Hi Everyone!

I am considering to use the Random number generator (RNG).

Please give the information to genarate the Random number>

You can use LFSR as it is one of the less time consuming method. It will generate pseudorandom number though.If you are using RTC in your application you can use this time as seed. Or may be two independent time source in your controller to get a seed value.

Hi mc-san!

Thanks your quick response.

The pseudorandom number is OK for my application.
I am considering to genarate the White Noise.

If possible, please show me code of LPCpresso.

Hi Mc-san!

Thanks your kind and clear imformation.

You refer to the stripes of the introduced document, and create a code.
Probably, I think that the assembler of LPC1830 is used.
<---Since there was good code of C in an introduced a site, it will inprement it by C.

Thank you very much.

If possible, I want to get the random() noise(not 1 bit noise).
random noise is more than 16 bits, I think.
