DA14681 custom data read/write

Wed, 2018-02-21 21:12 -- Jitendraprasad

Hello Dialog team,

I am working on DA14681 MCU based custom board. DA14681 connected to "W25Q80EW" flash memory via qspi interface. This flash memory is use for save sensors log data.
But problem is how can I use this flash memory with DA14681 MCU. I mean configuration with qspi and read/write operation.
Could you please help me to read/write dummy data into flash memory.

Thanks in advance.

Coexistence is not work.

SDK Ver. 1.0.12.1078
EVK : DA14681 PRO Development kit

I saw coexistence architecture in datasheet page 159.
And I added the following to the source code to check case 3 on page 160:

1. PMU_CTRL_REG[PERIPH_SLEEP] = 0.
2. the CLK_RADIO_REG[RFCU_EN] bit has to be asserted before programming the block’s registers.
3. Pxy_MODE_REG[PID] = 48 or 49 (COEX_EXT_ACT0 or COEX_EXT_ACT1),
4. SMART_ACT (Pxy_MODE_REG[PID] = 50)
5. SMART_PRI (Pxy_MODE_REG[PID] = 51)
6. COEX_CTRL_REG[SMART_ACT_IMPL] = 1

How to check what´s being received by the DA 14681 dev board during SUotA update through App

Tue, 2017-12-05 07:49 -- vinesh_gowda

Hello,

I need to know what the Android App is sending to the board or what the board is receiving during the SUotA. Is there any method to check this or are there any particular lines/files in the SUotA loader program where I can debug as soon as I start receiving the data from the app(mobile phone)?

DA14681 chip revisions

Mon, 2017-07-24 18:10 -- chriskang88

We have built boards in two different phases. The first one was a SW dev board which is a large board and the other one was actual form factor boards.
The first boards are able to be programmed flash but the second one is not.
We've been checking what is different between two boards but not successfully found a root cause yet.
One difference is the chip revision.
On the working boards, there is DA14681-01000 and on non-working boards there is DA14681-AD000.
I couldn't find what is difference on the new revision on the datasheet.

LP4 on DA14681 dev kit (basic)

Mon, 2017-03-27 17:16 -- jamesleo-konka

Hi, Dialog,
I found that there is no component LP4 on my DA14681 dev kit (BASIC) -- which connet the VBUS to MCU and extended IO port.
What will happen if I solded one inductor at LP4? Is there any changes should I do? -- I want to connect VBUS to my child board.

BTW, is the sample project 'usb_cdc' suitable for Dual Power Mode? -- Low power mode if no USB plug in, High speed mode when USB pluged in.
Is there a sample code for this dual power mode?

Thanks

UART2 pin on DA14681 board (basic)

Hi Dialog,
I want to use UART2 to communicate with other device.
But I don't know which port/pin is ready for UART2.
