Battery Profiling

Mon, 2021-01-04 16:09 -- dlo

I've looked into the UM-B-075 and how to profile a battery using the smartsnippet tools. However without having those equipment I'm not able to run the provided software to generate the LUTs.

I have a DL3021A load meter with battery profiling capabilities I've used to gather data.

In my case I'm using a 110mAh lithiuom ion battery. Am I correct in assuming that the LUT is generated using these principles?

100% = 0mAh discharged from battery

90% = 11mAh discharged from battery

80% = 22mAh discharged from battery

Hi dialog

I have done fresh installation of smart snippets studio on two different PC's that didnt had elipse or smart snippet studio before. 

On both PC's i m facing an issue while doing JTAG flashing of DA14681. After all steps, when eclipse attempts to reboot the chip, following error message occured. 

 

C:\sdk\DA1468x_DA15xxx_SDK_1.0.14.1081\utilities\scripts\qspi\reboot_device.vbs(9, 1) WshShell.RegRead: Unable to open registry key "HKCU\Software\SEGGER\J-Link\InstallPath" for reading.

 

Characterize SIMO

Mon, 2020-11-30 20:09 -- dlo

I'm trying to characterize the quiscent current for the various power domain inside the DA14683.

I would like to know how I can use the SIMO for both 1V8 and 1V8P in extended sleep.

In searching through the code I believe the function apply_wfi inside sys_power_mgr.c is responsible for placing the DA14683 into the desired sleep state.

I tried commenting out:
 

How to configure LDO_USB to be on in extended sleep mode

Wed, 2020-11-18 09:57 -- fschuette

Hey there,

I'm using the Dialog DA14682 and am powering it via USB. In the datasheet it says on page 27 (extended sleep mode):

LDO_USB=OPT

*OPT: optionally on or off, configurable by SW.

Where can I configure this LDO to be running when being in extended_sleep mode?

Thanks
