LCD Display Labview

[Martin88]

Hi Forum,

first thanks a lot for all your help! I am using Labview for power monitoring on a mini pc running windows 7, i wanted to display the different states on a  HD44780 LCD mabye also controlling two buttons. 

Would be great if someone can give me some ideas how to do this and how difficult it is. 

Thanks a lot

Ok, the HD44780 is basically a chip. Are you getting it as a part of a display board or are you building up the whole thing yourself.

In any case, the chip is designed to sit on a processor bus, but you can use DIO ports to emulate a bus. You might want to consider getting it on a card that incorporates a little intelligence and can offer a serial interface.

An arduino can be used for this.

Hi,

ok if i use an adruino i would sent the data from the pc  to adruino and then display it on the LCD or how i could do this?

I found a lcd for windows here http://www.mini-box.com/picoLCD-20x2-OEM?sc=8&category=490 it has  usb connection and driver for windows how about this.

With the arduino, I believe you would just send the text messages to it over a serial port connection. The other uses USB HID which might be a pain. HID covers a lot of different types of devices (keyboards, mice, etc.) but I've never tried to program a HID display from LabVIEW.

Hi Dennis,

i think the adruino idea sounds like a  good fit, i will go with this. So i may use the adruino toolkit from ni to communicate between the pc and the adruino? 
Thanks

Could you keep us updated?  Sounds like an interesting project.  🙂

You would probably need to modify the arduino code but it looks like the code is available.

Given the programmability available with the arduino, are there other things you could use it for? It would be a shame to use is as just a display controller.

Arduino is good and simple. You dont need to do much work as LCD code is readily available. But arduino is costly solution. If you can do some hardware and program then you can use MSP or PIC or other for that. These ICs have 2 UART, from one UART you need to receive data from LV to display on LCD and other UART you going to send these data to LCB. But this needs more effort but this is cheaper solution.

Its all up to you but as told keep us posted becasue this is an interesting work.....Good one
