I never use PT2272. I just now see the schematic, the only pin PT2272 connect to PIC is ADC pin. Then you converting PIC16 to PIC18. You must get the digital i/o to function also need to get the ADC function.

Alternative, you can by pass to use PT2272 by connect directly to PIC UART ex Low Cost RF Module and RF Remote.

The hardware connection, can't check only by photo. Need to check by multimeter that the only you can do it and tell either it's right or wrong.

For me, it's simple. If you understand, it becomes simple.
