I think the hardest part of doing it is the fact that without buffering the wifi/ethernet module has to be able to stop everything what it is doing to receive...

It depends on the ethernet module. If the module can receive data over SPI then there probably is enough left-over PIN's to do that (if you remove the display).

Yes, you should be able to detect the brightest pixels and then send their coordinates over the serial line.

Hey! KiCAD project for the PCB is in the "pcb/kaamera_ja_ekraan/" folder of the LiveOV7670 repository: https://github.com/indrekluuk/LiveOV7670/tree/master/pcb/kaamera_ja_ekraan If you want to order the PCB from OSH Park or from one of...

You also need to order two of those 4-channel level shifters: https://www.ebay.com/itm/1-2-5pcs-I2C-IIC-4-Channel-Logic-Level-Converter-Module-Bi-Directional-Arduino/112786869135?var=413225612516&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D49917%26meid%3Dd6a51c4e7ee34f3c8d4315d1f978c733%26pid%3D100005%26rk%3D6%26rkt%3D6%26sd%3D152383209372%26itm%3D413225612516&_trksid=p2047675.c100005.m1851 The PCB is designed to have two 10k surface mount (SMD 1206) resistors (you probably could solder through...

You have to solder the components yourself. There are not that much so solder. It only makes sense to order the PCBs with soldering by the manufacturer if you want...

Reading from the camera is very time critical. Don't you have to share time with WIFI processes? Using FIFO version of OV7670 would solve all the problems here. It also...

Ok, I understand it from the perspective of challenge :) The reason I made the Arduino version was also to prove to myself that it can be done. Specially because...

Have you made any changes in Adafruit_ST7735_mod.cpp? Line 365 in Adafruit_ST7735_mod.cpp is not "void Adafruit_ST7735_mod::startAddrWindow(uint8_t x0, uint8_t y0, uint8_t x1, uint8_t y1)"

Hey! If I remember correctly, then I couldn't get it working myself either. The problem was that UART is too slow. I was not able to slow the camera down...
