Problem with programming counter using Proton

Hi all , i am New here and i have problem with programing counter with proton program , i am using basic language . My project is to use an analoge to digital converter in Pic 16f877a to calculat the temp by using Lm35 and to make alarm when the Temp reatches a certain value, the problem is i canot declare the Puch button to the program , and also i want to know how to declare the puch button to the micro ( Which port ). Plz replay fast Thx :grin:

The program :

Device 16F877A
XTAL 4
LCD_RSPIN PORTC.0
LCD_ENPIN PORTC.1
LCD_INTERFACE 8
LCD_DTPIN PORTB.0
LCD_LINES 2
Dim name As Byte

Dim s1 As Byte
Dim s2 As Byte
Dim y As Byte
loop:
Button 0,0,255,250,name,0,nopress
Print "F"
nopress:
GoTo loop

you can easily use like this other then button command:


or you really want to use button?

goto mywebsite..i have some tutorial off basic instruction you should understand..

thelocxresearch.tk

Thx Alot lockman_akim but i have to use Puch button that what my profesor told me Any way thx alot for reply

start:

Button PORTB.0 , 0,0,0, BTNVAR, 0,nopress
Print "f"

nopress:
GoTo start

Thx again but thats now what i want , i have done this befor several times, i need it when i press on the button prints F, that the New thing in the program

just ad the function below the BUTTON command..

hope it help u..

i did,it print the f , with out pressing

Device 16F877A
XTAL 4
LCD_RSPIN PORTC.0
LCD_ENPIN PORTC.1
LCD_INTERFACE 8
LCD_DTPIN PORTB.0
LCD_LINES 2
Dim BTNVAR As Byte
Dim name As Byte
Dim y As Byte

start:

Button PORTD.0 , 0,0,0, BTNVAR, 0,nopress
If PORTD.0 = 1 Then y=y+1
DelayMS 100
Print Dec y

nopress:
GoTo start

thats what i did

Syntax

BUTTON Pin , DownState , Delay , Rate , Workspace , TargetState , Label

Overview

Debounce button input, perform auto-repeat, and branch to address if button is in target state. Button circuits may be active-low or active-high.

Operators
Pin - a PORT.BIT, constant, or variable (0 - 15), that specifies the I/O pin to use. This pin will automatically be set to input.
DownState - a variable, constant, or expression (0 or 1) that specifies which logical state occurs when the button is pressed.
Delay - a variable, constant, or expression (0 - 255) that specifies how long the button must be pressed before auto-repeat starts. The delay is measured in cycles of the Button routine. Delay has two special settings: 0 and 255. If Delay is 0, Button performs no debounce or auto-repeat. If Delay is 255, Button performs debounce, but no auto-repeat.
Rate - a variable, constant, or expression (0 - 255) that specifies the number of cycles between auto-repeats. The rate is expressed in cycles of the Button routine.
Workspace - a byte variable used by Button for workspace. It must be cleared to 0 before being used by Button for the first time and should not be adjusted outside of the Button command.
TargetState - a variable, constant, or expression (0 or 1) that specifies which state the button should be in for a branch to occur. (0 = not pressed, 1 = pressed).
Label - a label that specifies where to branch if the button is in the target state.
Example

DIM BTNVAR AS BYTE ' Workspace for BUTTON instruction.

Loop: ' Go to NoPress unless BTNVAR = 0.
BUTTON 0 , 0 , 255 , 250 , BTNVAR, 0 , NoPress
PRINT "* "
NoPress:
GOTO Loop

Notes

When a button is pressed, the contacts make or break a connection. A short (1 to 20ms) burst of noise occurs as the contacts scrape and bounce against each other. Button's debounce feature prevents this noise from being interpreted as more than one switch action.

Button also reacts to a button press the way a computer keyboard does to a key press. When a key is pressed, a character immediately appears on the screen. If the key is held down, there's a delay, then a rapid stream of characters appears on the screen. Button's auto-repeat function can be set up to work much the same way.

Button is designed for use inside a program loop. Each time through the loop, Button checks the state of the specified pin. When it first matches DownState, the switch is debounced. Then, as dictated by TargetState, it either branches to address (TargetState = 1) or doesn't (TargetState = 0).

If the switch stays in DownState, Button counts the number of program loops that execute. When this count equals Delay, Button once again triggers the action specified by TargetState and address. Thereafter, if the switch remains in DownState, Button waits Rate number of cycles between actions. The Workspace variable is used by Button to keep track of how many cycles have occurred since the pin switched to TargetState or since the last auto-repeat.

Button does not stop program execution. In order for its delay and auto repeat functions to work properly, Button must be executed from within a program loop.

Thx lockman_akim for helping , thats what i have read in the proton help , and of course it didnot work Thx

yes it work..just put the delay before it start the function below BUTTOn command..it repeatly print f because the debounce off the switch..

do like this:


Device 16F877A
XTAL 4
LCD_RSPIN PORTC.0
LCD_ENPIN PORTC.1
LCD_INTERFACE 8
LCD_DTPIN PORTB.0
LCD_LINES 2
Dim BTNVAR As Byte
Dim y As Byte
clear
start:

Button PORTD.0 , 0,0,0, BTNVAR, 0,nopress
delayms 50
If PORTD.0 = 1 Then y=y+1
DelayMS 100
Print Dec y

nopress:
GoTo start

ok..i think it perfect now..
