  • Page 6: Introduction

    1. Introduction The Rabbit 2000 a a new and powerful microprocessor. Both hardware and software design are easy with the Rabbit. This kit has the essentials that you need to design your own a microprocessor-based sys- tem, and includes a complete software development system (Dynamic C). This Develop- ment Kit contains a powerful single-board computer (the Jackrabbit board).

  • Page 7: An Overview Of Dynamic C For The Rabbit

    1.3 An Overview of Dynamic C for the Rabbit The Rabbit 2000 is programmed using Z-World’s Dynamic C, an integrated development environment that includes an editor, a C compiler, and a debugger. Library functions pro- vide an easy-to-use interface for the Jackrabbit board included with the Development Kit.
  • Page 8 You have a choice of doing your software development in the flash memory or in the static RAM included on the Jackrabbit board. There are 128K in each memory. Versions of the Jackrabbit board are available that support only 32K of static RAM. If you use one of these boards, you must do development in flash memory.

    2. Detailed Installation Instructions Chapter 2 contains detailed instructions for installing the software on your PC and for con- necting the Jackrabbit board to your PC in order to run sample programs. 2.1 Software Installation You will need approximately 10 megabytes of free space on your hard disk. The software can be installed on your C drive or any other convenient drive.

    • Setting break points. The key is used to turn on or turn off (toggle) a break point at the cursor position if the program has already been compiled. You can set a break point if the program is paused at a break point. You can also set a break point in a program that is running at full speed.

    The statement at (3) waits for a time delay, in this case 200 ms. The costatement is being executed on each pass through the big loop. When a condition is encountered waitfor the first time, the current value of is saved and then on each subsequent pass MS_TIMER the saved value is compared to the current value.

    Rabbit programming interface. This is a 10-pin connector that connects to the Rabbit serial port A. It is possible to reset and cold-boot a Rabbit processor via the programming port. No software needs to be present in the target system.

    In this situation, the hardware real-time clock can be read directly to provide the time. • Watchdog support routines. Although the Rabbit watchdog can be disabled, this is not recommended since the watchdog is an essential facility for recovering from crashes.

  • Page 24: Analog Output

    void digOut(int channel, int value) sets the state of a digital output bit. jrioInit must be called first. channel is the output channel number (0-3 on the Jackrabbit). value is the output value (0 or 1). void digOn(int channel) sets the state of a digital output bit to on (1). jrioInit must be called first.

    – -------------------------------------------------------------------- - PWM_MAX0 PWM_MIN – × – m PWM_MAX0 × voltage m value 4.2.4 Analog Input The analog input channel on the Jackrabbit (AD0 on header J5) works by varying analog output channel DA0 until its voltage matches the input voltage on AD0. DA0 obviously cannot be used while an input voltage is being measured, although channel DA0 is still available.

  • Page 28: Non-Cofunction Blocking Input Functions

    4.3.2 Non-Cofunction Blocking Input Functions These are simple functions that do not use Dynamic C costatements. If no input data are available when called, they return immediately with appropriate status information in their return value. Once they begin to receive characters, they do not yield to other tasks until they complete their operation or until a character-to-character timeout period elapses.

  • Page 29: Non-Cofunction Blocking Output Functions

    Parameters data —Destination data structure. The user must ensure data is allocated for at least length bytes. length —The number of bytes to read. Return Value The number of bytes written to the serial port. Rabbit 2000 Development Kit...

  • Page 30: Single-User Cofunction Input Functions

    4.3.4 Single-User Cofunction Input Functions These are Dynamic C cofunctions. If the input buffer they use is locked or becomes full during the course of their operation, they yield to other tasks, but do not return to execute the next statement within their own costatement block until they have completed their operation. scofunc int cof_serXgetc ( );...

    Writes a block of characters to the serial port, yielding to other tasks when unsuccessful or whenever the buffer is full, returning only when all the data is successfully written.

  • Page 32: Circular Buffer Functions

    4.3.6 Circular Buffer Functions These functions act on or report status of the circular transmit/receive buffers. Macro definitions are used to establish the buffer sizes: xINBUFSIZE —read buffer size, where is A, B, C, or D xOUTBUFSIZE —write buffer size where is A, B, C, or D The user must define each buffer size for each port being used to be a power of 2 minus 1 with a macro.
