3.2.4
In this configuration, the starter kit has been programmed with a debugged,
stand-alone USB embedded host application; programmer/debugger support is not
needed. Because of the absence of a host PC, this configuration can truly be
considered a “stand-alone” operation.
Since there are no connections to a host PC, the starter kit board must be physically
modified to accept an external power supply. A regulated power supply providing 5 V
must be available.
Make the following modifications to the starter kit (Figure 3-3):
1. Install posts at the V
2. Populate the site for R16 (adjacent to the V
3. Supply +5 V
FIGURE 3-3:
If the modifications are done correctly, and power is connected correctly, the green
Target Power LED (D4) is lit. The starter kit also goes through its power-on sequence
before LED1 displays the “PIC24 Starter Kit” main menu.
When configured for external power operation, the programmer/debugger function is
essentially disabled. To re-enable these functions, disconnect the external power from
the board and remove the resistor/jumper from R16 before connecting the USB cable
to J1.
If you externally power V
disconnect any USB cables connected to a computer or hub. Otherwise, damage to the
PC’s USB port or the external hub may result.
