Rabbit 2000 microprocessor. It does not contain detailed information on the hardware capabilities or the Dynamic C development environment. Most users will want more detailed information on some or all of these topics in order to put the Rabbit 2000 microprocessor to effective use. -
Page 7: Using Online Documentation
1.3.3 Using Online Documentation We provide the bulk of our user and reference documentation in two electronic formats, HTML and Adobe PDF. We do this for several reasons. We believe that providing all users with our complete library of product and reference manuals is a useful convenience. -
Page 8: Ce Compliance
The Jackrabbit series of single-board computers meets the following emission standards with the Rabbit 2000 spectrum spreader turned on and set to the normal mode. The spec- trum spreader is only available with Rev. C or higher of the Rabbit 2000 microprocessor. -
Page 9: Spectrum Spreader
Rabbit 2000 Development Kit. 1.4.1 Spectrum Spreader Jackrabbit boards that carry the CE mark have a Rabbit 2000 microprocessor that features a spectrum spreader, which helps to mitigate EMI problems. By default, the spectrum spreader is on automatically for Jackrabbit BL1810 boards that carry the CE mark when used with Dynamic C 7.32 or later versions so as to maintain CE compliance, but the spec-... -

Page 11: Chapter 2. Detailed Installation Instructions
2. D ETAILED NSTALLATION NSTRUCTIONS Chapter 2 contains detailed instructions for installing the soft- ware on your PC and for connecting the Jackrabbit board to your PC in order to run sample programs. 2.1 Software Installation You will need approximately 200 megabytes of free space on your hard disk for a com- plete installation. -
Page 12: Prototyping Board
The Prototyping Board included in the Development Kit makes it easy to connect a Jack- rabbit board to a power supply and a PC workstation for development. It also provides some basic I/O peripherals (switches and LEDs), as well as a prototyping area for more advanced hardware development. -
Page 13: Prototyping Board Features
PB2–PB5 pins of the Rabbit 2000 microprocessor on the Jackrabbit, and may be read as inputs by sample applications. Four LEDs are connected to the PA1–PA4 pins of the of the Rabbit 2000 microproces- sor on the Jackrabbit, and may be driven as output indicators by sample applications. -
Page 14: Development Hardware Connections
There are four steps to connecting the Prototyping Board for use with Dynamic C and the sample programs: 1. Attach the Jackrabbit to the Prototyping Board. 2. Connect the programming cable between the Jackrabbit and the workstation PC. 3. Connect the power supply to the Jackrabbit. Rabbit 2000 Development Kit... -
Page 15: Attach Jackrabbit To Prototyping Board
2.3.1 Attach Jackrabbit to Prototyping Board To attach the Jackrabbit board to the Prototyping Board, turn the Jackrabbit board over so that the battery is facing up. Plug headers J4 and J5 into the sockets at J2 and J6 on the Prototyping Board as indicated in Figure 2. -
Page 16: Connect Programming Cable
NOTE: Some PCs now come equipped only with a USB port. It may be possible to use an RS-232/USB converter with the programming cable supplied with the Jackrabbit Devel- opment Kit. Contact Technical Support (see Section 2.5.1) for further assistance. Rabbit 2000 Development Kit... -
Page 17: Connect Power
2.3.3 Connect Power When all other connections have been made, you can connect power to the Jackrabbit. Hook up the connector from the wall transformer to header J1 on the Jackrabbit board as shown in Figure 3. The orientation of this connector is not important since the VIN (posi- tive) voltage is the middle pin, and GND is available on both ends of the three-pin header J1. -

• Single-stepping. This is done with the key. The key can also be used for single- stepping. If the key is used, then descent into subroutines will take place. With the key the subroutine is executed at full speed when the statement that calls it is stepped over. - Page 26 The term while loop is used as a handy way to describe a style of real-time programming in which most operations are done in one loop. The while loop starts at (1) and ends at (7). The function BigLoopTop() Rabbit 2000 Development Kit...

Page 29: Chapter 4. Software Reference
EFERENCE To develop and debug programs for the Jackrabbit (and for all other Z-World and Rabbit Semiconductor hardware), you must install and use Dynamic C. This chapter takes you through the installation of Dynamic C, and then provides a tour of its major features with respect to the Jackrabbit. -

Page 31: Running Dynamic C
4.3 Running Dynamic C You have a choice of doing your software development in the flash memory or in the static RAM included on the Jackrabbit. The advantage of working in RAM is to save wear on the flash memory, which is limited to about 100,000 write cycles. NOTE: An application can be developed in RAM, but cannot run standalone from RAM after the programming cable is disconnected. -

Page 34: Jackrabbit Function Apis
This function initializes the digital outputs and sets up the driver for the analog input/outputs. The digital outputs correspond to the Rabbit processor’s port E bits 0–3, and the analog I/O uses timer B; bits 1, 2, and 4 of port D; and bits 6 and 7 of port E. - Page 35 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.

DA0 obviously cannot be used while an input voltage is being measured, although channel DA0 is still available.

Parallel Ports D and E on the Rabbit 2000 are double-buffered to provide precisely timed updating of the output pins. Each port is divided into an upper and a lower nibble. All bits of each nibble must be updated simultaneously. -
