DFP Manager

CLI tool to manage Microchip's Device Family Packs.

This tool downloads CMSIS-Packs from Microchip Packs Repository and extracts them to a central install directory located (default ~/.mchp_packs). It also implements a search function that allows you to find which pack contains a specific device.

A wrapper around xc8-cc allows you to instatiate with just the -mcpu flag, automatically searching for the correct device pack and injecting the -mdfp flag into the command.

Usage:
  dfpm [-p <path>] install <pack>
  dfpm [-p <path>] list
  dfpm [-p <path>] search [-d] <string>
  dfpm [-p <path>] xc8 [-mcpu=<cpu_id>] [<argument>...]

Options:
  -p <path>, --pack-dir <path>  specify pack directory to use [default: ~/.mchp_packs]
  -d, --download                automatically download packs
  -h, --help                    print help and exit
  --version                     print version and exit

Examples

Example 1: Installing device pack for PIC16F1xxxx devices

$ dfpm install Microchip.PIC16F1xxxx_DFP.1.31.465.atpack

Example 2: Searching for and installing device pack containing the pic16lf19197 device
