Hello,
I use the MC908GZ60 and the CodeWarrior IDE version 5.7.0
I just want all Ports A...G define as output. And switch them to 1.
Therfore I wrote this code:
#include <hidef.h> /* for EnableInterrupts macro */
#include "derivative.h" /* include peripheral declarations */
void main(void) {
EnableInterrupts; /* enable interrupts */
/* include your code here */
PTA = 0xFF;
PTB = 0xFF;
PTC = 0xFF;
PTD = 0xFF;
PTE = 0xFF;
PTF = 0xFF;
PTG = 0xFF;
DDRA = 0xFF;
DDRB = 0xFF;
DDRC = 0xFF;
DDRD = 0xFF;
DDRE = 0xFF;
DDRF = 0xFF;
DDRG = 0xFF;
for(;
{
__RESET_WATCHDOG(); /* feeds the dog */
} /* loop forever */
/* please make sure that you never leave main */
}
But it doesnt work.
If i do single steps until line "DDRA = 0xFF;" nothing happens in Data1 window. The next step changes _PTA and _PTE into 63 (0b00111111)
Why this?
If i insert after the line DDRG = 0xFF;
this: PTA = 0xFF;
PTA changes into 255.
Thanks for all answers!
