Problem runing my code

[Archangel]

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

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

You might try this:

main:
For ledvar = 0 to 100
low led
pause 100
high led
pause 100

next ledvar

low led1
For ledvar = 0 to 100
low led
pause 100
high led
pause 100

High LED1
goto Main

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 .

 @ DEVICE WDT_ON, PWRT_OFF,MCLR_ON,CPD_OFF, BOD_OFF, PROTECT_OFF,INTRC_OSC_NOCLKOUT
      Include "modedefs.bas"
      
DEFINE OSC 4
RCSTA=$90'DEFINE HSER_RCSTA 90H
TXSTA = $20'DEFINE HSER_TXSTA 20h
DEFINE HSER_BAUD 2400
DEFINE HSER_SPBRG 25
'DEFINE HSER_EVEN 1
'DEFINE HSER_CLROERR 1 ' Clear overflow automatically
'DEFINE HSER_TIMEOUT 1 ' Clear overflow automatically  

PORTA = %00000
PORTB = %00000010
TRISA = %00000
TRISB = %00000010
intcon = 0		
vrcon = 0
CMCON = 7	     
j var  BYTE
led var portb.7

LOOP:
j = j + 1
if j = 255 then SLP
high led2
HSERIN 10,main,[DEC4 b0]

goto loop

' here will be  my programe 
SLP:
low led
RCSTA.4=0
 pause 100
INTCON.6 = 1
RCSTA.4 = 1
PIE1.5 = 1
PIR1.5 = 0
@ SLEEP
@ NOP
PAUSE 1000
HIGH PORTB.6
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.

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.

@ 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

SLP:
OPTION_REG.7 = 0
RCSTA.4=0
pause 100
INTCON.6 = 1
RCSTA.4 = 1
PIE1.5 = 1
PIR1.5 = 0
@ SLEEP
@ NOP
GOTO LOOP

sorry for asking to much but i really wants to learn pbp very good im reading the whole datasheet every nights it helps and i get to much help and ideas from this forum thank u everyone

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.

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 ...
