Power Architecture - using DA9070

Forums:

We (Vadict Innovations Pvt Ltd/Vadict Inc) are designing a new sensor product that should support power from various sources. Kindly see attached our tentative power architecture.

Looking at Dialog's portfolio, we found out DA9070. Looks like it will fit well, still looking at the architecture, can Dialog suggest the best suitable part? What other components can Dialog suggest?

Our development center is in India, so what kind of support do you provide for India? Do you have FAEs in India?

Do you have a development kit for DA9070?

Dialog Smartbond Bluetooth Low Energy – Hardware (device & reference designs)

Hi everyone,

We are facing a high priority issue. We are not able to flash into our own design board(DA14580)

By using Segger J Link lite, we made connections

J link 7th pin - SWDIO of Design Board

J link 9th pin - SWCLK of Design Board

J link 20th pin- GND of Design Board

我们正在努力闪现SPI flash memory of the design board using SWD interface. After opening connected J link in Smart Snippet toolbox getting error

Hi,

I'm new to Dialog products and my end goal is to use the DA14580 as a external/connectivity chip with my own custom service and characteristics.

Dialog Smartbond Bluetooth Low Energy – Tools

Hi

I have installed SDK 5.0.4 Trying to upload firmware into DA14580.

D:\1new\5.0.4 // SDK location

D:\SmartSnippetsStudio2.0.12 // Studio location

D:\SmartSnippetsToolbox5.0.12 // Toolbox location

I have followed this

Please try to change the regions setting and after that follow the steps below:

ADC sample with GP_ADC_ATTN3X

Dialog Smartbond Bluetooth Low Energy – Hardware (device & reference designs)

We're trying to read the voltage from a resistor divider (NTC thermistor and a fixed R). We use P01(single end) and the reference voltage is 3.6V. We set GP_ADC_ATTN3X, we find the result is different from what we suppose. We find Figure 55 of the datasheet, but we have some problems. When we set GP_ADC_ATTN3X to 1, how does the above switch connect? If we set it to 1, can we think P01 always parallel 300KOhm resistance ( 200K + 100K )? If we set it to 0, dose P01 connect to the ADC module directly (no any parallel resistance)?

Hi Everyone,

What's the power consumption for advertising in Peripheral Mode and Broadcaster Mode?

Is it thesamefor both Modes or advertising in Peripheral Mode will takemorepower?

ADC采样基于3.6V参考电压，芯片内部是否内置了300K欧姆的电阻？能否去掉？

Forums:

Dialog Smartbond Bluetooth Low Energy – Hardware (device & reference designs)

我们采用ADC采样一个精密电阻的电压，基于3.6V参考电压，设置了GP_ADC_ATTN3X。但是测出来的电压值和我们的理论值差别比较大。我们查手册发现Figure 55里，芯片内部是内置并联两个电阻，加起来300K欧姆。请问我们的理解是否正确？另外，这两个电阻可否取消？

PMIC, Audio and Haptics Questions

I’m using a DA9062-EVAL3 board and I am able to program blank ICs and also to test the power sequencing of the BUCKx and VLDOx outputs on my oscilloscope. The steps I take here are (1) connect the oscilloscope probes to the EVAL3 board's BUCK/VLDO output pins, (2) turn the switch to TP_OFF, and (3) turn on the power supply (5V, 0.5A). This works well!!

I2C pullup resistors needed?

Forums:

GreenPAK and GreenFET questions

Hello,

I noticed that the resistors R2 and R3 I2C pullup are not mounted on the SLG46826V-DIP board.

There is no option in the GreenPAK6 software to enable pullups on the I2C pins. Also, pullups are included on the GreenPAK In-System Programming Board. But I am wondering what happens to these pins when the SLG46826 chip is running stand alone. ie. will they be susceptible to noise?

So my question is do I need to include I2C pullup resistors on my board for the SLG46826?

Thanks, Ken
