This is an follow up For the previous post in which i demonstrated how you can drive kindle E-ink display with a microcontroller.
previously i was using a MSP430FR5739 , which is really low power mcu but has very little RAM and a bit low speed to do anything related graphical on it.E-ink has 800x600 pixel resolution so it required minimum 60Kbyte of RAM to store Frame Buffer. although you can easily getaway without frame buffer by directly doing incremental drawing on to screen but there are few issue in that because of the way E-ink display works. one more issue with there with MSP430 , it has very low program memory so we need some sort of external memory to store font data and icons.
so i have decided to use PIC32 microcontroller , PIC32MX795F512H to be exact. which has enough of ram and flash can go up to 80Mhz. which is more than enough for our purposes.
