Propeller 2

Parallax Propeller II MCU

OBEX (Object Exchange)
- There's a new OBEX in 2023, find it here
- OBEX has now moved to github. Find it here.
- OBEX has been a valuable resource for P1. Hopefully, will continute to be for P2 as more code becomes available.

Display large images over VGA using Color Cell Compression
- P2 code and Compression Tool are here.

MicroPython and RiscvP2
- MicroPython Binaries for P2 and info on how to build it is here.

Use free Visual Studio Community edition to edit Flex C code!
- This is my current favorite way to program the P2
- Here's How

Compilers
- FlexProp (was FlexSpin) is a compiler for both Spin1 and Spin2 and also does a version of Basic and C
  - Compiles to Hubexec and uses absolute addressing
  - Open Source
  - Can download from the github page here or with the GUI link below
  - Official GUI is called FlexGui and is available here.
  - My Usage notes for FlexProp
- PNut is a basic GUI and compiler for Spin2 by Parallax
  - Compiles to Cogexec and uses relative addressing
  - Propeller Tool 2 GUI is in development, currently works a lot like the original
  - Get the latest from propeller.parallax.com
- Catalina is an ANSI complient C compiler for both Spin1 and Spin2 (Now with Geany IDE). Available here.
- Clang/LLVM Is a new C++ compiler for P2 and appears to be working as of 19Feb22

Programming Notes
- Click here for Tricks & Traps
- Porting P1 code to P2
- Every I/O pin can be used to create an NCO square wave using it's smartpin

GUI
- The Propeller Tool now supports P2
- FlexGui is the official GUI for fastspin and is available here.
- SpinEdit GUI (see below) can work with both Fastspin and PNut, was meant to fill the void until the Propeller Tool came

Propeller Code Generator
- This is a program to automatically generate and run example C code with customization.
- Get it in the Forum here.
- There's a Spin2 version in the works here

SpinEdit
- SpinEdit isn't really used or supported much now that the new Propeller Tool is out...
- An editor for Spin2 (and Spin1) files. Find info and the latest version in the end of this forum thread. Or, download direct from here.
- Spin2 now works with both PNut and Fastspin (PNut integration is rather basic though as PNut doesn't provide compile info to command line).
- Also provides support for FlexBasic and FlexC as well as Spin1.
- Known Issues:
  - Flow indicators don't always work right for complex, nested loop structures.
  - Syntax highlighting is mostly correct, but a couple rarely used things don't get highlighted properly.

Example code for Eval board (and sometimes works on FPGA)
- USB Keyboard and Mouse by garryj, now uses just one cog
- 90's style 3D Graphics by (Rayman (me))
- uSD Video Player for P2 (by Rayman)
- HyperRam & HyperFlash examples (by Rayman)

Production History:
- Rev.B of the silicon was for sale ~ Nov. 8, 2019
- Rev.C (final version) arrived in June 2020
