    Just got my new Pickit 4. The initial evaluation is not good. I used Mplab X IPE (not IDE) for these tests.

    So far, I have only found one type of chip it will program- a PIC18F4685. The good news is that when it does program successfully it is really fast. I'd say nearly 10X faster than the Pickit 3. Tried nearly a dozen other chips. On most of them I get "Invalid device ID". I thought it must be something about the ICSP wiring, so I tried one of those adapter boards that just has a few sockets on it. Same results (but I CAN program all of the same chips using the SAME adapter board and a Pickit 2 or 3).
    Observations: When it is not connected the indicator is blue. When it is connected to a chip that it recognizes it turns red (why?). When programming is successful it remains red (why?).
    When I select some chip types, like PIC16F88, the ball next to the chip selection window is red and the "connect" button is greyed out. Why? the chip is listed as being supported.
    If it is set to provide power to the target it gets really warm after a few seconds.
    The SD card slot does not work yet. It will be supported in a future release.

    I'm really disappointed by this new programmer so far. I tried to be optimistic, but I kind of expected to be disappointed. Hopefully some of these issues will be resolved in upcoming firmware/ software releases.

    I'd be eager to hear from other users about their experiences with this device.

    The joys of being an early adopter Rick.
    When will companies wake up to the fact that red is a difficult colour for the 8% of men with a red/green colour deficiency. Yellow and blue would reduce the colour confusion by a large margin. At least the LEDs aren't green and red. Women are lucky they have the double X chromosome that reduces the odds of colour problems.
    Cheers

    Hi John-
    I'm only slightly red/green colorblind, but the big mystery for me is that there is an RGB LED in there, but I have never seen the green part illuminate.
    Call me crazy, but why not illuminate green when something good happens, and red when something bad happens?

    Furthermore, it's hard for me to imagine that Microchip would release a programmer that has trouble with PIC18F1220 PIC18F1320 PIC16F88 PIC18F4420 PIC24F08KL200, but I can program all of these with the PICKIT3. I've got to either have a bad Pickit 4 or I'm doing something stupid. Either of which is a possibility.

    Hi Rick,
    Sounds like a challenge. I wouldn't mind a spare for my trusty PICkit3 that's been in reliable use for many years. Perhaps I'll wait a while before 'updating'.
    It's absolutely a waste of time if it won't program the chips in your list.
    Might be time to dig a hole in the backyard and throw it in.
    Re the colour problem - it can be a pain. Small things are the main issue like resistor colour bands, the multimeter gets a good workout. No problem with traffic lights - I believe they put a bit of blue in the green to help. A red flag against green trees in the distance at a golf course is tough. I believe they used to have people with a colour deficiency as observers in aircraft during the war as they were better able to spot camouflaged tanks and stuff, or maybe people like me were more dispensable
    Good luck with the 4,
    John

    I just got mine too. Still feeling my way around.

    I select some chip types, like PIC16F88, the ball next to the chip selection window is red
    It's missing support for a number of chips, including the 16F88 you mentioned. That's what the red ball indicates.
    The ball will show yellow=preliminary support, green=full support, red=no support,

    There's a list in the file MPLABX/v4.15/docs/Device Support.htm

    When it is connected to a chip that it recognizes it turns red (why?). When programming is successful it remains red (why?)
    That's not what I observed.

    Selected an 18F87K22, power external:
    Target voltage detected
    Target device PIC18F87K22 found.
    Device Id Revision = 0x4
    - LED bar turned green

    Selected a 18F25K22, power from Pickit4:
    PICKit 4 is supplying power to the target (5.00 volts).
    Target device PIC18F25K22 found.
    Device Id Revision = 0x4
    - LED bar turned yellow


    If you go into advanced mode (Settings | Advanced mode) there are some tweaks for things like program speed etc.
    You'll find them using the advanced mode Settings button... scroll down and there's a 'pickit4 window'.
    Maybe try slowing it down?

    It is fast, I'll give it that. And it doesn't seem to download anything (other than the new firmware when I first ran the IPE).

    edit: I do have a problem getting it to recognize an 18F45K50, but I have a number of adapters to connect it to my target so maybe there's a problem there somewhere. Or maybe not...

    Mine was supposed to arrive last Friday but with the snow it didn't get here till Monday so I'll have to wait for the weekend to play with it properly.

    I did give it a quick run and it seems fine and it is incredibly fast, just a few seconds, I tried it with a 24FJ64GA004. First time using it did a firmware update which was automatic and just appeared as a text notification in the IPE window.

    My lights are blue when powered and green when connected in IPE, don't think I saw another colour.

    So far so good.......

    The MPLABX online help has descriptions of the LED bar meanings.

