Hi all,
I am new to this forum but not new to micros - just PICS. All previous experience was with the Parallax stamp but they are simply too expensive.
So a basic question about connecting two PIC 18X chips together. Pic 1 will be an infrared receiver and will place values it receives from the remote on its outputs 0 - 6. Pic two will read those data lines after it gets a data strobe using an interrupt.
Question 1
My basic question is: Can I directly connect the pins of PIC 1 to PIC 2 without any pull up/down resistors or current limiters?
Question 2:
Do unused I/O pins need to be pulled up/down or can they float?
Thanks
