Random number seed

[kwelna]

Actually the if statements work fine, but I like adding the "Else" statements and "EndIf"s to clean up the code (Thank you Sazer). and comments to clarify the logic behind my code. My real issue is the way the code is now, my code always provides the same sequence of numbers on start up. I need it to be different each time at startup as well as any other time it basically is supposed to randomly flash 1 of 5 different LEDs - 5 times and then stop and wait for B.7 to go high and then star again. So how can I randomly add a seed to the very first iteration of this process. I read some where that you can pull a value from TMRO, so it will give you an initial seed of 0 to 255. Any thoughts?

Hi, Kwelna

Just keep the last value before switching off in EEPROM ... as a new seed !!!

Duh!!! So simple I never would have thought of it.........well maybe in a week or two.... I am alwqys looking for a more complicated method. that is what happens when you get old!

Thanks again

that is what happens when you get old!

Imagine when you'll be as old as i am

You could still use an hardware solution... count pulses at the output of a white (even pink) noise generator... now it's going to be really random. Always a long debate around this....

Hi, Steve

You were talking about the MM 5837 ... I suppose ???

The only one corresponding to your age LOL !!!

LMAO! well could also be a simple op-amp (maybe dual), cmos gate etc etc. no need for a dedicated IC. Maybe PBP SOUND could do the job.
