VNet features

[kalim007]

Hello,
I was trying to implement "VNet" features using training video (no. 27). At first we need to execute "Flowserver.exe" file. The video was for flowcode V4, I have V5 in my pc. I could not find that file (i.e. flowserver.exe) in any folder. I tried to simulate without executing exe file, that did not work. When I tried to create VNet server, I found error message. Can anyone help me?

Hi in v5 the flowserver exe is located here:

C:\Program Files (x86)\Flowcode\v5\Tools\Vnet Server (64bit OS)

C:\Program Files\Flowcode\v5\Tools\Vnet Server (32bit OS)

Thanks!! I found it.

Hello,
I have used VNET video tutorial from this website. I completed the tutorial and came up with few questions. First, when I send '0' from buffer, I see 85 in receiver side (as you seen in tutorial). When I send either '1' or '2' ;I see '9' on receiver side. I do not understand why?

Second, I could be wrong but my feeling is that I can add more than two microcontroller using VNET features. Is this correct? I am planning to test this features in breadboard. Please help me if you can.

Hi,
I have run 5 CAN modules at once, across two PC's on a LAN..

Hi Pete,
Thank you for your post. I understand that one can run many CAN module in one network. I am using PIC16F877A microcontroller. I looked at data sheet and could not find CAN features over there. So, should I assume that CAN is different module that I have to acquire separately for my circuit?

Since I see that I can add CAN features from flowcode even though my microcontroller does not have it. I am planning to build a three-microcontroller network circuit using PIC16F877A in a breadboard. Is it possible? Am I missing anything here?

Hi,

This micro does not have any can features on board, however you can do it by using an e-block, click on the link and it will take you to the data sheet...

When build in your chart you just need to add the CAN module to your panel and the macro flow icon will have all of the commands you need to build your CAN project.

I also suggest that you go to the examples on the MM website as it has CAN examples for you to use and learn from.

I think they are here, can't tell as I am responding to you on an iPad so I can't check the contents of the zip file easily, I know it's around here so you may have to explore a little...http://www.matrixmultimedia.com/lc_index.php?p=18

I had 5 CAN units running on VNET using your select micro... 5 instances of course!

Let me know how you go..

All the best

Pete,
Thank you for your response. I do not have CAN module with me. So, I have to wait until I get it. Or I will find other microcontroller where CAN module is available.

Hi,
There are a number of chips with CAN on board. Checkout the Microchip website selector

.remember that you will need an external CAN chip to interface the Micro to the CAN network bus...check out the data sheet on the MM site...EB018 eblock..

You will see two chips on the board, one is the CAN chip, the other is the CAN line driver...the line driver and associated components are what you need..

I would recommend a couple of EB018 eblocks to start with until you get confident that you can build your own
