GPS Project: PIC18F26K22 or PIC18F46K22

[astanapane]

First Question is: How do we select the PIC, and why did we select this particular one (PIC18F26K22) for a number of examples in this project.

The Datasheet is very important to have it as a reference all the time.

I will answer as a newbie and hopefully the experienced programmers and users will help to correct me or add useful additional information.

In most of the new basic projects, we need to add components in our circuit that require more ports to be in use, specific features, High CPU SPEED and SPACE in RAM....... For example, in this final project, we will use a variety of components like:

1. Display
2. GPS Module, (GSM 2G-SIM module, this will be added at the end)
3. SD card

Each of the components required to have a dedicated port on the PIC and a specific protocol to communicate with.

For example we need to identifyfor each component, how it works and what communication protocol needs to be connected with the PIC!!!

A Display and the SD that has the SPI or I2C option to communicate , needs to be connected with a PIC that features these peripherals.
