JTag Connection Failing

Wed, 2019-05-01 00:23 -- ddustin

I have setup a jtag plug as per the attached schematic. I copied this schematic from one of the examples.

Then I got the Segger J-Link EDU device here: https://www.amazon.com/gp/product/B017U578UW

Plugged it into the J-Lilnk Emulator JTAG device here: https://www.amazon.com/gp/product/B00RBHOSTY so the cable could attach

And then I ran "JLinkGDBServer" and attempted to connect using SWD. The connection seems to fail every time.

 

怎么使用SDK的I2C驱动配置多个I2C设备

Sun, 2019-04-28 12:15 -- lisir

最近在做一个DA14583平台的项目,项目里用到了多个I2C设备,对于官方给的Demo里面的函数i2c_eeprom_init只能初始化一个从设备的地址,对于多个I2C设备的地址该怎么初始化呢?这个初始化的函数应该放在哪一块?为了节省IO口,多个I2C设备能挂在同一条I2C总线上吗,就是只用两个IO映射SDA和SCL,然后所有I2C设备都挂在这两个io口上,还是必须用多个IO口,一个设备对应两个IO。在扩展睡眠模式下,使用app_easy_timer能够周期性依次读取I2C设备数据吗?

how to configure two I2C devices using the driver from the SDK

Sun, 2019-04-28 10:56 -- lisir

we now use two I2C devices in our DA14583 project, the devices have different slave address, so i don`t know how to use the I2C dirver from the SDK to configure my devices,like how to use the function 'i2c_eeprom_init()' to initilize the I2C interface. And i also want to know the two devices can use the same IOs(SDA,SCL in the two devices tied with just two IOs) or they can use different IOs(SDA,SCL in the two devices tied with four IOs).

DA14583射频输出异常

Sun, 2019-04-28 08:06 -- Zhangkui

Dialog,您好:

我从安富利购买了5000片da14583用于产品的生产,焊接完成后的发现有10%左右的板卡出现了无蓝牙广播信号输出的现象,有问题的板卡可以正常下载运行程序,但是无射频信号输出,通过示波器可以看到RFIOP管脚处有附件所示的奇怪波形,而正常工作的板卡该管脚处无此异常输出,将正常和不正常板卡上的da14583对调,可以发现问题是由da14583造成的,和外设没有关系,请问为什么会出现这种现象呢?期待您的回复,谢谢!

 

 

UNABLE TO NOTIFY LARGE DATA

Fri, 2019-04-12 09:00 -- Utkarash

Hello All,

I have used BLE peripheral example as reference where i have addded one characteristics in which i want to exchange data of around 180 bytes.

I am able to send 180 bytes of data to mobile application (tested on BLE Scanner for iOS and nrf Connect for Andriod) ,

However, when i want to notify the same data using app i am not able to get correct data in one shot,

That is in firmware i made a provision that when i receive a certain command from BLE application the firmware should reply with these 180 bytes of data,

DA14583 flash read / write

Tue, 2019-04-02 18:50 -- Rajapurerohit

Dear Dialog Support,

I need very urgent help in the flash read/ write procedure.

I have designed a device using DA14583 MCU, and I have written code where on the button press i am toggling the group of LED bulbs.

To operate LED bulbs, created a packet of data (packet include the number of bulbs and their address) which assigning from BLEScanner to custom device.

Next thing in firmware I read packet sent from the app I parsh it as per my application and store values/ data into flash( storing of data is perfectly happening ).

Raw Data - 100 Hz

Mon, 2019-04-01 10:09 -- gomezago

Hello, 

I'm working with the DA14583, I want to use it to acquire raw data from the Accelerometer, Gyroscope and Magnetometer at a frequency of 100Hz without using the Sensor Fusion algorithm.  

I have built an Android App based on the provided source code, but I'm not sure about what kind of modifications should I make to the app/firmware in order to be able to acquire as I want to. (My final goal is to LOG the raw data every 10ms) 

Any suggestions and guidance would be higly appreciated,

Alejandra 

Receiving uart data after replacing DA14583 chip

Wed, 2019-03-27 17:00 -- ReinierH

Hi All,

I replaced the DA14583 chip on my pcb because it's OTP memory was flashed. After reconnecting it to an UART -> usb connector using P0.6 and P0.7 I noticed that the chip is sending out bytes:

 

00 fc 00 fe 00 fc 00 fe  00 fc 00 fc 00 fc 00 fc

I'm trying to flash it using my self writting uart flashing tool but I the uart output from the chip is not what I expected (0x02). 
Can someone explain what this is and what I can do to write my binary to RAM?

Cheers,

Reinier
