    Measuring Power Consumption on CY8CKIT-042-BLE

    tkosiyat_1665816

      I tried to measure the power consumption of CY8C4247LQI-BL483 device while it is in DeepSleep mode. I followed the instruction in "Project # 27: PSoC 4 BLE - Power Consumption Optimization" by measuring current across the jumper J15. The main() function consists of four lines of code as follows:

         

      CySysClkIloStop();
      CySysClkEcoStop();
      CySysPmDeepSleep();
      while(1);

         

      The current across the jumper J15 shows around 1mA. But when I took the device out of the development kit and feed 3V directly to the device via VDDD and GND and measured the power consumption (between 3V source and VDDD), I got around 3uA as expected. I'm not sure what I did wrong when I try to measure the power consumption from the jumper J15.
