Random numbers same each time. Seed?

[stylo]

Hi,

I'm trying to generate a random number on a button press. 1 - 10.

In FC7, I'm just using a C snippet containing "Ran1 = random () % 10 + 1"

This works fine in software, but the moment I burn it to the chip (using a "12F1840"). I get the same sequence of random numbers every time.

I'm asuming this is because the seed being used is the same each time, but for the life of me I cant find out how to change the seed.

Any help would be much appreciated.

Thanks.

You could use

Code: Select all

srand(seed);

in a C block.

Use a timer or a counter to get a 'random' seed.
