    Exclamation Problem runing my code

    im runing this code pic16f628a this is the code for lcd 7 segment with 74hc164,and when i add things like clock or other code it cuz delay and troubles to the lcd routine plz help i want to add my code here conter and clock and some thing else but i want to put them out o0f the lcd 7segment loop or label and dont cuz troubles or delay for lcd routines ...

    Code:
    @ DEVICE WDT_ON, PWRT_ON,MCLR_ON,CPD_OFF, BOD_OFF, PROTECT_OFF,INTRC_OSC_NOCLKOUT
          Include "modedefs.bas"

    ' im trying to add my code here  loop: goto loop, and want the main: label stays workin its for the 7 segment 
    'and i want to add here clock to ???????and other problem my code has delays of pause 1000 and 2000,..
    B0 = 0
    
    loop:
    b0 = b0 + 1 
    if b0 = 9999 then b0 = 0    ' here i will put delays in my code  so it willl cuz   'problems to the main code ..  delays digit blinkin very slow
    GOSUB MAIN

    Default Try this

    Hi Mus.me

    I think it would be helpful if you include a schematic showing how your LCD is connected so other will find it easier to help you :-)

    Is it a serial LCD HD44xxxx or a 7-segment LCD?
    Does it work standalone(not connected to the pic) ?
    Does the LCD work if it directly connected to the PIC
    Which ports is it connected to ?
    The define statements helped me ;-) but I am using a 2x16 LCD but I do realize you may be using a 7 segment LCD

    Code:
    'LCD defines begin here   
            DEFINE LCD_BITS 4 	'defines the number of data interface lines (4 or 8) 
            DEFINE LCD_DREG PORTD 	'defines the port where data lines are connected to
            DEFINE LCD_DBIT 4 	'defines the position of data lines for 4-bit interface (0 or 4)
            DEFINE LCD_RSREG PORTD 	'defines the port where RS line is connected to
            DEFINE LCD_RSBIT 2 	'defines the pin where RS line is connected to 
            DEFINE LCD_EREG PORTD 	'defines the port where E line is connected to 
            DEFINE LCD_EBIT 3 	'defines the pin where E line is connected 
            DEFINE LCD_COMMANDUS 2000 	'defines the delay after LCDOUT statement 
            DEFINE LCD_DATAUS 200 		'delay in micro seconds
    'END of LCD DEFINES
    And maybe connect it as included diagram shows
    in this post that I made (ignore the PIC model , just make sure that whatever port you use you have set if for input eg. TRIS PORTX=%11111111)
    http://www.picbasic.co.uk/forum/showthread.php?t=12179

    I apologize if I have read your post completely wrong :-(

    Hope this helps

    Kind regards
    Dennis

    SORRY ITS JUST 7 SEGMENTS NOT LCD..this is the 7segment schema i did draw sorry i havnt draw it good but im sure thats enought to undersnd its normal 7seg working through 74hc164 shift register and 4 digit pins to the pic .atached them all to portb . it works fine with a counter like b0 = b0 +1 to 9999. but i cant add any pause or delay i need to findout how to run my program apart of the 7 segment routing or loop. <<<< ITS LIKE I HAVE A LED BLINK IN A LOOP AND I WANT TO WRITE MY CODE APART AND LET THE LED BLINKIN WITHOUT STOPING EVEN OTHER PROGRAME IS WORKIN AND HAS ITS DELAYS OR NO OR SOME ITS LIKE I WANT TO RUN 2 THINGS IN 1 TIME 2 LOOPS I DONNO IF TIMRERS WILL HELP OR WAT TO WITH THIS BLLODY THINGS LOL >>>>THIS 7SED GODE WORKS OK THE TOP 1 I POSTED BEFOR ISNT WORKING ANYWAY THANK U FOR HELP

