Glider: Open-source Eink monitor with low latency (including detailed explanation of Elink principle)

The author not only shares information about the project, but also shares almost everything the author knows about Eink in detail, given that it is a bit difficult to gather information about Eink online. Project Features:Complete solution for low latency/high refresh rate EPD monitorsSupports electrophoretic display panels with parallel I/F (Eink(R), SiPix and DES)Supports color screens based on monochrome and color filter arrays (such as Kaleido(TM))Extremely low processing latency <20 usSupports binary, 4-level grayscale, 16-level grayscale output modesLatency-optimized binary and 4-level grayscale drive modesMixed automatic binary and 16-level grayscale drive modesControllable region update and mode switching during host software runtimeHardware Bayer dithering, blue noise dithering and error diffusion dithering without additional latencyController natively supports FPD-Link (LVDS), DVI (TMDS) and MIPI-DSI inputBoard-level design supports USB-C (USB Type-C DisplayPort Alt Mode) and DVI inputHardware Description:Xilinx(R) Spartan-6 LX16 FPGA running CasterDDR3-800 frame buffer memoryType-C DisplayPort Alt-Mode video input with onboard PTN3460 DP-LVDS Bridge or DVI (via microHDMI connector) video input with onboard ADV7611 decoderEpaper power supply with up to 1A peak current on +/-15V rail, supports large panelsVCOM kickback voltage measurement supportOnboard RaspberryPi(R) RP2040 microcontroller for USB communication and firmware upgradesProcessing rate up to 133MP/s with jitter enabled, >200MP/s with jitter disabledThe board was designed using KiCad.
