I created a sample project in Atmel Studio 7, and tried to run it using the simulator. Although I saw a status of running at the bottom of the screen, after a few clicks on step into I can saw that portc is being updated. But the button is not active any more. The Memory4 window had a message of "Unavailable when debuggee is running." I have enclosed screen captures of what I saw. The code was:
#define F_CPU 16000000UL
#include <avr/io.h>
#include "util/delay.h"
void Wait()
{
uint8_t i=0;
for (;i<23;i++)
_delay_loop_2(0);
}
int main(void)
{
/* Set PORTC0 as output */
DDRC=0b0000001;
while (1)
{
//Set PC0=High (+5v)
PORTC= 0b0000001;
Wait();
//Set PC0=Low(GND)
PORTC&=0b1111110;
Wait();
}
}
I am new to Atmel Studio, and I thought by using the simulator I would see an interface similar to Android Emulator which presents a visual pic of your code's outcome. In my case, I configured a ATmega32 target board.
So my question is basically how can I continue the debug session until I stop it myself; i.e. how do I get rid of the error message stated above and what does it mean?
