Bypass internal DC/DC

Thu, 2017-10-05 08:16 -- sampullman

Hello,

I am planning to add a DA14585 to an existing system, and have a few questions about bypassing the internal DC/DC:

1. The method in the FAQ refers to DA14580, does it work the same way for DA14580?

2. Will the attached power circuit work? We may reduce supply voltage to 3.1V.

Maximum size of the SPI external memory with a DA14585

Sat, 2017-09-30 15:22 -- rodrigopex

Hi,
I am planning to store 16MB (or 32MB) of data on my node. I would like to know if the DA14585 supports this amount of data in an external memory. It will suit perfectly on my solution. Can you help me on that? Another little thing, at the documentation of how using external memories with DA14585 you provide a supported list of memories. Is it mandatory or would I use another out off the list with the same features?

Best regards,
Rodrigo Peixoto.

OTP cannot read

Tue, 2017-09-26 11:43 -- stanley_yeh

Dear support team,
I am trying to write something into OTP.
I am using the function "otp_write_words" to write OTP.
I wrote some data into the address 0x7F8FDF0 in my code as following steps...
1. Write 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01
2. Read the address, got 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 ==> correct
3. Write 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x02
4. Read the address, got 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x03 ==> correct, because (0x01 | 0x02) = 0x03

Device not waking up from extended sleep

Thu, 2017-09-21 07:52 -- wisilica

Hi,

I am working on the project wherein the default sleep mode of the device is extended sleep mode. I am trying to wake the device up using both synchronous and asynchronous mechanisms.
The problem we are facing is the device does wake from the timer callbacks, but is not waking up from external interrupt.
Following is the code snippet used for wake up configuration using external interrupt :
void set_pad_functions(){
GPIO_ConfigurePin(GPIO_ACC_INT2_PORT, GPIO_ACC_INT2_PIN, INPUT_PULLDOWN, PID_GPIO, false);
}

Development environment requirements

Wed, 2017-09-20 21:52 -- erichn

I'm looking to get started developing software for the DA1458x series. From what I've gathered from a couple forum posts, development under Linux is simply not supported. (This seems strange, since someone took the time to make SmartSnippets Studio run in Linux.) It appears that I will need to use Windows. If that is true, I would like to know if an unlicensed (Lite) version of Keil is sufficient. I did not see a good list of the system prerequisites for setting up the development environment, so it's unclear whether I would need to purchase the full version of Keil to get this to work.

Getting interrupt on GPIO - DA14585

Mon, 2017-09-18 10:34 -- wisilica

Hi,

I am working on a project wherein. the device is in extended sleep mode by default. The device needs to wake up and advertise custom data on receiving an interrupt on a particular GPIO (PORT X, PIN Y) which is connected to an accelerometer device. Please suggest the steps that are required to configure the GPIO for receiving interrupts and waking up the device.

Thanks
