hello..

I have written 2 code using MPLAB C30 compiler and MikroC dsPIC compiler for dsPIC30F6014A..

two codes are like below..

In MPLAB C30>>

PORTDbits.RD1 = 1;
PORTDbits.RD1 = 0;
PORTDbits.RD2 = 1;


In MikroC >>

const char ONE = 1;
const char TWO = 2;

PORTD.ONE = 1;
PORTD.ONE = 0;
PORTD.TWO = 1;

I expected the same result form both codes.. But results as follows..

In MPLAB C30>> PORTD 1st bit(RD1) set as 1 (but i'm expecting 0) 8-O

In MikroC >> PORTD 1st bit(RD1) set as 0

Can anyone explain this???????


And after inserted a delay to MPLAB C30 code it gave the correct results as mikroC code (PORTD 1st bit(RD1) set as 0) ... :-D

like this>>

PORTDbits.RD1 = 1;
delay(10);
PORTDbits.RD1 = 0;
delay(10);
PORTDbits.RD2 = 1;

Is this happened due to PORTD register writing delay???????? can't believe it...!!!!!
