Generate a random number between 0 and X

[aratti]

I know i could get to the correct value using the following equation
Rnd1 = (Rnd0.byte0 / 255) * lim

That one wont work though because it will be rounded to 0 or 1 when dividing.

Tray to multiply first.

Rnd1 = (Rnd0.byte0 * lim)/ 255 [which is the same as Rnd1 = (Rnd0 */ lim)]

Ahh, I think i understand how */ is working now. Ive tried both ways and they seem to be working for a few seconds then my LED freezes but i think thats to do with something else. Thanks for your help

Ive figured why the LED freezes now. After generating the random number i was using */ and storing the result back in the same variable. It looks like the RANDOM command uses whats already in the variable as a seed and as i was modifying the value to really low numbers, eventually it was hitting 0 and staying there. I added a second variable and its all working now
