#162465 - Supplementary question... Responding to: ???'s previous message |
As a supplementary question for extra points, consider the effect of changing
From:
for ( i = 0; i < 1000; i++)
{
P1_0 = 0; //OFF
P1_0 = 1; //ON
}
To:
for ( i = 1000; i > 0; i-- )
{
P1_0 = 0; //OFF
P1_0 = 1; //ON
}
Also, investigate the effect(s) of different compiler optimisations... |
