Hi,
I'm trying to restart my arm-embedded project.
A few years ago I had a working compiler, with some utility-files.
I made a new cross-compiler (fpc svn 31290). But I don't find where the
interrupt-numbers of an STM32F103xx processor are defined.
So I made an inc-file and added that to e.g.

I just checked, when I created my own units for other devices I included
those const's, it seems that they never were in Jeppe's files could it
be that you saw the

Comments please.
If that's a proper way to do this, how could this be included in a
next version of fpc ? Do I make a bug-report including the new file,
with diffs
Hi All,
I need to generate random numbers to be used as IV of block ciphers. My
question is: is FPC built-in PRNG good enough as comparing to /dev/urandom?
On the other hand, /dev/urandom in my impression is fairly slow, how is the
speed of Random() comparing to that?
Thanks!

​Well, practically, how can I get totally unpredictable numbers?
By using /dev
