Hello Sir,
Currently, we are using Tower System TWR-S08PT60. In the default mode of clock operation(bus clock is derived from Internal reference clock), we have following questions/issues
- Is it necessary to give a delay before any peripheral initialization,which is performed after reset? If so, Kindly let us know the procedure
- We are trying to toggle a GPIO Pin( PTG0) with a certain delay for both Ton and Toff
In the following program, it is observed that duty cycle is increasing for increasing values of x with x>=1000.Kindly let us the know the reason
void delay_ms(unsigned int x)
{
unsigned int i,j;
for(i=0;i<x;i++)
asm
{
NOP;
}
}
void main()
{
PORT_PTGOE_PTGOE0=1; // configuring Port G0 as output
while(1)
{
PORT_PTGD_PTGD0=0; //Turns on LED
delay_ms(1000);
PORT_PTGD_PTGD0=1; //Turns off LED
delay_ms(1000);
}
}
Thanks & Regards,
Raghavendra T R
