I think we should add this configurations to menuconfig, depending on the ov7725 option

Recently I've been thinking that rebuilding the whole project and the whole IDF each time I want to change camera configuration is not nice. OTOH, it's nice to have stuff configurable from a GUI. Maybe it's time we have a decent web server and configure everything through it? I've been looking at ureq, which is really small and easy to integrate, unfortunately it doesn't really have a way of sending (part of) the data in NETCONN_NOCOPY mode, which is essential when streaming bit chunks of framebuffer.
civetweb (MIT-licensed for of Mongoose) is another nice solution, although might take more time to integrate.
I guess i need to open a separate issue to discuss which embedded web server to use...

how about integrate Jeroen's httpd to this demo, It is quite small and easy to use

Opened #35 :) libesphttpd is certainly an option, but as of now httpSend always needs to copy data into an internal buffer, there's no way to utilize NETCONN_NOCOPY. This way it's either much higher memory use, or lower bandwidth.

Merging this now; will add configuration via esp_console in a separate commit. |
Implements #30
Adds support for RGB565 bitmaps. These can be downloaded as single files or streamed like JPEGs.