    Question

    i think none understands my quetion.i want to run like this code ..
    i want both programes to run apart from each other its just example so i can write my programe like this plz help
    Code:
    main:   ' i wa]nt this led to blink  forever without any other delay or stops
    high led
    pause 100    
    low led
    pause 100
    goto main
    
    loop: ' and i want this led1 to blink without any other delay or stop
    high led1
    pause 2000
    low led1
    pause 200
    goto loop

    Thumbs down Processor unability ....

    i want both programes to run apart from each other
    Hi,

    With Pics ... You CAN'T do two things at the same time ( say totally independant things - excluding Peripheral use )

    a Pic does ONE THING AT A TIME ... " Multitasking " just is doing a little part of a task, then a little part of another task, then ...... a little part of the first task, then ....

    very quickly.

    thats ALL !!!

    For your LED Example ... you'd have to use a Pair of "555" as EXTERNAL peripherals, ( HPWM modules are too fast ) to drive your leds .

    Alain
    ************************************************** ***********************
    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...
    ************************************************** ***********************
    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    o right thank u Acetronics for reply.check ur pm . it just confused me this 7 sgment it need the routine in main label each 1 ms, so if i put anythings has delays or like serin it cuz the 7seg delay and blinking slow thats im thinkin to define it like lcd or something to kepp the shift out runing each 1 ms .and do my programe works and has delayes,,,,,,,,,

    Hi,

    BUT ...

    I think you could " re write " your project ... showing clearly what you want to do !!!

    refresing your full display @ 200 Hz is not compulsory . 50/60 Hz is a classical value ... that leaves some time in between to do little other tasks ... while a digit is lit ...

    You should Google around For the numerous ( ! ) alarm clock projects on the web ...

    Difficult to help you not knowing what you want to do ....

    You can obtain the two leds flashing at a different interval with a couple of variable:


    Code:
    Dled     Var Byte
    Dled1   var Word
    
    main:   '  led will blink @ 0,1 sec; led1 will be on for 2 secs off for 0,2 sesc
    Pause 1
    
    Dled = Dled + 1
    Dled1 = Dled1 + 1
    
    If Dled =>100 then
    Toggle led
    Dled = 0
    endif
    
    If Dled1 = 1 then high led1
    If Dled1 = 2000 low led1
    If Dled1 =>2200 then Dled1 = 0
    
    
    goto main
    Al.
    All progress began with an idea

    serin porta.0,n2400,[],b0  this serin cuzin delays   so the 7seg led blink and 'stops
    if btN = 0 then b0 = b0 - 1

    Wink "the" peripheral

    as Serin WAITS for the incoming data ...

    difficult to have a precise timing !!!

    HSERIN offers the USART Rx interrupt flag polling ( doesn't stop the program flow ...) AND BYTE "recording" ...

    with a device showing an USART, of course... but the 628 has an inbuilt USART.

    Soooo ... just use it !!!

    WELL THIS IS MY CODE WHEN I CLICK SENT DATA (1234)FROM PC TO PIC16F628. I SEE IT FOR LESS THAN 1 SECOND THEN THE 7SEG GOES OFF TILL I CLICK AGAIN TO SEND I SEE IT JUST BLINK 1234.

    Try to make these two correction to your code:

    D0 = B0 DIG 1
    READ D0,DIGIT[1]
    D0 = B0 DIG 2
    READ D0,DIGIT[2]
    D0 = B0 DIG 3
    READ D0,DIGIT[3]
    
    Skip00:
    
    for index = 0 to 3
    seg = digit [index]
    SHIFTOUT SDO,SCLK,0,[SEG\8]

    Angry i solved that code joe thank u for help

    the big problem i have now is to wake up pic 16f628 from sleep using usart interrupt hserin i tested PIR1 it occur but in sleep mode it doesnt occur . i donno i think im runing usart on synchronous slave mode thats what says the datasheet but i donno wheres my problem .my project is to transmet data to pic then wake it up . here is my code .
    Code:
     @ DEVICE WDT_ON, PWRT_OFF,MCLR_ON,CPD_OFF, BOD_OFF, PROTECT_OFF,INTRC_OSC_NOCLKOUT
          Include "modedefs.bas"

