POOKECODE and PEEKCODE

[MINHLE]

HI,

my PBP does not recognize the PEEKCODE and POKECODE. so any hint can help
thanks

Hi, MINHLE

Will you post a relevant piece of code ???

Alain

[MINHLE]

the code is very simple. but the words: peekcode and poke code are not bolded and capitalized automatically (i.e. they become: PEEKCODE and POKECODE
----------------

CMCON = 1
TRISA = 0
TRISB = 0

I VAR BYTE
OUT_STORAGE VAR WORD ; OUTPUT STORRAGE TEMP.
address VAR WORD

LOOP:

PORTA.1 = 1 ;RESET 4017
PORTA.1 = 0
PORTB = 0 ; set port B all zero
address = $11 ; storage data location beginning here



FOR I = 0 TO 1 ; loop 2 times

peekcode address , OUT_STORAGE ; retrieve data ready for output
PORTB = OUT_STORAGE ; output data by port B
address = address +1 ; fetch the next data
PAUSE 10 ; pause for 10ms
CALL CLOCK ; call clock of 4017

NEXT I

GOSUB LOOP

clock:

porta.0 = 1 ; clock the 4017
@nop
porta.0 = 0
RETURN

END

pokecode @address, $55,$2A
;
;note that the peekcode and pokecode is not capitalized and bolded automatically as the other keywords i.e. PEEK or POKE

Hi, MINHLE

1) address = $11 ; storage data location beginning here
pokecode @address, $55,$2A

Very Strange ... as the table might be located at the program END ( see manual ... ) you are right into the PBP "macro" 's locations !!!

2) Those commands did not ever exist ... which version of PBP do you work with ???

Hello,
the manuel said place the pokecoke after the END "FOR THE REASON OF INTERRUPTION OF FLOWING PROGRAM".

anyway, the PBP does not recognize the functions PEEKCODE and POKECODE. then issue the compile error

whatever wrong with the code, the keywords should be in upper and bold automatically, similiar to other keywords or functions

in this case i assume there are no such FUNCTIONS IN THE PBP COMPILER.

THANKS FOR YOUR ATTENTION,
i keep looking for answer

p/s the version i do is 3.0.0.5

Question 2 was ...



2) Those commands did not ever exist ... which version of PBP do you work with ???

[MINHLE]

hello Alain,

in the PBP the version is 3.0.0.5. (melab programmer and Picbasic pro compiler)
and also in the manuel book mentions to those commands.


thanks Alian,

... soo simple

Pokecode DO NOT accept a variable as address ...

Obvious !

Once corrected ... compiles fine.

thanks ,
i try it

Hello agian Alian,

if POKECODE does not accept address avariable it becomes POKE.

in the case, i store serveral data in the POKECODE function.
i try it but only the datum stored at the specific location is shown up i.e at the location $11 that is $55;

i.e. i can write: POKE $11, $55, $2A

The output is only $55 (after compile)
but if i wrire

POKECODE $55, $2A ( location address is empty or a constant)

PEEKCODE ??? , OUT_STORAGE ( ??? Mean which address: the first datum is retrieved only, that is $55

and in case i would jump to the second location to pick up the datum (i.e. $2A) of that location how can I do?

I believe i do not have those functions?

thanks

Really interesting point of view ... "this explains that ... "

have a good evening.

Alain

[MINHLE]

hello ALain,

youa re right.

the variable does nothing on the POKECODeE. after refresh my mind i relize taht. misunderstanding the address

thanks again for your help

regards,

the address

Hi, Minhle

May be you might try the WRITECODE Command

a good night somtimes Helps ... to understand what is looked for. LOL

[MINHLE]

Hello Alain,
thanks, both EEPROM and DATA, WRITE and READ are work well

hi ,can someone help to see where is problemes are
the output is only the first byte of data stored in a table
pic16f877A

ADCON0 = 0
ADCON1 = 7
define osc 20

trisB = 0 ' SET PORTB AS OUTPUT
PORTB = 0 ; SET PORTB t and C to 0
trisc = 0
portc = 0

trisd = 0 ; 2 pins of this port is for reset and clock


erasecode $500 ; erase code space @$500 (page 0)

B0 var word
StrAddr var word
F0 var byte
E0 var byte
k var byte
LOOP ; this loop display the value stored in the flash
b0 = 0 ; initial value
FOR StrAddr = 500 to 505 step 2 ; read a word
call display
NEXT StrAddr
goto loop
'--------------------

DISPLAY:
Peekcode StrAddr, b0 ; fetch a value from table
f0 = b0.lowbyte
e0 = b0.highbyte
call output1
return

'-----------
output1:
for k = 0 to 30 ; output 2 ports of B and C
call reset
portb = f0
portc = e0
call delay
next k
return

'-------------------------------------------------------
RESET: PORTd.2 = 1 ;RESET 4017 pin 16-PIC
@NOP
PORTd.2 = 0
RETURN
'-----------------------------------------------------------
DELAY:
pause 1 ;
portb = 0 ; reset portb , c
portc = 0
portd.3 = 1 ; clock the 4017 pin17-PIC
@nop
portd.3 = 0

return
end


pokecode @$500, $2a,$55 ,$55, $2a ,$55 ,$2a ; store data in flash mem

thnaks for all reply,
