Battery Profiling

Forums:

Dialog Smartbond Bluetooth Low Energy – Software

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

Can this pin:USBP/P2_2 control the LED as general gpio?

Dialog Smartbond Bluetooth Low Energy – Software

Hi Dialog,

I want to turn on/off the led. So connect USBP/P2_2 to red led.

We only have this pin available. Can this pin:USBP/P2_2 control the LED?

Thanks.

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.

1.8V power surge on USB Plug

Forums:

Dialog Smartbond Bluetooth Low Energy – Tools

Hello,

We have a power surge on the 1.8V provided by the DA14681 when we plug the USB. Measurements are in the files attached

After the surge, the 1.8V is stable.

The overshot may damage the components using the 1.8V.

There is a way to remove this overshot?

Regards,

Thomas

Characterize SIMO

Forums:

Dialog Smartbond Bluetooth Low Energy – Software

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

Forums:

Dialog Smartbond Bluetooth Low Energy – Software

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

DA14681 Reset Pin Maximum Input Voltage ?

Forums:

Dialog Smartbond Bluetooth Low Energy – Software

Hi dialog

We are working on a custom board based on DA14681, We are using external GreenPAK Saleigo CPLD for external reset and by default that CPLD is powered on by 5V.

What is the maximum input voltage that RESET pin of DA14681 can tolerate. Can we send 5V pulse to reset pin?

Hi Dialog,

1.

We didn't find out how to set the value of SystemCoreClock.
Eg. extern uint32_t SystemCoreClock;

I want to set Tick to 1ms in FreeRTOS. Please help me ?

2.

Our external oscillators are 32.768MHz and 16MHz. the maximum frequency of DA14683 is 96MHz.

But What is the actual frequency of system?
