another possibility is that if using MPLAB that you haven't changed the 'build configuration' from 'debug' to 'release'. This must be done before you compile(F10), then download code into the PIC.

MCLR pulled up via 10K resistor and Vss are properly grounded. 0.1 micro farad disc capacitor is used for decoupling and Vdd voltage is +4.98V.

CCS compiler version - PCWHD 4.140

Thanks.

Hi,

I tried to do a LED blinking test using PIC18f252.

PIC18f252 with 8MHz crystal and 22pf capacitors. LED is connected to PORT A.1. Below is my coding.

#include <18F252.h>
