Hello Birapxi,
I am not to familiar with creating a custom board, but I will look into this for you and let you know what I find out.

Hi,
Does anyone have a PCB example for NI cRIO-9951?
for Altium, Cadence, Ultiboard... Any PCB software, it doesnt matter 🙂
Precisely, I am using Altium Designer to design the schematic and PCB,
and I was hoping to find on the CD Kit 1.5 an example... But nothing.
Mainly, the interest is to place correctly the connectors inside the module space:
Thanks in advance

Please reference the following link for support on the NI-9951 module.

Hi!
The scenario:
I'm currently working on a custom CompactRIO Module. The hardware is mostly done, I've installed CompactRIO MDK 1.0 and I'd like to configure my CompactRIO system and develop the driver VI for my module.
The steps needed for configuring the cRIO System before begining developing the driver VI are the following (as written in the MDK documentation):
1. Launch LabView and select FPGA device as execution target. The Embedded Project Manager window appears.
2. Select File-> New and create a LabView Embedded Project (LEP) file.
3. ...
Used equipment:
- LabView 2011
- LabView FPGA and RealTime modules
- NIRIO 4.0
- NI-CRIO9024 Controller with 8-slot Chassis
- CompactRIO MDK 1.0
The problem:
After launching LabView and selecting FPGA as a target (see attached figure), even when hitting the 'Go' button next to the slide-down menu the Embedded Project Manager window won't appear.
I also tried searching for it in other menus, with no luck.
Questions:
1. Where can I find the Embedded Project Manager?
2. Is it possible, that I can't find the Embedded Project Manager window because I have an old version MDK (December 2004 is written on the manual)?
3. How can I create an LEP file in that case?
4. Can I use (and if yes, how?) the 'Create instrument driver project' option? (see attached figure)
Waiting for replies,
Levi

This is an update to my problem.
I couldn't find the Embedded Project Manager, but I've managed to do the following steps:
1. I've selected FPGA as execution target, created an FPGA project.
2. LabView was able to detect the Chassis and a 9401 module plugged into it.
3. I've right-clicked the chassis, selected Add Target and Devices (see attached figure).
4. The Add Target and Devices on Chassis window appeared. I've selcted New Target or Device.
5. The New C Series Module window appeared.
This was a similar window as in my MDK (an old version MDK), but I couldn't select "generic" as Module Type.
Any suggestions on my problem?
Thanks,
Levi

Hi!
After some research I managed to create the connection between my custom cRIO module and LabView.
The complete solution (with LabView 2011):
- add line 'cRIO_FavoriteBrand=generic' to the LabView.INI file
- launch LabView
- creating an empty project and select FPGA as execution target, click GO
- select 'CompactRIO Reconfigurable Embedded System' as project type, click next
- the next step is the detection of the chassis/ modules, followed by the creation of the new FPGA project
- adding the custom module: right-click on FPGA Target -> New -> C Series Modules -> New Target or Device -> C series Module -> OK
- Enter name, select as module type 'generic', enter location
Hope it will help someone someday.

When you change the value of the Pin, its interact directly with the electrical pin. so when developping a new card, do not forget to add electrical protection to your board... Damaging a back plane or a FPGA cost a lot ;-).

Hi!
I'm developing the driver for my custom cRIO module. The module has 4 analog input channels.
After analog-to-digital conversion I need to transmit the digital data via the cRIO bus.
I placed an FPGA I/O node on my block diagram (see the attached image), but I can only read if the pin's state is HIGH or LOW, not the value of the ADC.
How can read the value of the conversion?
Thanks for the help,
Levi

It's impossible to help you on this without the comprete electrical diagram. The convertion is it continuous or trigerred? do you have a buffer on your custom board? do you have a PLD? only a trigger pin on your diagram mean nothing... you may need a loop with a clock... I mean You show nothing actually.
