This project aimed to support MIPI or DPI I/F off-the-shelf LCD/TFT display.

Expected FPGA Support

1) Xilinx - 7 series (Currently tested on Kintex 7 & Artix 7) 2) Xilinx - 6 series (Currently tested on Spartan 6) 3) Xilinx - Ultrascale+ / Ultrascale (Currently tested on ZYNQMP) 4) Altera - Cyclone IV (🔜 working on hardware) 5) Altera - Cyclone V (🔜 working on hardware) 6) Anlogic - EG4 series (🔜 working on hardware) 7) Anlogic - DR1 series (🔜 working on hardware)

a) In the follow examples, Xilinx 6 series, 7 series, ultrascale+ series should able to support as much MIPI display as possible. b) Xilinx 6 or 7 would require resistor network to convert LVDS to SLVS. c) Successful cases are demonstrated on three Xilinx FPGA families “Spartan”, “Kintex”, “Artix”, and “ZYNQ Ultrascale+”. d) It is confident to say this pure Verilog-based MIPI DSI design is stabled and matured enough to merge onto any FPGA with serialization feature.

Read First !

Please study the example 5.5” LCD with LCD driver HX8399C.

This example provided detail resistor-network vs MC20902 design, which is aligned with Xilinx doc. “XAPP894”.

The resistor-network is not re-simulated via IBIS simulator, so if you really concern on SI then do it as your will.

Commonly Asked Questions

1) Q: Do this design only work on Xilinx 7-series? A: There are example in Ultrascale, and other non-MIPI DSI supported FPGA brand tested internally. 2) Q: Why there are no brand xxx FPGA given? A: Because either the brand xxx either I don’t have it or it is tested internally but not worth to recreate new repositories. 3) Q: Can brand xxx FPGA support 1080p, 2k, 4k etc A: If you understand how MIPI-DSI video mode works, this question won’t even exist from first place!!! 4) Q: Can this Verilog-based HDL design work on brand xxxx. A: Very high chances, because the inherent design don’t rely on IPs nor any DPHY, it is pure MACROs and HDL.
