Problem runing my code

[Mus.me]

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 ...

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



'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

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

i want both programes to run apart from each other its just example so i can write my programe like this plz help

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 .

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,,,,,,,,,

[Acetronics2]

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:




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

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 !!!

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 ..

[aratti]

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.



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.

Hi Mus.me,

I think you should turn on global interrupt enable (GIE) bit.

INTCON.7 = 1
Isn't that the master switch for all interrupts?

hello Gusse thank u for help , i did that not working, i think i have problem in slave senchronous or somethings goes off when sleep mode .im sending 4 numbers from the pc and it works great .but in sleep mode it doesntwake it up

[aratti]

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.

Al.

[Melanie]

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).

[Acetronics2]

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 ...

Alain

Thank you all for help and i will satill trying everythings to get it works.my project i want to buil is to control a cam and transmeter and some hardwares away from me and to shut them off and the pic to .so when i wake up the pic i send data to start the tranmeter and other hardware i will use the relays , i know how to do it but i need to save energy bcz the elctric goes off sometimes when its raining or windy thats why i want to put everythings shuted off and pic in deep sleep lol. THANK U ADAIN N MY WISHES

[Mus.me]

Hi again i did tried portb.0 with rx using led it works good , but if u tried by resistor or sometthing else it will wake up pic but no data receiving from usart .well thank u everyones for helping me.

HELLO EVERYONES AGAIN LOL, IM TRYING TO SEND DEC NUMBERS FROM PC TO PIC BUT I DONNO HOW TO WHY WHEN I SEND EX: 15 IT STORES $60 IN EEPROM OR DEC 20 IT STOR $08 . AND IT STUCKS


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.

thank you aratti im using serial communicator in microcode studio . But still gettin wiered symboles when i send from pic to the pc . I want to send dec and ascii but i donno how

...... But still gettin wiered symboles when i send from pic to the pc . I want to send dec and ascii but i donno how

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

thank you very much aratti for ur help .i tryed it whith baud 16780 it works good i send from pc to pc and from pic to pc its the same i get using serial communicator of microcode studio .i will try with transmeter and receiver bcz i tryed it using ir it does error .got a amall robot to test likw remote control than i carry on have agreat day ARATTI ...

HI ARATTI,

I DID THIS CODE IT WORKS GREAT THNK U FOR HELP

SYNC CON "A"

SO con 1
SI con 0
B0 var WORD
B0 = 0
MAIN:
Serin2 SI,16780,10,MAIN,[WAIT(SYNC), DEC4 B0]

SerOUT2 SO,16780,["OK MUS ..! ",DEC4 B0]

GOTO MAIN

NOW IM TRYING INFRARED BUT STILL NOT WORKIN I KNOW IR RUNS ON 40KHZ, AND IVE GOT TRANSMITTER AND RECEIVER I FOUND THEM IN PROBASIC STATION METEO WAS SENDING FROM OUTSIDE TO THE CLOCK IN MY ROOM I TOOK THEM OFF BUT AINT WORKIN .
