Story

Unique TFT Shield for Arduino Uno. OV7670 camera live video (continued)

Hello! Today's article is a continuation of the previous article. Earlier, I started talking about a unique TFT shield for the Arduino platform. Today, I would like to demonstrate the new features of this shield: I connected the regular camera OV7670 (without FIFO) to the TFT shield and are viewing live video from the camera on the TFT screen. Demo video here. To be continued.

P.S. If you like or are interested in this topic, please rate my article. Perhaps your assessment will speed up the next article. :-) Thanks for attention.

1) Unique TFT Shield for Arduino Uno - Start.

2) Arduino Bluetooth Camera (ABC),

3) TFT shield for Arduino Nano - Start,

4) Photos and RGB video on TFT SPI display.

Update 01.04.2021:

Hello again! There is an updated library for a series of screens, which currently consists of two shields and two breakout boards. The sketch is compiled depending on the selected version (from 1 to 4) and the type of microcontroller (MegaAVR or ESP-32). Added photos, examples. More information can be found in the https://github.com/Ekaburg/EkaTFT.
