    To help familiarize you with the RCM3700 modules, Dynamic C includes several sample programs. Loading, executing and studying these programs will give you a solid hands-on overview of the RCM3700’s capabilities, as well as a quick start with Dynamic C as an application development tool.
  • Page 18 The default I/O configuration in the sample programs is based on the RabbitCore module detected during compile time: • Any RCM3700 RabbitCore module (except the RCM3720) will have its I/O ports con- figured for an RCM3700 Prototyping Board. • An RCM3720 RabbitCore module will have its I/O ports configured for an RCM3720 Prototyping Board.

    The RCM3700 takes advantage of the Rabbit 3000 microprocessor’s internal clock doubler. A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emis- sions. The 22.1 MHz frequency specified for the RCM3700 is generated using a 11.06 MHz resonator.

    The hub relays packets received on any port to all of the ports on the hub. Hubs are low in cost and are readily available. The RCM3700 uses 10 Mbps Ethernet, so the hub or Ethernet adapter must be either a 10 Mbps unit or a 10/100 unit that adapts to 10 Mbps.

  • Page 68: How Ip Addresses Are Used

    Each RCM3700 RabbitCore module has its own unique MAC address, which consists of the prefix 0090C2 followed by a code that is unique to each RCM3700 module. For exam- ple, a MAC address might be 0090C2C002C0.

  • Page 69: Dynamically Assigned Internet Addresses

    The DHCP server may try to give you the same address each time, but a fixed IP address is usually not guaranteed. If you are not concerned about accessing the RCM3700 from the Internet, you can place the RCM3700 on the internal network using an IP address assigned either statically or through DHCP.

  • Page 70: Placing Your Device On The Network

    You can either place the RCM3700 directly on the Internet with a real Internet address or place it behind the firewall. If you place the RCM3700 behind the fire- wall, you need to configure the firewall to translate and forward packets from the Internet to the RCM3700.

    ROTOTYPING OARD Two different Prototyping Boards are available for the RCM3700 series of RabbitCore modules. The RCM3700 Proto- typing Board has power-supply connections and also provides some basic I/O peripherals (RS-232, RS-485, A/D converter, IrDA transceiver, LEDs, and switches), as well as a prototyping area for more advanced hardware development.

  • Page 93: Rcm3700 Prototyping Board

    The RCM3700 Prototyping Board included in the RCM3700 Development Kit makes it easy to connect an RCM3700 module to a power supply and a PC workstation for devel- opment. It also provides some basic I/O peripherals (RS-232, RS-485, A/D converter, IrDA transceiver, LEDs, and switches), as well as a prototyping area for more advanced hardware development.

    The RCM3700 Prototyping Board comes with the basic components necessary to demon- strate the operation of the RCM3700. Two LEDs (DS1 and DS2) are connected to PF6 and PF7, and two switches (S1 and S2) are connected to PF4 and PB7 to demonstrate the inter- face to the Rabbit 3000 microprocessor.

  • Page 100: Analog Features

    B.1.5 Analog Features The RCM3700 Prototyping Board has an onboard ADS7870 A/D converter to demon- strate the interface capabilities of the Rabbit 3000. The A/D converter multiplexes con- verted signals from eight single-ended or three differential inputs to alternate Serial Port B on the Rabbit 3000 (Parallel Port pins PD4 and PD5).
