    • Terminal.getChar() type debugging The Javelin Stamp IDE is introduced in Chapter 2, and then discussed in more detail in Chapter 5. This IDE makes real-time debugging so easy that a PC emulator is completely unnecessary. It is just as easy to develop and debug on the Javelin module itself.

  • Page 21: How The Javelin Stamp Works

    The Javelin’s internal voltage regulation is done using a switching regulator. The switching regulator runs cooler and is significantly more efficient than a linear regulator. It accepts voltages between 6 and 24 V, and makes 5 V available for the Javelin Stamp with a total current budget of 150 mA.

    Figure 1.2 Javelin Block Diagram Javelin Stamp Hardware Table 1.1 shows the Javelin Stamp’s specifications. Note that the onboard voltage regulator can accept between 6 and 24 V and output up to 150 mA of current. Since the Javelin consumes approximately 60 mA, you have 90 mA available for other uses.
