The microcontroller (preferably from Microchip) will have to manage the following:
- OSD interface - black/white graphics (buttons) and text . The LCD is 7 inch 800 x 480 resolution and accept CVBS composite video input only and the OSD must be available with or without the video signal at input.
- 4 wire resistive touchscreen. The touchscreen will use the buttons of the OSD to activate various functionalities.
- 3 bitone ringtones.
- various I/O signals. These I/O are driving other components of this project.
