    Usually the baud is at 9600 by default.

    Also USB to Serial converters may pose an issue sometimes.

    Default size of hex file

    When i compile my code i generate HEX file of 3KB which cant fit PIC16F84, since its limit is 1KB is there a way i can compress it and load it into pic16f84

    I never use simulators of any kind. And Never ever write the whole program at once. I am not Darrel or Melanie...

    What I do is:

    1. Whenever I change PIC, I start by a led and a button. Just 3 lines of code to read the button and light the LED.

    2. Then I add a serial port to see on a terminal what is happening to the PIC.

    3. Then an LCD and see if it works.

    4. Then...
