Firstly THANK YOU TO ALL.

The book i have demonstrates the Assembly language and each chapter
increases the knowledge depth. However i think i do not understand as much
as i think i do. I am Proud to say i figured the inputs and outputs and
using the data sheet assigned one of the input/output pins for the RB4
Switch and RB5 for the LED. I am currently looking at Interupts to see if i
can make head nor tail of them and hopefully the interupts would then break
into the program and do what it should do if the switch is pressed. If this
works i guess i put my increment count into the interrupt routine and then
when its finished or back to 0 or off then the rest of the program would
continue. Right now the header for the book puts A and B as outputs, do i
just change RB4 to a input or and if so how without setting bank B to all
inputs. This has stumped me for a an hour now. I have a day off and i said
to my wife i would paint but this has been taking me over all day so far.

Thanks again

Just to update, I am hopelessly new and lost. I was a VB basic guy years ago
and remember a little of what I need to do but not a lot.
I know I will need a place to store the count, and will have a call list up
to 50 so when the count equals 10 I will have a call to put 1+0 on the
screen.
How do I :
Create a place to store the count.
Increment 1 to this count when the state changes
compare the stored count so when it equals 50 I increment the lcd by 1

I was hoping to find a piece of code out there in Google land to help me but
as of yet I have not been successful. However I do feel a sense of
achievement coming this far.

Any help is of course appreciated.

Thanks

Paul



Hi all.
I am trying to make a switch counter that would put on the lcd screen how
many times /50 the switch has been opened/closed.

I purchased the Book PIC In Practice and have been successful in building
the LCD circuit 2x20 and able to put the words I need to the screen. (after
spending hours trying to get it to work)

What I need and am hopelessly lost at this point, is to count the switch on
A0 and put the amount on to the screen. using the lcd Code in the above
book.

I beg you, this is not for any other purpose than to count the water gallon
usage in my house using a hall effect switch on the meter.

Can anyone help me with code/ suggestions etc

Thanks in advance

Paul
