Random
This section refers to the following sample application(s):
02-random
The
LTC5800
features a random number generator device which samples the thermal noise of an internal circuit to generate a sequence of random bytes.You can not use this device after having issued the join or search commands to the mote. Doing so will result in the API returning the DN_ERR_STATE error code. This device can not be used if the mote is configured to join automatically.
The 02-random Sample Application
The 02-random sample application creates a task which periodically reads 16 bytes from the random number generator device. It prints those bytes on the CLI, in hexadecimal format, as shown below:
