I wana connect an I2S microphone to DA14681 microcontroller and get data of that.
Is there any sample or reference code for implementation and initialization of I2S peripheral in DA1468x?
if is not, what can i do?
Hello Dialog team,
I am working on Dialog DA14681 "DA1468x_DA15xxx_SDK_22.214.171.1242" SDK. Initially I want to off BLE advertising and when we detect any pin interrupt we need to enable BLE advertising for five minutes of time period and again disable BLE advertising until it's not detect any pin interrupt and so on.
Please let me know the API call for BLE advertising disable and enable.
Any help will be appreciated.
I'm working on a project using the DA1468x with SDK DA1468x_SDK_BTLE_v_126.96.36.1990.1.
For this project we need to run a critical section of about 400µs. And we use the Timer0 to trigger periodically this section.
We would like to run this section in the timer handler, but after few seconds we reach the following assert :
ASSERT_WARNING(ble_slp_delays_cnt < (BLE_MAX_DELAYS_ALLOWED + 1));
What is the consequence for BLE if this assert is true ?
What is the aim of the BLE_MAX_DELAYS_ALLOWED define ? How should it be configured ?
Do we need to connect VDDIO (pin b2) to an external voltage (like 1V8)? For example, the diagram on page 10 of Application Note AN-B-061 (Application Hardware Design Guidelines) shows VDDIO externally connected to "V18". Alternatively, perhaps VDDIO is supplied internally, and we don't need to supply it by connecting it to a power rail?
I've build the demo project ble_adv (release QSPI)
And then I debug it ,there are many error information:
SEGGER J-Link GDB Server V5.12f Command Line Version
JLinkARM.dll V5.12f (DLL compiled May 17 2016 16:03:35)
Is the ADC clocked internally with a 200 MHz or 20 MHz clock? The datasheet mentions a 200 MHz clock, but the sampling time calculations are done with ADC_CLK=20 MHz, and I’m not sure where 20 MHz came from? If I choose the digital clock, does this mean the ADC uses the PLL instead as the SAR clock?
we are using the DA14681 Development Kit - Basic and Windows 10. In UM-B-047 it is described that the Device will show as 2 USB Serial Ports which are mapped to two COM Ports.
At first this worked but after some programming of the templates it stopped working. The COM Ports don't get recognised anymore. I tried to uninstall the Drivers and
plug in the Development Kit again but this didn't help. Do you have any Idea how I could fix this?
we want to use the Murata UMAC Lithium ion battery as the primary power source. It has a charge voltage of 2.7V with a capacity of 3mAh, more than enough for our case.
According to the data sheet of DA1468x, unfortunately the charge voltage of the built-in Constant Current/Constant Voltage charger can only be set down to a minimum of 3V.
Is there any other option to charge this battery type with the built-in charger? Maybe with a few additional components (not talking about a seperate charger IC)?
Thank you for any hint
From Page 12 of AN-B-061 DA1468x Application hardware design guidelines v1.3.pdf
An inductor having a saturation current
of at least 1A and a RDC of maximum 0.1 Ohm guarantees a good performance
Could you please help further explain why require the inductor having a saturation current
of at least 1A and a RDC of maximum 0.1 Ohm ?
