dumb question

**mackrackit** · - 23rd August 2009, 00:24

For now use Micro Code Studio and MPASAM as the assembler. I am hearing about problems with MPLAB right now.
The file you need to comment the lines in is in the PBP directory.

Assuming you have the 16F690.inc file commented on the correct lines like the above thread shows... This code should have a couple LEDs blinking.

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
      
    'The first line is if you are using PM, the second if you are using MPASAM
  '  @ device  pic16F690, intrc_osc_noclkout, wdt_on, mclr_on, protect_off
    @ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF
  
    'VARS
    LED1    VAR PORTC.0
    LED2    VAR PORTC.1
    
    START:
    HIGH LED1
    LOW  LED2
    PAUSE 250
    LOW  LED1
    HIGH LED2
    PAUSE 250
    GOTO START

This should do the same as the above code but in a different way.

Code:

'16F690 DEMO_2
  '  DEFINE OSC 8       'Comment the 4Mhz and uncomment these for 8Mhz
  '  OSCCON=%01110000

    DEFINE OSC 4           'This is the default setting
    OSCCON=%01100000
      
    'The first line is if you are using PM, the second if you are using MPASAM
  '  @ device  pic16F690, intrc_osc_noclkout, wdt_on, mclr_on, protect_off
    @ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF
    
    TRISC = %00000000   '0 will make the pins an output, 1 will make them inputs
    
    START:
    PORTC = %00000001
    PAUSE 250
    PORTC = %00000010
    GOTO START

I do not have the demo board that you have, so I hope I did not make a mistake.
Play with these and look in the manual to see how to add a button for an input.
Then change things so when the button is pressed the LEDs blink differently.

Ok,I think we miss a lesson first of this:how to use Micro Code Studio,how compiling a file and how convert it to hex files and after load it to chip

**osceola** · - 23rd August 2009, 00:54

I compile that code with Micro Code Studio and
at the first cod only blink Led no2 on the board without pressing nothing
at the second code stay On Led no1 without pressing nothing
and in the compiler I got this error when compiling
Error LED2.ASM 49 : [235] opcode expected instead of '_config
Im using Micro Code Studio with PICBASIC PRO Compiler Demo

**mackrackit** · - 23rd August 2009, 01:15

In MCS on the toolbar click View then go to Compiler and program options. Then go to the Assembler tab. You pick MPASAM there. If the box is unchecked then PM is used.

**osceola** · - 23rd August 2009, 01:27

Ok done that,have you read my previsious post before posting?I did compile it with PM,got some errors in it but at the end got some results

**mackrackit** · - 23rd August 2009, 01:44

Using PM.
Did you change the code to work with PM. The way I have it posted it is for MPASM.
Maybe I confused things the way I did it. I was wanting to show both ways.

**osceola** · - 23rd August 2009, 03:14

Yes,I change code,but would be easy for start with using just 1 tipe of code.Thank you

**osceola** · - 23rd August 2009, 14:52

Whats next ?

Post your code so we can take a look.

**osceola** · - 23rd August 2009, 16:08

I have compiled and anssemblex and importing hex file in pickit2 and write to PIC.with this code only the second Led from the board is blinking and when press buttonthe Led is not blink.
[code]

**mackrackit** · - 23rd August 2009, 19:00

Did you comment the lines in the 16F690.inc file that is in the PBP directory? Like the config thread pointed out.

In MCS do you have the box checked to use MPASM?

In MCS box in unchecked,and where do I find the .inc file of PIC16F690?

**mackrackit** · - 23rd August 2009, 20:06

The default install of Pic Basic Pro is in C:\PBP. That is where you will find all of the *.inc files for PBP.

**osceola** · - 23rd August 2009, 20:21

I cant do it because I have the demo version of PBP,is other way to do that?

**mackrackit** · - 23rd August 2009, 20:57

I have not had the demo version for a long time. I think the only thing you cannot do with the demo for the chips it supports is write code over a certain size.

The install directory might be named something else though, so you will have to look around.

I dont understand nothing,so hard is it to create a code?!?...or I am really dumb?

**mackrackit** · - 23rd August 2009, 23:32

You are not following the directions. Go back and read all of the links and post.

Why do you need the card reader in the first place? Seems like a lot of work.

**osceola** · - 23rd August 2009, 23:46

Maybe you are right that Im not folowing the corect line of instructions,but my english is not so good and were are many explanation I dont get it.Would be easy if somebody could tell me in little words what to folow,I know how stressfull can be when you explain to somebody something and dont get it and you have to explain again and again....Honestly I really dont know were to start from

**osceola** · - 24th August 2009, 00:22

Anyway...I want to learn and will do that again,thank you for helping me

**mackrackit** · - 24th August 2009, 00:47

Keep reading and trying. The LEDs will blink. But I would put the card reader on the back shelf for awhile.

**osceola** · - 24th August 2009, 21:42

Thanks for being patience,at the end I did it!But with this code one led stay on,and wit other code I will post one led is blinking.whats next?

Do you have MPASM installed? Does not really matter for this stuff but you will need it later.

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.
Sorry but didnt get this:And you were to work on a button part of the code to change the way the LEDs blink.
To work where?Do I have to change something?

..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

To work where?Do I have to change something?

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.

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:

**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

**osceola** · - 25th August 2009, 19:22

Thank you!

**osceola** · - 25th August 2009, 21:28

I have compiled this and dont know why only 3 LEDs are blinking and the 4th doesnt blink.Could you tell me where I am mistaken,to understand better.Thank you

Decimal 4 equals what in Binary?

That brings us back to:
what does this do?

Code:

PORTC = %11100000

you have it in one of your codes.

**osceola** · - 25th August 2009, 23:03

Decimal 4 in Binary is 100.Sorry but dont understand,you said nothing about decimal to bynari conversions

You are correct on bothe accounts. It is 100 and I did not say anything about conversions. But you put LEDS = 4 in your code and I have asked you twice about a other line you wrote and you have not answered.

And you have not shown any attempts using the button on your demo board as an input.

You said you wanted to learn. Have you been studying the PICs data sheet and the Pic Basic manual? It looks to me like you have not.

So what do you really want? Do you want to learn or have someone write your code for you?

**osceola** · - 26th August 2009, 11:44

I dont want to be rude,sorry,but seems hard to me or I am really dumb and dont understand.I have a code witch I find on Microchip website,just want to modify it to write data to EEPROM-and for that I have to learn a lot,I have less then 2 weeks remain to present the project and Im going out of time...As you said,would be easy if somebody write the code,but I dont know who will do that,maybe somebody who wants to help me
