Hi mackrackit,

I've been busy working on the last assignment....

Quick question. Would the code (below) output the value of B_P onto my LCD? B_P is a VAR WORD. I've used DEC1 as I only want to test the output with a couple of button presses (if that makes sense).

 LCDOUT $FE,1
LCDOUT $FE,DEC1 B_P

Well... what did you get on your display?

B_P = 12345
LCDOUT $FE,$C0,DEC1 B_P 'Displays 5

LCDOUT $FE,$C0,DEC2 B_P 'Displays 45

LCDOUT $FE,$C0,DEC3 B_P 'Displays 345

LCDOUT $FE,$C0,DEC4 B_P 'Displays 2345

LCDOUT $FE,$C0,DEC5 B_P 'Displays 12345

LCDOUT $FE,$C0,DEC B_P 'Displays 12345

Hi mackrackit,

Really sorry for the late reply, has been one of those days today.

I've got a couple of small problems with LCD / Counting at the moment, nothing I shouldn't be able to fix by now so please bear with me. If I can't get it going soon I'll have to ask.

Days???
I have been having one of those weeks

Hi mackrackit,

I have been having one of those weeks

Lol..... Nice to know I'm not alone, you do have my sympathy though.

Here's what I thought was a silly question, now I'm not so sure it is:

When you declare a VAR WORD, I thought that the value would automatically be set at zero, now I'm not so sure it is. Do you have to have to re-set it to zero before you start a count program or is it zero already?

I know it's Friday tomorrow but I hope your week gets better.

Dave

[mackrackit]

Sometimes it will be zero at power up but you never know.

You can use CLEAR, in the manual

or

VAR_IN_QUESTION = 0

Not a stupid question at all

Not a stupid question at all

Cheers mackrackit, I'm feeling better already I hope you are too!

So probably good practice to set VAR_IN_QUESTION = 0 just in case.

Hopefully I'll have moved the program on tomorrow, fingers x'd.

Right, time for me bed.

See you tomorrow.

Hi mackrackit,

Question: How long does it take LEDave to wire a push_button_switch to a PIC16F684?

Answer: About 48hrs

I think the program below should work ok:

Total var word
clear

MAIN:
if PORTA.5 = 0  then  count_up:
IF PORTA.5 = 1  THEN      MAIN: 
    
Count_up:
let Total = Total + 1 
pauseus 25   
LCDOUT $FE,1
LCDOUT $FE,$C0,DEC Total
PAUSE 500    
GOTO MAIN:

LEDave current status: Eyes going, mind boarderline!
