Joystick

A joystick as we can found PS-2 extension for players is provided near the LCD. With X & Y analog movement it could be use for games on the display or to control the Pan Tilt system with camera.

The connector is 5 pins, +5V powered.

R between Vcc and Gnd = 4 k

The resistors are 10k. The idle position is Vcc/2.

The 2 analog outputs are connected to an ADC with SPI connection to the FPGA: MCP3204T

The ADC has 4 input, 2 Joystick modules are connected to one ADC chip.

The ADC converter is connected through the SPI interface.

PAL camera

The small camera is mounted on the Pan tilt and the PAL output is decoded by a video decoder TW9912 from Intersil.

The output is a digital stream in YCrCb format 4:2:2.