    HSERIN 10,main,[DEC4 b0]
    
    goto loop
    
    ' here will be  my programe 
    SLP:

    PAUSE 1000
    LOW PORTB.6
    GOTO LOOP
    END
    please help i had read all the usart datasheet and i did what it says but nothings i think the problem in sync slave mode or the osc goes off during sleep or usart not reciving data even i did set it to recive data and interrupt..
    and acetronics says (Alain

    ... and now, just use " Wake up on interrupt " ... as you have the interrupt flag !!! i donno where to put on interupt i trayed it many ways but nothings when it goes to sleep it die just like my nan bless her ..

    Mus.me, the time you are using to go to sleep it seems to to be too short. You have 2.5 secs available than your micro enter into the sleep process. I would use a word (J VAR WORD) and set at least 20 seconds, otherwise you cannot even read the display.

    Code:
    LOOP:
    j = j + 1
    if j = 255 then SLP '2.5 secs is a too short time use a word 
    high led2
    HSERIN 10,main,[DEC4 b0]
    
    goto loop
    Remove the two long pause in your code (after sleep command) otherwise when micro wakes has to process the two pauses and will loose the Tx data, and will return to sleep.

    Code:
    @ SLEEP
    @ NOP
    PAUSE 1000
    HIGH PORTB.6
    PAUSE 1000
    LOW PORTB.6
    GOTO LOOP

    thank u aratti for reply i think the problem is in usart when pic goes in sleep mode the something aint working to receive data from PC TX , i tryed everythings 3days now but nothings .here where i have the problem, why it doesnt wake up the chip ?? lol
    Code:
    SLP:
    OPTION_REG.7 = 0
    RCSTA.4=0
    pause 100
    INTCON.6 = 1

    PIR1.5 = 0
    @ SLEEP

    Hi Mus.me,

    I think you should turn on global interrupt enable (GIE) bit.
    Code:
    INTCON.7 = 1
    Isn't that the master switch for all interrupts?

    Mus.me, HSERIN is an asynchronous serial function. You cannot awake from sleep the mcu with HSERIN you should search another way. If you have PortB.0 available then you could use the interrupt on portB.0, for instance you could connect RTS pin to portB.0 (via a level translator) and before TX you pull high RTS to wakeup the pic.

    Actually on a 16F628, the USART can wake the PIC from sleep... I'd handle it outside of HSERIN though (you wouldn't be able to put the PIC into SLEEP initially from inside HERSIN anyway).

    Hi, Mus

    I played a bit with the HSERIN Command ... but Wake up only works in Synchronous mode ( roughly consider USART is disabled when sleep mode ... as the system clock is ... down !)

    sooo ...

    last option is to use a comparator interrupt: tie the comparator input to RX Pin ( seems Porta is unused ...) and use the comparator interrupt for wake up ...

    Mus.me,
    Serin2 SI,N2400,[B0] is wrong. For 2400 bauds use : Serin2 SI,396,[B0]. The same apply for SEROUT2.

    Do you use hyperterminal for RS232 com with the pic?

    ...... I SEND 5 TIMES OR MORE THEN IT RECEIVE THEM 1 TIME ....????????
    WRITE 5,B0 'SAVE NUMBERS IN EEPROM

    You are writing "5 TIMES OR MORE" in the same location, so at the end you will see only the last byte Txed.

    Mus.me, all the ascii from 0 to 31 will give you wierd symboles, and 32 will show nothing because is space. This is the reason why you use the notation DEC before the variable to Tx.

    If you want to receive both decimal and ascii you can Tx twice the variable

    Serout2 SO,390,[DEC B0, " ", B0,13,10]

    or you can select in which format to send out the variable depending on its value

    IF B0<33 Then
    Serout2 SO,390,[DEC B0,13,10]
    ELSE
    Serout2 SO,390,[B0,13,10]
    ENDIF
