I have put these PIC chip pin out diagrams here as I am constantly referring to them and it takes ages to find where I put them on the PC. There are also some other common
You could just use the original description using GP1 etc but this doesn't give much useful information - but gives a very small space saving schematic symbol.
WARNING READ THE 12F675 1st BEFORE PROGRAMMING to get OSCCAL value out at location 3FFF hex.
This will save you having to
re-calibrate the internal oscillator.
(More info on the 12F675 page and here.)
(Calibration storage : tip for storing the calibration value )
The 16F84 is the most well known of the PIC micrcocontroller chips included here for reference as the it's getting a bit old now. (The 16F88 is a better choice for general project work and has the same pinout).
The 16F88 is largest chip used in the and has 18 pins. As there are more pins functions spread out amongst them so it's easier to use.
The 16F877A is the largest chip used (40 pins) in theprojects on this site and the pin functions are much more spread out. This makes it the easiest chip to use for designs as you can putcircuits on separate ports without having to think too much if you are going to need a different function later on.
Note: An equivalent chip is SP202ECP and it lets you use 100nF.
