i am using the PWM feature of the PIC 16f877a to generate a 36KHz carrier wave with 25% duty cycle for one of my ir remote control projects.
I wrote a code for the above purpose in the MPLAB IDE v7.50... before building the program i have to set configuration bits...
in this, there are 4 options (RC, LP, XT and HS) under OSCILLATOR... what option must i choose and why? I am sure its not RC oscillator.
Note that i will be building the circuit on a protoboard congiguring the PIC to transmit IR codes. What kind of external oscillator must i choose?
