choice but it is not freeware. There is
a version that allows you to write 16k of your code and can be
downloaded from www.keil.com

Size of Blinky, a few hundred bytes, unless you use such a library
function like printf, then we are immediately talking a couple kbytes.

There is a free compiler (GNU) and if you take ten minutes to search
this forum you will find many references to that compiler as well. One
warning, the library functions of the GNU are very big and increase
the size of a program a lot compared to a compilers you have to buy.
For the application you mention (sounds like a data logger), the GNU
compiler is perfect, actually the 16k of the Keil compiler might be
enough to do the function you mentioned. 

Bob
