Power Measurements
Two locations are provided for measuring the current draw from various
power planes. Precision 0.1 ohm shunt resistors are available on the
VDDEXT and VDDINT voltage domains. For current draw, the jumper
is removed, voltage across the resistor can be measured using an oscillo-
scope, and the value of the resistor can be measured using a precision
multi-meter. Once the voltage and resistance are measured, the current
can be calculated by dividing the voltage by the resistance. For the highest
accuracy, a differential probe should be used for measuring the voltage
across the resistor. For more information, refer to

Example Programs
Example programs are provided with the ADSP-BF592 EZ-KIT Lite to
demonstrate various capabilities of the product. The programs are
installed with VisualDSP++ 5.0 update 8 onwards (on top of the
VisualDSP++ 5.0 base kit) and can be found in the
<install_path>\Blackfin\Examples\ADSP-BF592 EZ-KIT Lite
Refer to a readme file provided with each example for more information.
