how to create condition loop?

thank you so much.. one more question is if i want to put a jpeg camera, is it possible with LIFA? and how should I do connection?

What kind of camera are you trying to implement?  LIFA doesn't do cameras.  USB cameras work with LabVIEW, you simply need the Vision module for LabVIEW.

I using JPEG camera.. oh no.. so LIFA cannot support JPEG camera? Can advise what else application can add to this project? thank you so much and appreciate your help..

[Nathan_B.]

JPEG is an image format so we can't really know what you mean by "JPEG camera".  There are several different types of cameras.  The most common is a USB camera (e.g. webcams) but there is also Serial and network cameras.

I've read somewhere that there are some cameras that can interface with Arduino but it's not a USB camera and the Arduino can't handle all that much data.

LIFA was not designed for any cameras or image processing.

hii again. I add LCD into my circuit to display temeprature every second (FALSE case), while display "FIRE!" if is TRUE case. How should i modify the circuit so that the value from the sensor will link to the LCD. Appreacite so much for your help! thank you!!!

[Nathan_B.]

If I understand you correctly, you just need to convert your temperature into a string so that you can pass that to the LCD display VIs.  You can do this with "Number to fractional string".

still i not able to get it.. all sensors value go wrong.. can help me on the circuit on how to display the temperature on lcd? thank you so much!

[Nathan_B.]

What do you mean by "all sensors value go wrong"?  Are the values correct in LabVIEW?  Were you able to get the LCD to work with other text?

[yee0722]

The temperature sensor will show extreme high value (1000+), and smoke sensor too, when the lcd is connected. Soory, what u means LCD work with other text? I have try the LCD 4 bit hello world example and it works well, but don't know how to connect to display the temperature value. hope you can help. thank you!

Hi.. sorry for keep asking question.. I set my case structure if case TRUE, LED and buzzer will light on; if case FALSE, LED and buzzer will switch off. It works fine for both the case. But when press STOP in TRUE condition, the LED and buzzer will keep light on. How to make the LED and buzzer to switch off once i press STOP button? thank you...
