wha

accessing parallel port I don't have a problem with, but what I need is to use 3 parallel port pins as I/O pins, i.e. I need to send a pack of 0's and 1's to one particular pin only (lets saypin 2) because I don't want to use the hanshaking signals etc on the paralel port. Also I need to recieve a signal HIGH from the Hall affect where in computer language that would be 1. Would anyone happen to have an example??

Thanks in advanced

Hi zero............

here one more example - how to talk to chip via SPI ( eg. g. 16Bit)

Hope this helps to understand the sequential Operation with LPT - Port

Hi down under,

I had a look to the original vi - it is written in a very bad style - using no loops etc.

Unfortunately I cannot open your vi - I use LV7.1.1 @ the moment

What I can offer is a vi - written for MAX168 - a 12Bit serial ADC using the LPT - Port.

It is tested and worked perfect in the past for me. From there you can go ahaed and

make changes for yor ADC.

The Datasheet of MAX168 find @ MAXIM

Hope this helps

Hi Rodolfo,

my first thought was - why don't you use the OUT PORT.vi from Functions Palette / Advanced / Port I/O

Why do you talk to an 8 Bit Port with 32 Bit ??

Find attached - in LV7.1.1 - a simple LPT - Test.vi......... already prepared for your LPT 3 - Address.

Hope this helps.
