Thanks for the help. I am going to try them both to see which is better for me. I appreciate it a lot.

Hello all,

I have been searching through the forum looking for a way to measure frequency. I found the Pulsin command but it may not be fast enough. I am using a 16f876a @ 20mhz. I will need to...

You can serial in the data into an array. Use the serin2 command. Inside the brackets, skip the number of nubers, letters, ect that you don't want. Then place the following data into an array. ...

If you look at the NMEA format, I believe that those figures are in there. Serial in the data into an array. Then just send those parts of the array to the lcd screen, or led segments.

I know the keyfob is not a rolling code. It is fixed. I am just trying to find a way to hardwire to the alarm. I wanted to interface my carpc to the alarm. I really don't want to have to use a...

Well sorta. Here is what I am wondering. I have a car alarm. It is enabled and disabled by a rf keyfob which happens to operate at 303.875 mhz. In the keyfob, there is a pt-2240-d3 chip that...

I realized that the pause in trying's loop paused for 3 seconds. I changed the loop structure a little though I haven't had a chance to check it yet. Here it is:

That thought had crossed my mind. The problem is I know absolutely nothing about interupts or the pre-scalar settings. I tried to learn about them early on wheh I was building the timer example that...

Hello all. I am wondering if anyone can provide some programming advice. I am looking for a way to provide a time-out for a program. I would like for the program to wait for a user to push a...

I think that the professor is using "program" loosely. You will write the time and date therby "programming it".

If I am not mistaken, bernouli's principle states that as flows across a wing, lift is generated based on the fact that as air flows over the top, it has to flow faster which makes the psi go down...

I work with a patent lawyer here in the US. In the US, you can do something called a disclosure. It is a poor-mans patent in a sense. What you do is send the patent office a disclosure of what you...

Well being as I have experience in fluid measurement here is an idea. May be invovled but it is used in high precision applications.

Air is a fluid. As the circumference of a tunnel decreases,...

I have read that serial cables should not be longer than 100 feet. I have read 5 volt serial data at fifty feet with cat5e. Hope this helps.

Select case dtmf ' dtmf is the variable that I am comparing the cases to
case "1" 'this says if dtmf = "1" then

I found the problem. The isd chip is not playing the error or menu message. I put a led in those routines. I know now that the program is getting through them I guess I am not interfacing with the...

I assume here that when you say index number you mean a binary repesentation of that number. Does this make the pic run smother? By the way, I finally got your code to compile. It won't announce...

Unfortunately, you are beyond my knowledge level. I am a semi-newbie. I read the datasheet and noticed that some of port b has a/d capabilities. That is probally why the adcon1 = 15 worked. ...

Adcon1 should set all of port a to digital. Is there a good conection on porta.5?

I just wanted to let you know that there is pre-written code for this chip. Go here:

This might help.

I have no clue. Sounds like a Melanie or Bruce question. I think that it starts at the zero axis and stops on the turn down or turn up, but I am not for sure.

Sorry,

Travin

Is that your entire code. You might want to try and establish a know condition of the pins at the beggining. What osc are you using?

cmcon=7
adcon1=7

trisa = %00000000 ' makes them...

I guess I am just confused here. The led subroutines are merely a visual aid for the debuggin process. I have about 10 different program written for this contraption. I started with each section...

Pin a.4 is an open drain. Read page 11 in the PBP manual if you intend on using that pin as an output.
