I have done right?

- - - Updated - - -

please If it's just how I am introduced or call later in my program

what hardware are you using ?
LCD + 74164 or 74595 ? , 7 segment led display + 74XXXX ?
or other ?

you define MACRO to simply the writing of code, so use it ..

.....


LCDUpdate                  ; entry of the subroutine
        movlw 8                
    movwf Counter
SerialLoop
    rrf LCD_Data,f        
    btfss STATUS,C        
    goto SendLow
    bsf D_Data            
    goto SendClock
SendLow
    bcf D_Data            
SendClock
    STROBE            
    decfsz Counter,f    
    goto SerialLoop
        return                   ; <- return  to main program


      and use it as subroutine
       in the main loop program


       movf Beaufort,W     ; your value to display  0<= value <=9
       addlw 0x30;          // or Addlw '0' to transform in ascii '0' to '9'
       movwf LCDData
       call LCDUpdate

nota : i suppose the software is adapted to your hardware .. not sure !


Display on LCD + 74HC164, uses 2 wires
MPLAB ASM PIC12F683 .. for real test .. Ok
View attachment 12F683_LCD_2w_74164.zip

running:
1rst line .. just display values from 0 to 9
2nd line : incremental counter value from 0 to 255
then ADC value 0 to 255
then Beaufort value 0 to 9
refresh every 1 seconde using timer0
all delay made by timer0.

 

[paulfjujo]

hello,

Software compiled with MPLAB 8.92 MPASM.. OK
use 15 bytes of RAM
Not tested in real world .. because no PIC component at disposal.
Tested with a 12F683..OK



Hardware :
tested with 12F683 ..not with 10F220

[betwixt]

paulfjujo, it has to be an LCD and 10F220 which only has 6 pins in total! VSS,VDD, one digital input, one analog input and two bidirectional I/O.

Thierry has so far proved they can copy and paste but made no effort to do any coding or decide on the type of interface the want to use.
