I wonder what conversion would be required between the USB-c interface and the e-ink display?.The better option is probably to use the I2C on the pogo pins to send some basic information to be shown to a small microcontroller, and have that microcontroller compose the graphics and send them to the e-ink display over SPI.
Why better ?
Because :
- The e-ink display has a non standard SPI interface. With a FPGA, this is not a problem. With a micro-controller, you have to write weird code.
- With some Lattice FPGAs, you can initialize/update the FPGA code through the I2C interface. No need to program the board with a specific tool.
- One program to maintain.
