Opens Source IMX219 Camera MIPI CSI-2 Receiver Verilog HDL Lattice FPGA MachXO3 Raspberry PI

This post is going to be yet another part of the previous camera projects published on this blog. As described in the last post here in which i made Raspberry PI camera Sony IMX219 4 Lane MIPI CSI Board.

 In this post will be having details about how to what is needed to Get data out of MIPI camera and then feed data into Cypress FX3 USB3.0 controller.

DIY IMX219 4 Lane MIPI CSI Breakout Board, Getting MIPI CSI 4 Lane From Raspberry PI Camera

I have published many post in which i have been interfacing various cameras sensors/modules to different processors. This post is also going to the next part the previous posts.

Currently i am trying to interface Raspberry pi camera V2.1 sony IMX219 Camera to Lattice FPGA  then ultimately to USB 3.0 with Cypress FX3 USB 3.0 controller.

As per schematic of Raspberry pi and Raspberry PI Camera module. It is two lane MIPI CSI Camera Board with 1 Clock and 2 MIPI CSI data lane.

DIY USB 3.0 1080p Full HD Camera with Auto Focus and 10x Optical zoom, 1Gbps Streaming Over Cypress FX3 USB3.0

This Project is also going to be next in the series of post i made about interfacing various camera modules to processors and Over to USB.

In this post i will be using powerful cypress FX3 CYUSB3014 USB controller board to interface PE1005 Camera module to USB 3.0. This post will overcome the limits imposed by OV7670 in the last post. OV7670 was just a VGA camera. but PE1005 is full HD 1080p 30PFS camera module with really nice features like Auto focus, 10x optical Zoom, F1.8-2.2 Mechanical Shutter. Electronic image stabilizer.

This camera module is from company called Acutelogic HK limited i received this camera from a eevblog forum member a while back.

Open Source USB Display: SPI MIPI Bridge with FPGA Test: PIC32MZ USB HS SPI Bridge QT5

This post is going to be second part in the SPI MIPI Bridge. In this post i will be giving details about USB HS to SPI Bridge  To feed into FPGA for displaying on to MIPI LCD. Previous project SPI MIPI Bridge can be found here.

Open Source SPI MIPI Bridge with FPGA: Driving IPOD Nano 6 MIPI LCD Using FPGA, MIPI LCD Reverse Engineering

As display technology is advancing, High Resolution LCD/TFT LCD panel are becoming more common. With higher resolution comes nicer picture quality, rich content with higher bandwidth requirement to transfer that content from the display controller to the display it self. Gone those days of 8-bit parallel bus , now MIPI is becoming more and more common with nice display.  Yes one can still buy parallel or lvds interface display. But as one try to move towards nicer quality display MIPI is becoming dominant. Basic MIPI DPHY can achieve 1Gps per-lane with mipi DPHY V2.5 you can go upto 6Gbps Max total bandwidth.



This post going to be about how to use FPGA to drive a MIPI LCD. Specifically LH154Q01-TD01 LCD This is a 240x240 1.54 inch TFT LCD this LCD is used in Apple IPOD nano 6G. I first get to know about this LCD from mike's post on his website mikeselectricstuff and youtube channel. It is highly recommended to got through it if you are going to implement this project.
