I was told to do some project for my microprocessor class mini project

which is about carpark system simulation using wookie and winbug

basically what the lecturer wants is a system like those that you see in carpark.

Lets say there are 9 lots available in the carpark, the first car enters and as the sensor reads it deduces one lot so it is left with 8 and then the next car is to cum along and as it hits the sensor it goes to 7 lots and so on until the there is no more lot, the program should show FULL on the LED.


I got the program, but i could not display my numbers correctly on the LED as i touch the sensor with the card(which represents the car) then it changes to FULL on the LED.

this is the program hope some one can help, this is not a C++ program but hope someone can help me.
