Use DA14681 SWD pins as ADC

Mon, 2020-06-01 20:07 -- mahmed106

Hi dialog

i m using a board based on DA14681 and i want to use 6 thermistors , and for that i have to use one ADC pin that is shared with SWD pins, (SWD CLK and SWDIO).

I confured this pin but it didnt work, then from this query  i came to realize that debugger needs to be disabled for this pin to work, (https://support.dialog-semiconductor.com/forums/post/dialog-smartbond-bl...)

but still no progress.

Dear Dialog,

i implemented a da14681 on a custom system on chip.

My system runs on a lithium ion batterie.

My problem is that the socf function is crashing my system when activated, the board is not booting and thus it is not possible debug easily.

I implemented a workaround in which i retreive manually the battery voltage through the ad_battery_raw_to_mvolt() function and then calculate the battery level through linear regression.

Battery charge in ProDK board

Sun, 2020-05-24 06:35 -- johnmayall

Hi Dialog,

I am using DA14683 ProDK board and SDK version is DA1468x_DA15xxx_SDK_1.0.14.1081

I want to test battery charge function in the ProDK board but it seems not work!

The following are my settings:

(1) Use pxp_reporter project in SDK and uncomment #define DEBUG_SOC in custom_config_qspi.h

(2) Connect Lithium battery(500mAh) on J10(pin1: VBAT- to battery negative terminal, pin 2 to battery positive terminal, pin 3 NTC is not connected)

(3) Switch SW2 on the daugtherboard to VBAT

(4) Place jumper on header J9, on position 1-2

spi2 bus clock and mosi pin do not output signal.

Hi,

I'm trying to communicate with ST7735 for lcd display and bio sensor in the DA14683 Development Kit.

Both ST7735 and bio sensor are SPI bus protocol. I want to set ST7735 on spi 2 and bio sensor on spi 1.

I had test ST7735 on spi1  and it is work.

However, I modify st7735 from spi 1 to spi2, csn pin is work but the clock and mosi pin do not output signal.

Measurment result as attached file.

Is there any parameters or api need to setup?

DA14683-USB disconnecting/crashing

Sat, 2020-05-09 20:27 -- electromotivated

Hello,

I'm evaluating the DA14683 using the DA14683-USB DK. I've compiled and loaded the DialogSemi\projects\workspace-ble-adv\projects\dk_apps\features\ble_peripheral project. After pressing restart I can see the device's advertisements in my BLE development app, and can even connect. However, after ~10 seconds the device disconnects/crashes. I have to hit the reset button again to restart the device, at which point it crashes again after ~10 seconds. It looks like most of the da14683 tutorials and demo code are for the da14683-basic and -pro dks.
