Ioannis, would you mind explaining that code a little bit to me? I'm a bit of a newbie and haven't dealt with a lot of different code. Is it as simple as copy and pasting in ....


For...

Not to bring up a dead subject, and I am not sure if anybody is going to have any interest in helping out. But if I am using a code similar to Alain's that he posted above ^^^, how can I slow down...

Alain,

Thanks for that code. I had some of my own code that was partially working (servo would only go one direction) that I was in the lab troubleshooting right now. But, I think I might break...

Ok. I wasn't thinking about the load on the servo. What I think I'll do then is put the pulse that controls the "zero" position in the loop that is waiting for the button to be pressed (so that it is...

Thanks for the help. That makes sense now that I think about it. The timing of it was probably the biggest problem I was having.

With moving the servo back to its "zeroed" position- I was...

I have a pretty simple process that I need carried out via a 16F88 and a servo.

I have an arm that has a heating element on the tip of it. I need this heating element to be lowered onto a bed of...

What I've done with my projects when using a 16F884 is follow the general command of LCDOUT. I copied the code from my last project, I think it should work the same for you. So if I had a value...

Are you using a serial LCD or a 8-bit/4-bit set up for the LCD?
If using it in 4-bit or 8-bit you should be able to do.

LCDOUT $FE, 1, "Hello"

'example code that...

Thank you all for the help.

I'll explain to all of you what this is all for. What I am have been building this semester is a open circuit wind tunnel for a mechatronics class. We have several...

Fellas,

I am having a problem with my LCD display that I can't seem to figure out what the deal is. I have a 16 x 2 LCD that has a Hitachi 44780 driver. I am having problems with the value it is...

Paul, that fixed the problem. Thanks again.

Hopefully this all works as planned now!

Thanks, Paul!

I'll give that a try when I am in lab tomorrow morning. I also got my op amps today so hopefully I can get my pitot and up running tomorrow!

Or, here is this to make it easier to read.


'Using PIC16F88
'Identify and set the internal oscillator clock speed (required for the PIC16F88)

'Using configuration bits of the following...

So, after working it over a little, this is what I've got.



But, now I am getting an error. I believe it is with one of my eqautions but I am unsure why. The error I am getting is....


...

Thanks for the help you guys. I'll look through the code and try to decipher what exactly its doing and make sure I have it set up for my application.

Is the serout2 command just sending the data...

Thanks for the Help.

So, I got the op amp all set up to keep the voltage under five volts. I can't believe I let that slip my mind when I was setting this up.

Now, for coding, to get the...

Oh jeeze. I should have realized that... okay. Well I can fix that by bumping down the gain on the op amp by swapping resistors so that's not a problem. I'll work on this and see if I can't get...

Dave,

Thanks for your help. That makes a huge difference. Few questions for you though. Since this sensor will never hit it's maximum pressure reading at any point, is there a way to cut the max...

Hey All,
I am working on a project to calculate the airspeed from a pitot tube that is connected to a differential pressure sensor (MPX5500DP) and then output it to an LCD screen (44780 Driver) ...
