5.2.1.6 Power Interface
The Power interface measures the power consumption of the connected circuitry.
Select the Power interface beneath the debug tool DGI. Set up the interface using the controls under “Power Settings.”
| Control | Value | Usage |
|---|---|---|
| Enabled Channels | A, A+B | Either enable channel A only or both channels A and B. Channel A is always enabled. |
| Lock Channel A in high range* | Unchecked, checked | Channel A can be locked to the high range to avoid automatic switching to the low range. This allows detection of short spikes in current consumption without critical samples being lost when switching between the ranges. |
| Output Voltage in mV | Between 1600 mV and 5500 mV, or 0 | The MPLAB ICE 4 features an adjustable target supply that can be used to power the target application. This setting enables and controls the output voltage of this supply. A selection of 0 disables the supply. |
| * Future feature. | ||
Tip: Any setting changes will not
take effect until clicking Apply in the Power Settings panel. E.g., to enable the
Voltage Output, the Output Voltage value set and Apply must be clicked before the
voltage output will actually be enabled and set accordingly.
Tip: The channel A range lock
will not force the debugger to return to the high current range if already running in
the low range. Either wait for a current high enough to force it to change, or simply
Stop and Start the debugger.
Tip: Each power signal time plot
uses system resources. Reduce the number of concurrent plots for better
performance.
