PICKitCMD-Pi

 

Overview

 

We call PICKitPlusCommandLine for the Raspberry Pi PICKitCMD-Pi.

 

PICKitCMD-Pi is the Raspberry Pi application that provides support for the latest generation of Microchip microcontrollers and EEPROMs devices.  The software is feature rich and easy to use via the console.

See below for supported Pi Hardware.

PICKitCMD-Pi application is the replacement application for existing Raspeberry Pi Python scripts as this is fully supported software.

The intent of PICKitCMD-Pi  is enable operations using either a PICKit 2 or PICKit 3 programmers via the Raspberry Pi Linux console interface.  Console arguments are passed to the software to configure the operation of write, reading, verify.  The software capabilities are shown in the table.

PICKitCMD-Pi supports nearly 1000 different types of microcontrollers and EEPROMS. 

  • PIC10F, PIC12F, PIC16F, PIC18F, PIC24.
  • dsPIC30 and dsPIC33 family.
  • A wide range of EEPROMs.
  • MCP2502X/5X & HCSxx.
  • EEPROM 11LCxx, 24LCxx, 25LCxx and 93LCxx, M25Px and FL127x.
  • See here for the full list of supported parts.

New functionality

  • Turbo mode - optimised write and read operations.
  • Manages Microchip HEF and SAF memory with automatically merge of HEF/SAF memory into target part.
  • New programming protocols to support for new classes of Microchips  microcontrollers.
  • Simple of command line arguments.
  • Part type, revision and family displayed during read operations.
  • Reset of Bandgap.
  • Updated and managed database for Microchip and other EEPROM devices.
  • Automatic programming of programmer firmware.

PICKitCMD-Pi features:

  • Supports the standard Microchip PICKit 2 and PICKit 3 programmer firmware.  PICKitPlus does not require an update to the Microchip PICKit 2 and PICKit 3 programmer firmware.
  • Supports multiple voltages within constraints of physical programmer - noting that some clone programmers do not support voltage control.
  • Read/write program and data memory of microcontroller.
  • Erase of program memory space with verification.
  • Supports IDEs with hold-on-exit.
  • Write/Read and Verify options.
  • Control power on and off independent of programming state.
  • OSCCAL support

Safe Usage Enhancements

  • Generation of log file.
  • Generation of error log file.
  • Internet connection not required.

 

Supported Pi Hardware

Raspberry Pi 4 is supported but the following constraint.  The Pi4 has a defect in its USB subsystem, which causes Microchip or clone PICKit 2 and PICKit 3 programmers to work poorly or not at all.   We provide a revised PICKit 2 programmer called PICKitPlus PI4 which resolves this issue. 

 

The PICKitPlus PI4 is a special variant programmer designed to work correctly on a Raspberry Pi 4.  It operate 4% slower than the standard  PICKitPlus model; but unlike the any PICKit2 or PICKIt3  the PICKitPlus programmer will function on a Pi 4.  The Raspberry Pi 4 USB subsystem has a subtle flaw that causes  PICKit2 or PICKIt3   programmer to "lock up" very frequently and need to be unplugged and replugged by hand.   Previous models of Raspberry Pi  and Raspberry 5 do not have this flaw.   The PICkitPlus PI4 solves this problem, and as a bonus also works everywhere a PK2 would.  Also, see here

Raspberry Pi 5 is fully supported using a Microchip or clone PICKit 2 and PICKit 3 programmer.
