You can do this from Windows by selecting Start»Programs»National Instruments✽istributed System Manager, or from LabVIEW clicking Tools✽istributed System Manager. This tab includes the total and available memory, as well as the total disk space and the amount of free space on the disk.Įxternally with the NI Distributed System Manager (DSM) (LabVIEW 2009 or later): In the main window, select the System Settings tab.Expand Remote Systems in the Configuration window.You can do this by selecting Start»Programs»National Instruments»Measurement & Automation.

For more information about how to use the Hardware and System Property Nodes, refer to the Resource Monitor.vi example in LabVIEW by going to Help > Find Examples. and once the NI Example Finder loads, browsing to Hardware Input and Output > System Configuration.Įxternally with Measurement & Automation Explorer (MAX) (Memory only): Using the System Configuration API, you can use the System Property Node get memory usage information using the System Property Node to get memory usage information and the Hardware Property Node to get both memory and CPU usage details. Programmatically with LabVIEW 2012 and Later:
Refer to the Memory Reporting Issue with NI Linux Real-Time OS Target for information on how to implement memory monitoring. Externally with the Real-Time Trace Viewerįor Linux Real-Time controllers, memory management and reporting differ from other Real-Time targets.Externally with NI Distributed System Manager (DSM) (LabVIEW 2009 or Later).Externally with Measurement & Automation Explorer (MAX) (Memory only).Programmatically using LabVIEW 2012 and Later.This guide will walk through different methods of accessing this information from a Windows operating system:
Cpu and ram monitor software#
The amount of memory available depends on several factors, including the installed software and user application memory requirements. Worst case scenario, you can use a tool like hwinfo with the option to log to file the measurements and run it in background, and every few seconds you parse the log from hwinfo and extract the info you want.There are varying options to monitor CPU and memory usage on an NI Real-Time (RT) Controller. There's freeware/open source tools and some info is available through windows api.
Cpu and ram monitor serial#
The benefit is you can also use the 5v from USB cable to power your board.Īnyway, from this point you can write a small application that reads the temperature or fan speeds from somewhere and formats it into some format your arduino understands, sends it through the serial port. You can buy USB to Serial converts that directly output Serial TTL (the 5v version that works directly with microcontrollers), here's examples: Microcontrollers output 5v for 1 (or whatever the voltage the micro is powered with), so if you want to connect directly to the PC, you need to convert this 5v and 0v to -12v and 0v, using a transceiver chip.Īn example of such a chip is MAX232 and here's a schematic which powers the chip from the serial port and converts the negative voltages to 5v : Serial ports use a negative voltage for digital "1" and no voltage for 0. If your pc no longer has serial ports, you can buy a usb to serial adapter cable / device which creates a serial port. Modern computers may or may not have serial ports. Then, an application on your PC can periodically send the info to your Arduino, which then displays it on screen.
The easiest way to connect your Arduino to the PC is through a serial port.
