Design an automaic traffic light. When the traffic light does not detect a vehicle (using infrared transceiver), the traffic light (RGB LED) will continuously display RED.When a vehicle is detected, the traffic light will blink RED 3 times. before turning to GREEN. By the time it is GREEN, the 7segment DSP1 and DSP2 will display '10' and counting down each second. By the time the counting reaches 5, the traffic light turns form GREEN to YELLOW. The YELLOW will blinks each second until the count reaches 0 and turns RED.

This is the code by MiniIDE software? using Dragon 12 board?. I need the code by codewarrior in c language? or assembly language that do the same thing with dragon 12 plus board. Thank you !
