P89LPC935 Microcontroller Tutorial - gmitWEB

Generating Delays (1)
• Use a for loop
– Does not use any timer resources
– Uses CPU resources while running
• i.e. no other task can be performed during delay loop
– Can result in large amounts of machine code being generated
– Results may be different for different compilers
• The following code results in a half second delay for the P89LPC935
operating off the 7.373MHz RC oscillator
void delay()
{
unsigned int i;
for (i=0; i < 50000; i++);
}
