Project by Gaurav Singh –
I have trying to get Kindle 6 inch e-ink display to work with Microcontroller quite some time because i really like the way e-ink display looks. Although many people have done it before but for some reasons there code was not working for me. i have already tired with a my WireFrame FPGA Board but failed for unknown reason. So i decided to give it try i designed a new board to give it Second Shot and i finally managed to get it “work” . this time i am using MSP430FR5739 microcontroller for no particular reason. i just needed a part so i used MSP430FR5739 Because i have used this before in my solar LED project.
This this just quick demo of concept to test if i got waveforms right. as MSP430FR5739 is quite slow and does have only 1KB of sram ,Controlling a 800×600 pixel display is really pain. so i will use some powerfull microcontroller to display rich graphical content on this display.

Figuring out schematic was very easy as there are may service manual available of e-readers . one of them is Sony PRS-505 , i have ordered one old bad battery one from ebay took it apart and good thing about this e-reader there are test points available for every single point we need. Schematic available from my github account with link
Schematic from service manual describe ever test point , so i just soldered few wires to
My schematic has basically no change since FPGA driver board , except VCOM voltage Opamp Circuit. High resolution PDF is available in my github account.
Wave form Reverse Engineering
Image give blow , show a complete screen change. it consist of 38 individual frames .
|One Full Screen change
|one frame (First) from 38 Frames Required for screen change
|Start Of one frame
|Start of One frame Zoomed
|one line writeof 800 pixel
|End of Line Write
PCB As this is just a quick test PCB to test waveforms i have not much on the board on the necessary components which are absolutely required to drive the display and all display pin are available on test points.
