Function Documentation

void random_init

(

unsigned short

seed

)

Seed the cc253x random number generator.

Parameters:

seed	Ignored. It's here because the function prototype is in core.

We form a seed for the RNG by sampling IF_ADC as discussed in the user guide. Seeding with this method should not be done during normal radio operation. Thus, use this function before initialising the network.

unsigned short random_rand

(

void

)

Generates a new random number using the cc253x RNG.

Returns:

The random number.

Examples:

example-broadcast.c, example-collect.c, and example-multihop.c.
