1. INTRODUCTION The RCM4000 series of RabbitCore modules is one of the next ® generation of core modules that take advantage of new Rabbit 4000 features such as hardware DMA, clock speeds of up to 60 MHz, I/O lines shared with up to five serial ports and four levels of alternate pin functions that include variable-phase PWM, auxiliary I/O, quadrature decoder, and input capture. Coupled with more than 500 new opcode instructions that help to reduce code size and improve processing speed, this eq

1.2 Advantages of the RCM4000 Fast time to market using a fully engineered, “ready-to-run/ready-to-program” micro- processor core. Competitive pricing when compared with the alternative of purchasing and assembling individual components. Easy C-language program development and debugging Rabbit Field Utility to download compiled Dynamic C .bin files, and cloning board options for rapid production loading of programs. Generous memory size allows large programs with tens of thousands o

1.3 Development and Evaluation Tools 1.3.1 RCM4000 Development Kit The RCM4000 Development Kit contains the hardware essentials you will need to use your RCM4000 module. The items in the Development Kit and their use are as follows. RCM4010 module. Prototyping Board. AC adapter, 12 V DC, 1 A. (Included only with Development Kits sold for the North American market. A header plug leading to bare leads is provided to allow overseas users to connect their own power supply with a DC out

1.3.2 Software The RCM4000 is programmed using version 10.03 or later of Dynamic C. A compatible version is included on the Development Kit CD-ROM. Rabbit Semiconductor also offers add-on Dynamic C modules containing the popular µC/OS-II real-time operating system, as well as PPP, Advanced Encryption Standard (AES), and other select libraries. In addition to the Web-based technical support included at no extra charge, a one-year telephone-based technical support module is also available fo

2. GETTING STARTED This chapter describes the RCM4000 hardware in more detail, and explains how to set up and use the accompanying Prototyping Board. NOTE: This chapter (and this manual) assume that you have the RCM4000 Development Kit. If you purchased an RCM4000 module by itself, you will have to adapt the infor- mation in this chapter and elsewhere to your test and development setup. 2.1 Install Dynamic C To develop and debug programs for the RCM4000 (and for all other Rabbit Semiconductor

2.2 Hardware Connections There are three steps to connecting the Prototyping Board for use with Dynamic C and the sample programs: 1. Prepare the Prototyping Board for Development. 2. Attach the RCM4000 module to the Prototyping Board. 3. Connect the programming cable between the RCM4000 and the PC. 4. Connect the power supply to the Prototyping Board. 2.2.1 Prepare the Prototyping Board for Development Snap in four of the plastic standoffs supplied in the bag of accessory parts from the D

2.2.4 Connect Power Once all the other connections have been made, you can connect power to the Prototyping Board. Connect the AC adapter to 3-pin header J1 on the Prototyping Board as shown in Figure 4 above. The connector may be attached either way as long as it is not offset to one side—the center pin of J1 is always connected to the positive terminal, and either edge pin is ground. Plug in the AC adapter. The PWR LED on the Prototyping Board next to the power con- nector at J1 should li

2.3 Run a Sample Program If you already have Dynamic C installed, you are now ready to test your programming connections by running a sample program. Start Dynamic C by double-clicking on the Dynamic C icon or by double-clicking on dcrab_XXXX.exe in the Dynamic C root directory, where XXXX are version-specific characters. If you are using a USB port to connect your computer to the RCM4000, choose Options > Project Options and select “Use USB to Serial Converter” under the Communications ta

2.4 Where Do I Go From Here? If the sample program ran fine, you are now ready to go on to the sample programs in Chapter 3 and to develop your own applications. The sample programs can be easily modi- fied for your own use. The user's manual also provides complete hardware reference infor- mation and software function calls for the RCM4000 and the Prototyping Board. For advanced development topics, refer to the Dynamic C User’s Manual, also in the online documentation set. 2.4.1 Technical S
