pic16f84a probleem

[brand11]

pic ei taha siis k2ivituda ei mikroBasicu testprogega ega ka millegi muuga...

bas siis siin:
program Led_blinking

main:
TRISB = 0 ' configure pins of portb as output
PORTB = %11111111 ' turn ON diodes on portb
delay_ms(1000) ' wait for 1 second
PORTB = %00000000 ' turn OFF diodes on portb
delay_ms(1000) ' wait for 1 second
goto main ' endless loop
end
hex faili peale k6rvetades ei ilmne mingeid probleeme kuid toite taha lylitamisel led ainult p6leb...kas viga v6ib olla selles et pic ise vigane?

program LCD_demo

dim txt as char[17]

main:
PORTB = 0 ' intial value for portb
TRISB = 0 ' designate portb as output
Lcd_Init(PORTB) ' initialize LCD connected to portb
Lcd_Cmd(PORTB, LCD_CLEAR) ' send command to LCD "clear display"
LCD_Cmd(PORTB, LCD_CURSOR_OFF) ' send command cursor off
txt = "mikroElektronika" ' write string to txt
LCD_Out(PORTB,2,1,txt) ' print txt to LCD, 2nd row, 1st column
end.
kui panna row asemele 1 siis n2en millegip2rast ainult lcd 8 esimest m2rki ja kui panna row asemele 2 siis n2en 8 viimast m2rki...kas viga on lcd's?

panen siia ka asja asm faili...
asm fail

LCD ongi jaotatud mitmeks 8-märgiliseks osadispleiks. Pikema teksti puhul peab kogu aeg jälgima viimast pos.-i ja kui >8, peab saatma displeile käsu minna üle järgmisele reale (2x16 puhul reale 3) ja siis jälle datat saatma.

mälujaotus söltub jah lcd-st.
enamasti on see nii:

ma arvan et picbasicu soft toetab ka 1 realist LCDd, aga pead defineerima eelnevalt :
