Why only one LED? You should have two. And you were to work on a button part of the code to change the way the LEDs blink.

Yes,I have it installed,I think,is the one with comes on cd with PICKIT 2? Is named MPASMWIN?If is this,yes,I have it installed.

Ok,I did it now,I ansemble the two codes toghether and now are blinking both Leds.

Code:

With this code is blinking LED 1 and 2

**osceola** · - 24th August 2009, 23:30

With this code is blinking LED no.1 and 4.

Code:

'16F690 DEMO
  '  
    DEFINE OSC 8       'Comment the 4Mhz and uncomment these for 8Mhz
    OSCCON=%01110000

    PORTC = %00000010
    GOTO START

**osceola** · - 24th August 2009, 23:34

With this code is blinking LED no.1 and 3...and also change timer to 500

Code:

'16F690 DEMO
  '  
    DEFINE OSC 8       'Comment the 4Mhz and uncomment these for 8Mhz
    OSCCON=%01110000

    PAUSE 500
    PORTC = %00000010
    GOTO START

**osceola** · - 24th August 2009, 23:41

..and here I change PORTC order , timer and Leds:

Code:

 '16F690 DEMO
  '  
    DEFINE OSC 8       'Comment the 4Mhz and uncomment these for 8Mhz
    OSCCON=%01110000

    DEFINE OSC 4           'This is the default setting
    OSCCON=%01100000
      
    @ device  pic16F690, intrc_osc_noclkout, wdt_on, mclr_on, protect_off
  
     TRISC = %00000000   '0 will make the pins an output, 1 will make them inputs
     'VARS
    LED1    VAR PORTC.0
    LED2    VAR PORTC.3
    START:
    HIGH LED1
    LOW  LED2
    PAUSE 250
    LOW  LED1
    HIGH LED2
    PAUSE 1500
    PORTC = %00000010
    PAUSE 1500
    PORTC = %00000001
    GOTO START

Now you have to write your own code so when you push the button on the demo board a different set of LEDs blink. The manual will be a help while doing this.

The code you have posted has two oscillator settings, you only want one.

**osceola** · - 25th August 2009, 11:14

Witch manual?And isnt the way I did it before right?

**osceola** · - 25th August 2009, 13:01

I create this code,after the model you send me,but just to understand,I would like to know where do I have to make changes -because now is blinking one LED and then 3 LED at time:

Code:

And here the LEDs blink in other way:

Code:

**mackrackit** · - 25th August 2009, 14:01

What does this do?

Code:

PORTC = %11100000

The manual you can not find is linked on the page where you got your demo.

This page has samples that you need to work through and understand
