PSoC 5, 3 & 1 MCU

[user_3907121]

Hello ,

We are using CY8CPLC20 controller for power line communication (PSOC1) . "FSK modem only " is selected .Example code given in the datasheet is flashed on both the kits. In the receive end before receiving the data  some  garbage values are received. suppose i send (AB, 01,10,23,88..) , at the receive end i get values like (FF,FF,FF,FF,AB,FF,FE,FF,FF,FF,FF,FF,10,FF,FF......). Do i need to append overheads to the transmit message?

Regards,

Hello Divya,

You will have to use the same Network Packet structure, as shown in the datasheet of PLT User Module.

Hi Sampath,

1]can you tell which page no. of PLT user module you are suggesting?

2] Even if you don't send anything(disconnect one controller) ,we are receiving some garbage values( FF ,FB ...)

why is it so?

3] can you provide any detailed document for implementing PLT using FSK modem only.?

Regards,

Divya K

Hello Divya,

1) Kindly refer to page 8 and page 9 of PLT v 1.50 datasheet.

2) The powerline used for communication may be noisy.

The receiver gain may be too high

Noise level threshold may be low

3) You can kindly refer to PLT v 1.50 datasheet. The Sample codes are in pages 41 and 42. Unfortunately, we do not have a seperate document for Modem Only.

Best regards,

Sampath
