Hi
I am new to this. I want to display .bmp image on 2.9 inch e-paper display interface with DA14681 using bluetooth. Give me some idea about that.

Hi, arpitthumar
We do have customers making self-updated e-ink pricetags with our SoC, I'm not sure if that's the application you're interested.
The idea of sending data to a device on air through BLE and then update it to connected e-ink screen via a proper peripheral interface is not complicated, but to realize it some challenges like how to reduce the power consumption of each device and how to build a valid central hub to manage large quantities of devices are keys to make it happen. However, those cannot be simply discussed within a few words here.
You can get a DevKit and refer to our getting started guides to learn about how to create a simple BLE demo from scratch, displaying an image on an e-ink or whatever screen is essentially sending data to them via SPI or other interfaces of choice.
I have read UM-B-056-DA1468x Software Developer's Guide_6v0 in this there is no mention of SPI interface. Though can I still e-paper display with DA14681 using SPI? If yes, then from where I can get this tutorial to refer? Is it ok to use DA14583 or DA14681?
Hi,
DA14681 has a QSPI interface for flash and 2 SPI+ interfaces for other SPI peripherals. You can go through the datasheet to verify this.
For examples to follow, I think the peripherals_demo in the SDK is the one you should look into.
At where I will get all the SPI command part in tutorial to study? That How can I set and transfer the speed & data of an hex code array of a .bmp picture file that I have?
I want all the command information that SPI use to set all this?
And should I go for DA14583 or DA14681?
Hi arpitthumar,
You can download the UM-B-056-DA1468x Software Developer's Guide_6v0 from the 680 tab of our support portal. For your convenience, you can download it by following the link below:
https://support.dialog-semiconductor.com/resource/um-b-056-user-manual-da1468x-software-developers-guide-html
This document is for DA1468x family SoCs. I would highly suggest you to download the latest SDK of the 68x series (SDK1.0.14) and check the peripherals_demo example. Also, to getting started with the DA14680, it would be grate idea to have a look at our tutorials.
