(Dynamic C). This kit con- tains a powerful single-board computer (the Jackrabbit board). With this kit you will be able to write and test complex software. You will be able to prototype circuits that interface to a Rabbit 2000 microprocessor. 1.1 Development Kit Contents The Rabbit 2000 Development Kit contains the following items: •...
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.
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.
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.
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-...
SELV levels (42.4 V AC peak, or 60 V DC). Damage to the Rabbit 2000 microprocessor may result if voltages outside the design range of 0 V to 5.5 V DC are applied directly to any of its digital inputs.
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.
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.
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.
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...
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.
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...
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.
PC cannot handle the default debugging baud rate. Try lowering the debugging baud rate as follows. • Locate the dialog in the Dynamic C Serial Options Options > Communications menu. Choose a lower debug baud rate. Rabbit 2000 Development Kit...
2.5.1 Technical Support NOTE: If you purchased your Jackrabbit through a distributor or through a Rabbit Semiconductor partner, contact the distributor or partner first for technical support. If there are any problems at this point: •...

• 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.

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...
used to collect some operations that are helpful to do once on every pass through the loop. Place the cursor on this function name and hit to learn more. <Ctrl-H> BigLoopTop() 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.
( "%02x -> %02x\n",nEcho,nReply ); NOTE: If your version of Dynamic C is earlier than 6.55, see Technical Note 117, Jack- rabbit (BL1800 Series) RS-485 Bulletin, for information on restrictions on using both DA1 and RS-485 at the same time.
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.

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.

4.4 Switching Between Program Mode and Run Mode The Jackrabbit is automatically in Program Mode when the programming cable is attached, and is automatically in Run Mode when no programming cable is attached. See Figure 5. Program Mode Run Mode RESET Jackrabbit board when changing mode: Short out pads below header J5,...
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.

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 4.5.1.4 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.
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.

A.4 Use of Rabbit 2000 Parallel Ports Figure A-3 shows the use of the Rabbit 2000 parallel ports. The BL1810 Jackrabbit has 24 general-purpose digital inputs/outputs available on headers J4 and J5—14 are bidirec- tional, six are inputs only, and four are outputs only, as shown in Figure A-3.
Specifications are based on characterization of tested sample units rather than testing over temperature and voltage of each unit. Rabbit Semiconductor products may qualify components to operate within a range of parameters that is different from the manufacturer’s recommended range.
