AVR web modules
Web address : https://https://www.ulrichradig.de/home/index.php/avr/avr-webmodule
Firmware, source code, PCB & schematics are provided, and documentation.
On that web can be found other very useful projects such is digital scope up to 12MHz, webbox with ARM, ...
Switching Power Supply
4 relays - for switching up to 230V
4 digital inputs - protected by optocouplers
6 analog inputs - each with space for a voltage divider
1-wire reading DS18B20
Uses FiFi Web Server, open source software: https://sourceforge.net/projects/fifi-webserver/
Camera
To operate the camera, we need 14.7456 MHz, while the ATmega644 with 1Mhz overclocked. (In my case it did not reveal any problems, but it should be mentioned at this point.) The hand-held camera Philips DC-3840 is now on the post box connector JP2 are simply connected. When connecting the camera, a DEBUG output via the software simulated UART.
