A simple TSCH+RPL example is included under `examples/ipv6/rpl-tsch`.
To use TSCH, first make sure your platform supports it.
Currently, `jn516x`, `sky`, `z1`, `cc2538dk`, `zoul` and `srf06-cc26xx` are the supported platforms.

## Porting TSCH to a new platform
Porting TSCH to a new platform requires a few new features in the radio driver, a number of timing-related configuration paramters.
The easiest is probably to start from one of the existing port: `jn516x`, `sky`, `z1`, `cc2538dk`, `zoul`, `srf06-cc26xx`.
