Code Examples
When placing the PLT User Module, a window pops up, showing three options (see
).
a. “FSK Modem”
With this choice only the FSK Modem is implemented. The user can implement a custom net-
working protocol to manage the communication over the powerline.
b. “FSK Modem + Network Stack”
With this option the FSK modem and a proprietary network protocol layer is implemented. The
user needs to create a custom application that uses the provided protocol to communicate over
the powerline.
c. “FSK Modem + Network Stack + I
2
C Bridge”
With this option, the FSK modem a proprietary network protocol layer and an I2C bridge is
implemented. There are no APIs to communicate with the network layer; instead the system will
receive commands from the external I2C host. For detailed steps on how to implement this, see
I

C Interface for CY8CPLC20.
Select the “FSK Modem + Network Stack” option. With this option FSK modem and the
proprietary Cypress network protocol is implemented. This allows the user to focus on your
custom application, while the network protocol manages the CSMA, transmission, reception and
error detection. For details regarding the other two options refer to the
