The hub allows access to each of the cogs in a round-robin fashion at a clock rate that is half the rate of the system clock. Detailed descriptions of the best- and worst-case scenarios for the interaction of the hub with the cogs, along with timing diagrams, are provided in the Propeller Manual. All 32 I/O pins can be used for I/O when the system is not using pins 28 to 31 for serial interfacing and/or external memory access. Each of the 32 pins can be made into either an input or output. If made into an output, each of the pins can be set either high or low. When designated as an input, the pin assumes a high impedance state and awaits input from the outside. Because each of the cogs can access all the I/O pins at all times, there is a need for an I/O sharing protocol that keeps things under control. You should become familiar with this protocol before designing complicated schemes for accessing the I/O pins with more than one cog. For our immediate purposes, however, this can be ignored. A family of eight lock bits is provided by the system to prevent errors when more than one cog is accessing common resources. Conditions can exist such that one cog is writing to a memory location when another cog is reading from that same location. The system of locks enables you to lock down and release the system while you undertake certain critical read/write operations (on more than one 32-bit long). The chip has 64KB total of shared (main) memory that can be accessed by all the cogs on a mutually exclusive basis, as controlled by the hub. Of this, 32KB is in the form of RAM and 32KB is in the form of ROM. The main RAM is used by the Propeller to store the application we write, along with data, variables, and stack space to perform specified operations. The other half of the main memory, the ROM, contains the font character definitions and the sine and log tables used for writing to display devices and for creating the math functions needed by any application. Main ROM also contains the boot loader, which is used upon startup. The Spin interpreter is also stored here, and it gets copied to each cog RAM, from where it fetches, interprets, and executes Spin code tokens from main RAM.

The Propeller Tool is a software-writing environment suitable for creating programs in Spin and Propeller Assembly. It is designed for use on an IBM (or Windows/Intel) compatible personal computer. (The software is not available for the Apple Macintosh at this time.) The Propeller Tool is connected to the Propeller hardware environment most conveniently through a prop plug, an inexpensive USB to serial port converter available from Parallax. (If you like, you can make your own converter; a circuit is provided in Propeller Help.) Downloading the programs to the Propeller chip and then executing them is a one-keypress proposition. Parallax provides a special font (called the Parallax font) for writing programs for the Propeller chip. This font is resident in the chip s main ROM and is to be used in

video displays. It is also included in the Propeller Tool as a TrueType font that is installed on the programmer s PC and used by the Propeller Tool. The font is divided into two parts: one for writing programs and the other for creating the wiring diagrams needed to document the effort being undertaken. Special features of the software environment allow extensive documentation to be embedded in the program being written at two levels. Each level of the documentation can be suppressed and made visible as needed. Because this can be done at two levels, minimal documentation can be separated from extensive documentation, and either one or both can be suppressed or made visible as needed by a programmer or user. There is no particular point in going over the details of the operation of the Propeller Tool. You should refer to the Propeller Tool s Help section for these details. At the time of this writing, the current version of the Propeller Tool is version 1.2.6. The Propeller Tool environment is a very powerful and easy-to-use environment that allows you to have any number of programs open at any one time, limited only by the memory you have available in your personal computer. Having multiple programs open at the same time allows cutting and pasting between programs and speeds up the writing and documentation of programs. Among other things, it allows you to jump back and forth between programs with one click and execute the program with another. This, in turn, allows you to make modifications to programs and run either version to see the changes painlessly. Very ingenious, very powerful.
