The Industrial Raspberry Pi Forum

Hi community,

i'm newbie and really need your help, please.. i stuck now and don't know how to go forward...
i have a project as follow:
- I connected my revolution pi master (core, connect..) with an external board ( like xilinx zybo board ) per ethernet cable. On Zybo board i need to read all I/O data, counter data, ... of all slave revolution pi modules (DI, DO, DIO,AIO...), which connected with my master modul. So i have idea that i will write a program on Zybo board and access the process image of master per ethernet WITHOUT change anything on source code of master modul. But that means, that my Zybo is like a spy !? I don't know whether the master will give permission for an external access like that or not.
- If yes, please tell me how to do that. If no, that means i need to write some program and add this program to source code of master modul? This program will collect all I/O data and cyclically send it through ethernet gate of master to Zybo board. Can someone tell me how can i open the ethernet gate and use it for sending data please?

Thanks all in advance!

Hi,

You will need an application on the RevPi which gathers all the data and then sends it to your board. For this application you can use a variety of different languages like python, c or anything else which can deal with ioctl. For beginners I highly recommend to use Python with the library revpimodio2.

I don't know anything about the zybo board, but you probably can use mqtt or plain tcp for data exchange between these two devices.
