Help to choose PIC device

Hello!
I am completely new in microchip world. I want to learn PIC micro-controller for electric power measurement, Smart Grid, Power system Protection, Internet of the things etc.

Will it better to use PIC18F87K22 device?

    No. Every application you listed has its own dedicated or at least optimal core/frontend device(s).

    If i was going to make somthing like that i think i first of all select something with Ethernet contollers built in to it from start.
    So i compiled a list from digikey.com of parts, tho i have never bought from digikey, they are just too expensive and i have had no success negotiating prices with them.
    Here is the list:
    The list disappered.

    Are you using a development boards or you are going to start on a beeadboard? I'll suggest to start with a development boards with which can support those features you want to study such as sensors, communication, then start with the PIC supplied with the board. Don't get overwhelmed by so many features, start small with simple stuff one thing at a time.

    None of the devices (MCUs) you listed are special tailored for any of the purposes the OP mentioned above. Moreover, most of the devices you listed are not PIC devices at all and especially 8-bit PIC devices this forum is dedicated to.

    Hi,
    PIC18F87K22 is a very big device for a microcontroller.
    With 80 pins with 0.5 mm spacing, are you sure that you are able to use it?
    Are you going to design a Board yourself,
    or have you identified a Development Board with the device already mounted?
     
    For Learning and initial development, a smaller device in the same family may make more sense.
    While a Development board may be more expensive than a loose microcontroller device,
    designing and producing a board for a 80 pin MCU is more timeconsuming and expensive,
    with much more risk of failure.
     
    My suggestion for learning and initial development, might be a Curiosity HPC development board DM164136
    https://www.microchip.com...roductDetails/dm164136
    It may be used with PIC18F26K22 in 28 pin PDIP package or PIC18F46K22 in 40 pin PDIP package.
    or any modern PIC16 or PIC18 in 28 pin or 40 pin PDIP package,
    e.g PIC18F46K40 or PIC18F27K42 or PIC18F47K42.
    All of these devices have the same CPU, and mostly the same peripherals,
    so you may learn and develop code that may be used in other devices in the family.
     
    Another possibility would be MPLAB Xpress board: DM182026
    https://www.microchip.com...roductDetails/dm182026
    with PIC18F46K42.

    No they are not ALL pic devices, but they are ALL sold by Microchip, as such i bet there are development tools for them supplied by Microchip.
     
    I selected those because of the desire from the thread creator to do "internet of things", i found it better to help the thread creator by showing a list of processors that can handle ethernet than be that strict and ONLY recommend 8 bit microcontrollers.

    If you want Wi-Fi, I would go with something like dsPIC33EP .. GS and an external Wi-Fi such as ESP2866, but it all depends on details.

    Actually the OP never actually states an explicit desire to use only an 8-bit device, simply starts off with a specific 8-bit device named in the post -  PIC18F87K22.
    Lots of non 8-bit posts in this forum.......

    OP posted here. That's pretty explicit.

    Lots of idiots, too.
    But we should start with the assumption OP is not, and wait to be proven wrong.

    Internet of Things was just one of the application areas listed. What about all of the others?
     
    and
     
    Internet does not equal Ethernet. You can do either without the other.

    Yes it seems reasonable that even if the OP had stated a specific desire to use an 8-bit device it is NOT unreasonable to mention other devices (not 8-bit) that may either actually achieve the desired results or are more applicable then an 8-bit device. IF the OP had stated it MUST be an 8-bit device and that is not possible/likely then would we jump on anyone who offers non 8-bit alternatives? I would hope not.

    Hi,
    Original poster admit to be new in microchip environment,
    and do not state what other experience he may have.
     
    Learning is a gradual process, and my suggestion is to proceed in small steps.
    Some of the application areas suggested in message #1 may most suitably be performed by use of frontend sensors, like specialized energy meter chips, and external Ethernet controller or Wi-Fi radio.
    Such devices may reasonably be tied together by a 8 bit microcontroller,
    and a PIC18F device in the K22 family is a reasonable choice, in my opinion.
     
    With a Curiosity board, it may be possible to find some Click boards from Mikro Elektronika, for some of the external interfaces.
     
    There may be many other alternative, but they become no less complicated.

    Your range of interest is so broad that no specific Microchip device can encompass all of them.
     
    If you describe a simpler, focused, short term goal more useful suggestions can be made.
     
    Microchip sells development boards for the areas you've expressed an interest in, so buy one of each and work through the examples in the user's guide.

    Especially when you are new, you can't realistically expect to start leaning by focusing on all those applications. Get a cheap Curiosity board or something better if you can afford if you don't have one yet. The curiosity has a click interface for external modules, start with simple projects, then broaden your horizons.
