Yet Another OV7670 Cam to LCD with some differences...
Posted: Sun Sep 30, 2018 4:02 pm
Hi
Release of my latest project:
I now send camera pixel data directly from the OV7670 to my LCD screen, so the pixel data bypasses the ESP32, and
I don't need to use ESP32 I2S or DMA. The ESP32 has to coordinate everything.
My demo is at 25 frames per second at 320x240. And the LCD has a touchscreen, so we can tap on the screen to take a
snapshot of the current image. The ESP32 then reads the pixels from the LCD framebuffer and uploads them (currently
slowly, over serial) to the host computer. So I can capture 320x240 images to my laptop.
There is a two-minute demo video at https://www.youtube.com/watch?v=3Ga8L9qx-Yk, and the source code and
writeup is on github at https://github.com/cspwcspw/ESP32_YetAnotherCamToLCD.
Enjoy.
