MIPI CSI based development kits overview

those image sensors for webcam applications are highly integrated, and can be connected to PC via USB, eg OV7725 vga



Sony image sensor interface is using sub-LVDS, sort of bridge circuitry is required to convert to MIPI CSI protocol


sensor bridge:

Lattice   various solutions, eg  MachXO3   ,$25




Lattice FPGA Mach project


IMX219 running on 4 lanes with MachXO3



Xilinx Virtex(very high performance), Zynq(64 bit controller + FPGA)







Xilinx appnote






Epson S2D13P04 ( details to be added )





btw, HiSense 3516 series are image sensor SoC which encodes videos in H.264 , H.265 formats, not really intended for raw image or videos

System level:

Cypress EZ-USB CX3, with USB3 interface

eCon e-CAM130_CUTK1 connecting to a Tegra K1 board via 4-lane MIPI CSI-2 interface:




Texas Instruments DaVinci imaging processor with Lattice sensor bridge:






Raspberry Pi and clones eg banana Pi/Pro(Allwinner A20), OrangePi, Odroid,....

NB: The camera module from Raspberry Pi has a crypto chip, and device driver is closed source.
Anyways, Raspberry Pi was not started with totally free open source. The boot codes were not open source either. It just claimed to support linux kernel and Debian based systems, eg Raspbian.

Nvidia Jetson TX1 


this Tegra K1 ARM is more powerful than Snapdragon 805, and have 3 MIPI

calculate pH of phosphoric acid

Question: adding 1/4 teaspoon of 10% phosphoric acid  to 19 litres of water, what will be the pH? Let's go through the calculations step by step. Step 1. Convert mass ( or volume) of 10% phosphoric acid to mole per litre ( mol/L) The above calculation shows that 1/4 tsp of H3PO4 acid is 6.97e-5 mol/L Step 2. Input this value to BATE (or other app) to calculate pH The answer: pH = 4.16, ie too acidic !? If you use pipette instead of teaspoon,  1 drop = 0.05ml. So 1/4 TSP means roughly 25 drops If you actually aim for pH 5.6 (which is optimum pH for mashing), conc will be 2.51 e-6, or 1/100 tsp , 0.044 ml, roughly 1 drop Let's roll back a bit. From  recipes of   BarleyWine , summer rye , hefe Gordon Strong suggested to use 1/4 teaspoon of 10% phosphoric acid, which is targeting pH of 5.5..... Discussion on  homebrewtalk  forum. However using online BF water calc , Sparge pH would be 4.6. but he also added 1 tsp of CaCl2. 2H20. Mash pH change from 5.7 t...
