    C H A P T E R 1 Stellaris® Family Development Board The Stellaris® Family Development Board provides a platform for product development. Hardware and software engineers use this board for evaluation of Stellaris™ family microcontroller features and functionality, and for software development. The development board includes the Stellaris motherboard and a daughterboard with a Stellaris family microcontroller.

  • Page 11: Functional Description

    Stellaris® Family Development Board User’s Manual Functional Description Daughterboard The daughterboard contains the Stellaris microcontroller and connects to the motherboard with four 21-pin connectors. The Stellaris PLL clock is generated from a 6-MHz crystal provided on pin sockets for easy crystal changes. An optional SMA connector can be used to drive an external clock source.

    Prototype Area A prototype area is provided for implementing user circuits. To supply power, there are power and ground rows. The prototype area is indicated on the board with a Luminary Micro logo (see Figure 1-2 on page 13). Peripheral Device Controller (PDC)

  • Page 13: Power Supply

    Stellaris® Family Development Board User’s Manual Power Supply The Stellaris® Family Development Board requires 5 volts at 500 mA for operation, and three options are provided for supply connection. A USB connector can be used when connected to a high-power (500-mA) USB hub port. A 5-V jack can be used with an external power supply.

    Stellaris® Family Development Board Development Board Configuration NOTE: In the descriptions that follow, reference designators are used to indicate locations on the board layout (as shown in Figure 1-2). In addition, reference designators in parenthesis refer to parts in the schematics in Appendix B, “Schematics. Daughterboard Installation The daughterboard connects to the motherboard header connectors J1-J4.

  • Page 15: User Pushbutton

    Stellaris® Family Development Board User’s Manual User Pushbutton Pushbutton SW3 is available for general use. To connect this switch to PB4, place a shunt jumper on JP19. To use a different port, remove shunt at JP19 and connect a fly-wire from the desired port to JP19-2.

  • Page 16: Reset Switch

    Stellaris® Family Development Board Reset Switch Reset switch SW2 generates a 140-ms (minimum) system reset signal. Powering up the board also generates a 140-ms system reset signal. A shunt jumper can be placed on JP20 to link the JTAG emulator reset with the system reset. GPIO Headers All Stellaris GPIO ports are available on 8-pin headers labeled PortA (J5), PortB (J6), PortC (J7), PortD (J10), and PortE (J12).

  • Page 17: Stellaris Microcontroller To Pdc Interface

    Stellaris® Family Development Board User’s Manual Stellaris Microcontroller to PDC Interface The Stellaris microcontroller connects to the PDC with a SPI port using the signals shown in Table 1-2. Table 1-2. Stellaris Microcontroller to PDC Interface Board Signal Direction Description SPI_CLK Input SPI clock signal, 1 MHz.

  • Page 18: Pdc Registers

    Stellaris® Family Development Board PDC Registers PDC registers are 8 bits, and there are three types: Read-Only (RO), Read/Write (R/W), and Read/Write delayed (RWD). A RWD transaction requires an additional dummy transfer due to peripheral device latency. Table 1-4. PDC Registers Register Type Description...

  • Page 19: Spi Protocol

    Stellaris® Family Development Board User’s Manual Table 1-4. PDC Registers Register Type Description Address GPXDIR The GPIOX Direction (GPXDIR) register is used to select the data transfer direction for the GPXDAT register. Bit i corresponds to GPXDAT bit i. Writing a bit to 1 sets the corresponding GPXDAT bit as an output port.

  • Page 20: Figure 1-3. Pdc Timing Diagrams

    Stellaris® Family Development Board Every transaction is composed of at least two 8-bit SPI transfers. The first byte contains a 4-bit address on the lower bits (bits 3:0) and a read/write (R/W) bit to indicate transfer direction on the most significant bit (bit 7). The remaining bits (bits 6:4) are reserved and must be 0. The next byte is driven by the Stellaris microcontroller for write transfers (R/W bit=0), and by the PDC for read transfers (R/W bit=1).
