[shital]

hello all ,

controller nrf51822  

i am trying to development for EPD 7.5 spi interfacing  through external flash image send .

my question is i am using reference code for EDP 1.44 so  github.com/.../57e0c2c8819f55c0fc989e6f77781e9d04cc2b8b  

so any register value are changes or not ? 

if yes then witch value are change how to change 

thanks and regard,

Your question isn't very clear, but I'm assuming you are trying to interface a 7.5 inch E-ink Paper Display using code written for a 1.44 inch EPD and wondering whether you have to make changes to the code?

You should read the datasheet for both EPDs and compare them. At the very least I guess you will have to change some parameters defining the resolution.

i am written code 7.5 inch E-ink Paper  ,

i compare both data sheet but not understand . 

 like register command same or not i am not clear

I'm sorry, but differences between datasheets for various e-ink paper displays are not Nordic related. You might have better luck if you ask on a forum dedicated to general electronics or e-ink displays. If you have specific questions related to Nordic products I'll be happy to help though.

I suggest that you follow my colleague Andreas' suggestions in your other thread about this.
