Without any SPI device connected to the port pins, I'm merely trying to make sure I can wiggle the SCK and MOSI pins first. Each digital line can be individually configured as input, output-high, or output-low. I didn't see that note. What can I try? Setup WiFi and Ethernet for the T7/T4/T7-Pro, Controlling LabJack T4 and T7 with 3rd party HMI or PLCs, Frequently Asked Support Questions (FASQ), Error 1722 from LabVIEW Run-Time Engine 6.0.2 Installer. Yeah I ran that program (SPI.ctl) but I meant to say that this sample code is not quite conclusive for SPI communication establishment, even if I don't connect the clock pin or CS pin to any pin on the other device, this program works. All forums are in a read-only state for archive purposes. - Fixed the U3 and U6 stream ScanFrequency for 100 to 1000 Hz so it does not use low-level settings that cause interupt overloads on the device. The LabJack's maximum SPI clock speed is about 120kHz. the problem is that I cannot acess the sample time field.I guess that it's coded in a dll file inside the VI. However, this function is NOT listed for the 3U and instead, byte 8 is listed as "Reserved". See the low-level function description in Section 5.2.15 for more information about these parameters: Following is pseudocode to do the actual SPI communication: I've used the code above for implementing an SPI interface. What would an example of using this function look like? You were right. Every LabJack is backed by our free Legendary Support, for life. The digital I/O use 3.3 volt logic and are 5 volt tolerant. Please let me know if you have such sample available. Top. Thanks for replying back. So far so good. For the last time I am new to labjack.I have an idea on SPI but the article u-3 guide is not clear to me. And yet, the pins just don't do anything. What are digital I/O? I am pretty new to programming still and do not understand how to make a list of bytes correctly, and I am not exactly what value should be entered for each byte, such as Checksum16. Just tested this with our LabView example. How do I connect the LabJack T-series device directly to my computer with Ethernet? CB15; CB25; CB37 V1.2; CB37 V2.1; EB37; EI-1022; EI-1034; EI-1040 If CPHA is 0, data is valid on the edge going away from CPOL. Datasheets and User Guides. From page 4 of the datasheet it looks like ADIS16210 will work between 10 and 830 kHz. Accessories. The digital I/O use 3.3 volt logic and are 5 volt tolerant. So if you write 16-bits the first 4 are ignored. SPI (U3) has: MOSI MISO CLK CS SSI sensor has: Pulses + Pulses - Data + Data - The SSI protocol is discussed more on page 82 of the attached PDF. Up to 50 bytes can be written/read. 16 are available from the flexible I/O lines, and 4 dedicated digital I/O (CIO0-CIO3) are available on the DB15 connector. 4 discrete I/O-channels. That way we can get support staff assigned to it. 16 are available from the flexible I/O lines, and 4 dedicated digital I/O (CIO0-CIO3) are available on the DB15 connector. So that seems weird, not being connected to an SPI peripheral. Secondly this sensor required clock rate of 830Khz, is LabJack able to operate at this clock rate, Please have a look at the data sheet and advice me how to proceed with my task. What kind of things can be done with a LabJack? We do have an SPI example for DAQFactory.

Ah, sorry about that. The LabJack U3 has up to 20 digital I/O channels. How do I write to internal flash? What are digital I/O? No, the U3 does not support the partial byte feature. I there any guide to learn the syntax of programming in Lab jack? The pseudo code looks to be C, but then it is pseudo. 5.15 - Sharing a particular device among multiple processes or computers, 2.9 - GetFirstResult() and GetNextResult(), LabJackPython for UD, Exodriver, U12 - Windows, Mac, Linux, LM34CAZ Temperature Sensor (Advanced Example), Moving Average: Interval Compute (Low Speed), Moving Average: Interval Compute (High Speed), Zero-Crossing Detection and Pulse Response, LJsimplelog (exe and LabVIEW source) for U12 - Windows, LJstream1 (exe and LabVIEW source) for U12 - Windows, LJstream2 (exe and LabVIEW source) for U12 - Windows, Configuring & Reading a Quadrature Signal, Configuring and Reading Counters [U3/U6/UE9], Configuring and Reading Timers [U3/U6/UE9], Advanced Timer/Counter Testing [U3/U6/UE9], 4.2 - Variable value components for numeric display, 4.4 - Descriptive text components for textual display, 4.6 - Outputting with variable value and descriptive text components, 5.4 - Conditional logging and the export set, 7.5 - Real-time web access with DAQConnect, 10.2 - Reading Values for Counters and Input Timers, 11.2 - Raw In/Out and Other Functions That Require Array Pointers, LJFuse (Experimental / Not Released / Unsupported).