    Indicator Light Strip
    The expected start-up sequence for the MPLAB PICkit 4 debugger is:
    1. Purple - steady on for approximately 3 seconds
    2. Blue - flashing for approximately 2 seconds while the debugger runs a power-on self-test
    3. Blue - steady on. The debugger is ready.

    Additional Light Strip Descriptions
    Blue - Power is connected; debugger in standby
    Orange - Power target circuit from PICkit 4 checked
    Green - Power target circuit from PICkit 4 unchecked
    Purple - Bootloader is running
    Yellow - Debugger is busy
    Red - An operation has failed
    Purple - Fast blink indicates the time window for forcing the debugger into Bootloader mode

    What color is it supposed to be after successfully programming?
    The IPE says this:

    The following memory area(s) will be programmed:
    program memory: start address = 0x0, end address = 0x7bf

    In the image it looks almost orange, but looking at it directly I would say it's red.

    It doesn't seem to change color after it's successful, but then again I don't see it change to red when it fails, either. After powerup, for me it stays mostly green or yellow(orange?) depending on how I have target power set. It goes back to blue if I click 'Disconnect'.

    There's an LED brightness adjust on that 'pickit4' panel. Maybe futzing around with that will make the colors easier to distinguish.

    Bit worried my pickit3 might fail one day so being in a good mood as my PSA is still <0.03 and parts are freight free from MicrochipDirect this month I lashed out and bought a PICkit4.
    That may be a mistake. Some of you have had one for a few months now. Are they in constant use or in the cupboard?

    Mine has been very good, so far no problems but have only been using it for one project programming one particular 24 series chip, the speed is great.

    I have noticed that there are quite a few chips not yet supported including one I wanted to use, going back to the Pickit3 seemed very slow.

    Hi John- I think we're in the same boat. My PSA results just came back as .05, so all is good.

    As for the Pickit 4- It's under a pile of stuff in a drawer somewhere. I'm not going to bother with it any more until they support the SD card- then I might give it another try.

    Cool Re: New PICkit 4 available

    Hi guys!

    Today I received my PICkit4.
    Fingers crossed, but until now it works as it should and nice and fast.

    For those who also have PICkit4, here is how to work together with Proton IDE:

    If you received your PICkit4, do not connect it with your computer yet, first you have to install MPLABX v4.20 or later.


    First, you need minimal MPLABX version v4.20, older MPLABX versions will not work (good) with the PICkit4.
    Second, when you have downloaded MPLABX v4.20, you have enough to install only MPLAB IPE (and not the MPLAB IDE), if you only work with Proton PIC Basic.
    In MPLABX, as well the IPE as IDE are selected for installing, but why should you install a lot of data on your computer, if you don't use it?
    So unselect IDE if you not use this part.
    Just before installing has finished, it asked a few times if "software for this device should be installed" (which device is not mentioned, but always click YES)


    After installing MPLABX, you have a black and an orange logo on your desktop.
    Click the orange "MPLABX IPE v4.20"
    Now, connect the PICkit4 programmer on your computer.
    It will take several minutes before PICkit4 has installed.


    If the PICkit4 is installed, then it would be recognized and it would be showed after "Tool:"
    Try if you can program a PIC with MPLABX IPE.
    Select first the PIC device (type)
    Then browse to a HEX file you have created earlier (with i.e. Proton).
    Finally click on 'Program'.



    CONNECT WITH PROTON IDE:

    Then, in the Proton IDE (don't confuse it with MPLAB IDE):
    Click: View > Compile and Program Options... >
    Select tab: Programmer
    Click: Install New Programmer...
    Select: Create a custom programmer entry
    Enter Display Name: PICkit4 - Target supply
    Programmer Filename: ipecmd.exe
    Find Manually: Windows(C : > Program Files (x86) > Microchip > MPLABX > v4.20 > mplab_platform > mplab_ipe
    Parameters: /P$target-device$ /F"$hex-filename$" /TPPK4 /M /OL
    Click: Finished


    The parameters above are for use when the power comes from the target PIC (this is a safe method if you regularly use 3,3V as well as 5V devices)


    If you want the power from out the PICkit4, then the parameters are:

    For 3,3V
    /P$target-device$ /F"$hex-filename$" /TPPK4 /M /OL /W3.3

    For 5V
    /P$target-device$ /F"$hex-filename$" /TPPK4 /M /OL /W5


    It is possible that your computer does not provide sufficient voltage on the USB to program the PIC with 5V.
    You will then get programming errors.
    Then set the voltage a bit lower, for example at 4.5V.
    /P$target-device$ /F"$hex-filename$" /TPPK4 /M /OL /W4.5

    (Another reason to program with the target power and the first mentioned parameters)


    Good luck!
    Frizie.

    Would you please make a WIKI article, perhaps in the hints section? Your description is too useful to have disappear into the depths of the forum.
