# TTGO demo
|
|
|
|
This demo purpose is to see the cross-compiled OpenCV library working on the TTGO module (see https://github.com/Xinyuan-LilyGo/esp32-camera-screen), using an OV2640 camera and an LCD.
|
|
|
|
The demo gets an image from the camera, then depending on the DisplayMode (changing at regular interval), applies a Grayscale, Binary or Canny filter on it and finally displays it on the LCD.
|
|
|
|
|
|
|
|
|
|
|
|
The performances of the processing are approximately:
|
|
|
|
* 6 fps with RGB565 image
|
|
* 6 fps with Grayscale image
|
|
* 6 fps with Threshold transformation
|
|
* 3 fps with Canny detection
|
|
|
|
|
|
|
|
The size taken by the application is the following:
|
|
|
|
```bash
|
|
Total sizes:
|
|
DRAM .data size: 33536 bytes
|
|

|
|
Used static DRAM: 107960 bytes ( 72776 available, 59.7% used)
|

|
|
Flash code: 1 096 883 bytes
