Dear All experts
Now I am using PIC24FJ16GA002 with CCS C compiler (PCWHD). I have written a simple program Blink LED at port B1.
ON/OFF period is 1 ms. But the output that I got on oscilloscope is "3 ms" not as planned at 1 ms both of on and off.
I have connected 30MHz crystal at pin 9(OSCI) and pin 10(OSCO). Both of this pin have a 22 pF ceramic capacitor connected to the ground.
Below is my code. Could you please advise what I am wrong and which statement I should edit? Is it suspecting on FUSES configuration? :-(
