Making Opensource USB C industrial camera with Interchangeable C mount lens, Interchangeable MIPI Sensor with Lattice Crosslink NX FPGA Cypress FX3 USB 3.0 controller



 This post is going yet another part in the DIY camera projects which have been doing since quite some time. In this post I will showing you next successful implementation of making C mount high lens mount  USB C camera. This implementation will have absolute modular boards having dedicated Sensor board which can be changed if needed.

USB 3.0 Camera board with Cypress FX3 CYUSB3014 and Lattice FPGA CrossLink NX LIFCL-40 Prototype

  From quite some time i have been working with different MIPI CSI Camera Solutions , Interfacing Camera with FPGA and Connecting to USB 3.0 Connection. 

Board will be having USB C connector for USB 3.0 5Gbps Connection with Cypress FX3 CYUSB3014 and Lattice Crosslink FPGA

Board With Direct Raspberry PI IMX219 

Board with FCP Connector for Any MIPI Camera With 1mm Flex cable

Agilent Keysight 53220A Universal Frequency Counter Option 010 Ultra High Stability OCXO Timebase Upgrade

 I have previously upgraded Timebase for Agilent/HP 53132A Universal frequency counter and also PM66xx Counter. This time i will be upgrading Keysight 53220A.

This upgrade is going to be little different as keysight 53220A does not have a oscillator module. OCXO is directly soldered to the main board. So this upgrade is just going to be desoldring existing TCXO and mounting correct OCXO to have Option 010 Ultra High Stability OCXO Timebase activated. 





DIY Fluke Philips PM66xx OCXO 10MHz Oven Oscillator option board for PM6680B PM6681

 Quite a while ago I had written about how I upgraded oscillator of my Agilent/HP 53132A. I have recently bought a broken Fluke/Philips PM6680B Frequency counter. Though i was able to quickly fixed issues with the unit by replacing power supply capacitors, the unit still has really crappy original reference oscillator. So I decided to make my own PM9692 Ultra High Stability Oven Time Base with CTS 196 OCXO.

DIY Open Source MicroZed Breakout Carrier Board For MicroZed Zynq FPGA SOM board

For new FPGA SoC related project, and i will be using Avnet MicroZed Zync SOM board. But Avnet microZed Board has two 100 Pin fine pitch connectors for expansion, Which is impractical for prototyping so i decided to make my own breakout board.  Finding Avent microzed GPIO breakout was little hard and official board has same VCCIO regulator for all banks and avnet board also does not have differential LVDS layout.
So i made this Open source Board, With three separate switching regulator for each bank VCCIO on 4 Layer Gold finish board with most of microZed pins broken out in LVDS pair. PCB is 4 Layer impedance control for 100R LVDS pair. Board has 3 solder jumpers per regulator to change bank voltage of each bank separately.

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

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 get data out of MIPI camera, make it useable 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.
