Help with code, settings

[xobx]

I cant get this code to work with my PIC16F887 :/

@   device  pic16F887, hs_osc, wdt_off, mclr_on, lvp_off, protect_off
DEFINE OSC 20

loop: 

high portb.2
pause 500
low portb.2
pause 500
goto loop
end

Im not 100% sure if this is right, is it?

@   device  pic16F887, hs_osc, wdt_off, mclr_on, lvp_off, protect_off

If you are are using MPSAM and you have the correct chip selected in MCS then try

@ __CONFIG _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _BODEN_ON

and then add then line

DEFINE OSC 20

See if that works

is it not compiling correctly or is it that portb.2 isn't toggling in your circuit?

if it's that it's not working in your circuit, it could be a couple of things; no pull-up resistor on MCLR, oscillator not correct or not functioning correctly (capacitors), RB.2 not set to digital or not set to an output

Cheers

For PM assembler use:

@ DEVICE  PIC16F887, HS_OSC
@ DEVICE  PIC16F887, WDT_OFF
@ DEVICE  PIC16F887, MCLR_ON
@ DEVICE  PIC16F887, LVP_OFF
@ DEVICE  PIC16F887, PROTECT_OFF

For MPASM use:

@ __config _HS_OSC & _WDT_OFF & _PWRTE_ON & _LVP_OFF & MCLR_ON, & PROTECT_OFF

If you are using a bootloader you need something like

DEFINE Loader_Used 1


near the top of your program
