Device-independent networking protocols for the P8X32A/Propeller, P2X8C4M64P/Propeller 2

network-spin

---

This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 networking stack

IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.

Salient Features

• Ethernet II
• IP
• ARP
• UDP
• TCP
• ICMP
• BOOTP/DHCP
• Socket manager (TCP, single socket)

Requirements

P1/SPIN1:

• spin-standard-library
• an object (e.g., network device driver) that provides FIFO R/W methods

P2/SPIN2:

• p2-spin-standard-library
• an object (e.g., network device driver) that provides FIFO R/W methods

Compiler Compatibility

Processor	Language	Compiler	Backend	Status
P1	SPIN1	FlexSpin (6.5.0-beta)	Bytecode	OK
P1	SPIN1	FlexSpin (6.5.0-beta)	Native code	OK
P2	SPIN2	FlexSpin (6.5.0-beta)	NuCode	OK
P2	SPIN2	FlexSpin (6.5.0-beta)	Native code	Untested

(other versions or toolchains not listed are not supported, and may or may not work)

Limitations

• Very early in development - may malfunction, or outright fail to build
• Some things are currently hardcoded
• API unstable (only one network device driver currently exists)
• IP only really supports 20-byte headers
• ICMP is currently very primitive - only enough is implemented to store/retrieve metadata and is written with enough to form reply messages to echo requests.
