 Hi, I'm an electronic engineering student from Università dell'Aquila Italy and I'm doing a thesis on powerline communication. I have some problems with CY8CPLC10, 2 devices do not communicate on a real network with distances greater than 10 meters but the two devices communicate on the same socket. The transformer I used is the Murata 78250C because it was the only transformer that has the university

I program the CY8CPLC10 with I2C using the ATmega328 microcontroller.

   

Thanks.

You have seen this application note ?

And scoped line to see what the noise environment looks like ?

Another thought is to place fixed tone on line thru your board

   

interface so that you can look at line with scope and/or spectrum

   

analyzer to see what signal path looks like.

   

 

   

Be very careful about scope probing and grounds to make sure

   

you do not violate scope/analyzer input constraints. Maybe consider

   

using scope differentially, eg. one channel/probe becomes reference,

   

another channel/probe becomes signal probe. At minimum consult scope/

   

analyzer manual for peak AC and DC input constraints.

   

 

   

Use one hand/arm measurement techniques when you proble HV circuits.

Hi, I`m a newbie for bolth Arduino programming and interfacing with the CY8CPLC10 through I2C but, I have two CY3273 (low voltage evaluation boards) and I would like to use them in an applciation.

   

First of all I tested the functionality of the boards with the I2C > USB board they provide, I`ve connected them to my PC, and I can send/receive hex messages.

   

Now I would like to connect one of the boards to the PC, and send data to the other board/node and read the data with the Arduino UNO I2C interface. I`ve read the Application nodes for Designing an external host, I understood it, but beacause of my lack of knowledge in this area I would need some help. Maybe an example of simple reading the data sent from my PC, to the node connected to the Arduino through I2C.

   

Could you please get me started?

   

 

   

Thanks in advance!

There is example code in each components datasheet, towards bottom

   

of datasheet. Start there. I would first tackle board to board com, then

   

the PC side. Something simple like transfer a byte from one board to

   

another.

   

 

   

Youtube and vendor websites, like Phillips (I2C inventor, now NXP) I

   

would imagine have tutorials, videos.

   

 

   

Regards, Dana.

Thank you very much for the reply Dana! I`ll try to figure it out somehow, with the tools you mentioned.
