LowSpeed CLIP NI 5761
Hello flote,
To configure a FlexRIO adapter you need to add the FlexRIO board in a LV project, then expand the FlexRIO, right-click on the adapter module and select the Property option in the menu.
Inside the property window you can select the Module you are using and the CLIP you want to use.
It is not necessary to use SPI lines to configure the sample Clock. There are specific inputs in the module to configure it. To know how to use these options, open the example embedded in LabVIEW “NI 5761 - Clock Select.lvproj”
Hi flote,
I believe the documentation you are looking for can be found in LabVIEW Help by searching for "5761" and selecting "NI-5761 Low Speed CLIP." This help document gives most of information needed to enable the Low Speed CLIP.
The main parts to take away are:
- An external clock must be provided and set as the Sample Clock
- See the Sample Clock Select CLIP signal name and the options you have ( 2 = External Sample clock through CLK IN and 4 = External Sample Clock through IoModSyncClock)
- And you will also need to ENABLE the Low Speed Mode
To do this, let's open the NI 5761 - Clock Select.lvlproj example. You can find this by going into LabVIEW and clicking Help»Find Examples and searching for "5761." Next, examine the project and notice there is a Clock Select Host vi and a Clock Select FPGA vi. Let's start by expanding the RIO Device you are using. You will then see the CLIP it is defaulted to below, let's right click this and select Properties, as shown below.
From the next menu we will select the device to use the Low Speed CLIP!
Now that we have the proper CLIP selected, we will need to set the Sample Clock. To do this, open up the FPGA vi and notice the Front Panel has a selection for Sample Clock. We want to set this to one of the two allowable values from the Help. I have selected to use CLK_IN or "2".
After we have selected where our slower clock rate is coming from we need to adjust the vi to fix the Analog Inputs. Since the Low Speed CLIP is a single sample CLIP we need to change the block diagram to reflect this.
Notice the broken wires illustrated below:
So since this is single sample, we won't need the multiple inputs, or the entire case structure really.
Now that we have configured our input there is only one more thing that we really need to do which is to Enable the Low Speed Mode. Refer back to the project explorer under the CLIP we have selected. Here you will find the bottom selection is to Enable The Low Speed Mode.
We need to drag this item onto our block diagram and use it to tell the Target that we are indeed in Low Speed Mode.
This should be everything you need to get your 5761R up in running in the Low Speed Mode. Please let me know if you have any further questions or if anything was unclear!
Regards,
Kyle S
