Cannot debug demo project

Mon, 2017-05-29 12:35 -- akroizer

Hello,
I have the DA14585 board and I'm trying to run the "blinky" test app with Keil MDK.
I am running into the following issue:
When trying to debug the program, I am getting a dialog saying
"BP could not be set!
Expr: ,
Address: 0x20000af8
Probably too many Breakpoints defined?"

This is although no breakpoint has been defined. 0x20000af8 is the address of the first line of main().

GPIO Edge Interrupts

Fri, 2017-05-19 09:40 -- Eric Scammell

I'm attempting to use the GPIO interrupts to detect the rising and falling edges on some switches, but I'm having trouble with some interrupts firing as soon as I enable them using GPIO_EnableIRQ.
For example, I've got a rising-edge interrupt on a pin which is initially low. There's also a falling-edge interrupt on the same pin which does not immediately fire.
Similarly the falling-edge interrupt fires on a pin which is initially high.

Is there any way to suppress this immediate interrupt so that my edge-triggered interrupts only fire on edges?

Can I use the SDK 6.0.2.243 for DA14580?

Hi,
Our board will be designed as a co-layout board.
We can't make a decision now on which chip we will use, maybe DA14581 or DA14585.
Thus, I am worry about which SDK is more suitable for out project.
If I choose SDK 6.0.3, is it possible to run the sample code both on DA14581 and DA14585? How?
Is there a definition such as "#define LET_THE_CODE_FOR_DA14581" and I can switch the code is for DA14581 or DA14585 by editing the definition?
Thank you.

Using Sample Rate Converter (SRC) for low bit depth and low sample rate audio

Thu, 2017-04-27 13:16 -- andy.heidt

Hello,
I would like to output a PDM stream from a low fidelity audio stream, but it's not clear whether the SRC and PDM peripherals support this. Here are my application details:

Audio file details:
- Stored in external flash
- Mono
- Bit depth: 8 bits
- Sample rate: 16 kHz

ble_app_all_in_one app not updated for SDK 6.0.2

Wed, 2017-04-19 18:21 -- jamey.hicks.cmt

I'm bringing up an app on the DA14585. Just to make sure I had everything I needed, I started with the ble_app_all_in_one app.

I've run into a couple of issues:
uart2_init() now takes 3 parameters, but this example and a couple of others still only provide 2. Fixed that in my copy.

Also, the defines for the UART changed from
GPIO_UART2_TX_PORT
and
GPIO_UART2_RX_PORT

to
UART2_TX_GPIO_PORT
and
UART2_RX_GPIO_PORT

and similarly for the pin macros.
