2024-12 I scrapped my PICKIT 2 and PICKIT 3. (They are no longer supported anyway!) Currently I have a PICKIT 5 ($95) and a SNAP ($15).

PICKIT 5 -- Works with VS Code. YAY. JTAG (ARM or AVR), SWD, ICSP, AVR. It also slices and dices. USB-C connector There is an adapter that turns it into a Segger J-Link. Sounds like the Nordic DK, there seems to be no reason to buy a Segger! :-) Target Connection Pinouts

SNAP -- Looks suspiciously like a PICKIT 5 without the box. Hmmm. USB Micro connector

There is a comparison chart on this page. PICKIT 5 is better.

The chips

What I have around right now

  • PIC 18F25K20 (28 pin) compares well with the chip used for Arduino, the ATmega328p
  • PIC 16F873 (28 pin) pin compatible with the 18F25K20, but requires an external clock
  • PIC 16F628 (20 pin)
  • PIC 12F675 (8 pin)
  • PIC 12F629 (8 pin)
  • PIC 12F683 (8 pin)
  • PIC 12F1501 (8 pin)
  • PIC 10F322 (8 pin DIP, also available in 6 pin SOIC)
  • 24LC65 8Kx8 EEPROM
  • 8 MHz ceramic resonators
  • 4 MHz ceramic resonators
  • 32kHz xtals for slow but very low power operation (button cell powered data collectors)

Development tools

Hardware

The older PICKITs came with a 18F* dev board, and a 10F322 board and a protoboard.

MpLabX IDE

MPLAB X downloads

2024-DEC-03 6.20 on Murre (Mint) Download is packed as a shell script in a tar file. Installation was easy. Everything installed into /opt/microchip.

I installed all the compilers (xc8, xc-dsc, xc16, xc32).

The "extras" have to be installed separately.

Code Configurator is here: http://www.microchip.com/mplab/mplab-code-configurator

There are also libraries.

They have a thing called "Harmony" that I have not looked at because it's for PIC32

Eagle CAD

Use the SparkFun library from https://github.com/sparkfun/SparkFun-Eagle-Libraries

High Level Languages

C language

MPLAB XC: mostly free C compilers http://www.microchip.com/pagehandler/en_us/devtools/mplabxc/Non-free options offer better optimizations. You get a 60 day eval on PRO level with the free version.

http://www.ccsinfo.com/picc.shtml C compilers starting at just $50.
