Would you tell me how to Measuring MCU sleep mode current.
The environment used is as follows.
Board : EV-COG-AD4050LZDevice : ADuCM4x50Pack : AnalogDevices.EC-COG-AD4050LZ_BSP.3.1.0Example : rtc_alarm_example(EV-COG-AD4050LZ)
Multimeter : Agilent 34410A
The measurement environment followed the article below.
EV-COG-AD4050LZ Development Kit [Analog Devices Wiki]-> Power Measurement on EV-COG-AD4050LZ MCU COG-> Measuring MCU sleep mode currentwiki.analog.com/.../ev-cog-ad4050lz
The measured value is about 4.17 mA in Active mode, and about 1.2 uA in Hibernate mode.Can you think why the current value is slightly high?
You can use the current example that your using right now. Please take note that with the debugger connected it will not enter in sleep mode so make sure that your operating on stand alone…
Please see this link it will guide you on how to do a power measurement on Cog boards.
Hi Jeric,Thank you for you reply.
Would you tell me the code being executed during this measurement?
You can use the current example that your using right now. Please take note that with the debugger connected it will not enter in sleep mode so make sure that your operating on stand alone mode(no debugger connected), in doing this remove all printing function or you can redirect them to UART for test purpose you can visit this link for more details.
The problem was solved using Releace mode.You’ve been very helpful.
