Question

How to measure the power consumption of CPT112S with energy profiler ?

Answer

Sometimes we need to monitor the power consumption of CPT112S simply. The energy profiler in Simplicity Studio is a practical tool for energy consumption measurement, however, the CPT112S does not support energy profiler.

 

In fact, we can use another STK and makes it working under low power mode to minimize the effect on the final result, such as EM4. And then power the CPT112S board with VMCU of the STK board.

 

For example, use the EFM32ZG STK to measure the power consumption of CPT112S, the power consumption can be monitored within energy profiler as below.

This method also can be applied to other device in need.
