Hello, I've been trying to burn a simple "Blinking LED" program on the AT89LP6440 MCU with no luck. I am using Keil Uvision 4.0, and there are no compilation errors or warning for the code below:
#include <AT89LP6440.H> sbit led = P2^0; void delay(long i) { for(i=0;i<i;i++); } void main() { while(1) { led=1; delay(20000); led=0; delay(20000); } }
Am i missing anything? The multimeter shows that P2_0 just stays HIGH (5 Volts). Thanks, Ben
I've changed the code to this:
#include <AT89LP6440.H> sbit led = P2^0; void delay(int num) { int i; for(i=0;i<num;i++); } void main() { while(1) { led=1; delay(20000); led=0; delay(20000); } }
Still no results. Maybe I'm missing an I\O configuration?
how is your LED connected? is the LED on or off? how do you 'burn' the code?
