使用RTX51 TINY实现的proteus仿真例子traffic（交通灯）

Traffic is a program that controls a traffic light. The traffic light is timed and lets cars pass during a specific time period. There is a pedestrial crossing button that lets pedestrians cross. The lights are connected to Port 2. You can see this in action using dScope. There are several things of interest here: * This program uses RTX51 Tiny. Program initialization and operation code are in TRAFFIC.C. Look for the init task to see where everything starts. * Serial I/O is interrupt and signal driven. Look at SERIAL.C for the complete, encapsulated module (you may want to use this in your programs). The TRAFFIC program is available in one target: Demo-Simulator: for eval tools in SMALL model for Simulation Simulator: for full tools in SMALL model for Simulation MCB900-RUN: for MCB900 Eval Board in RUN Mode EPM900-Emulator: for EPM900 Emulator for target testing The configuration file Conf_tny.A51 disables the round-robin timeout and enables the CPU idle mode. Notes: - The target Demo-Simulator allows program run with Eval Tools. - The target Demo-Simulator loads a fixed program image that cannot be modified. - The remaining targets (Simulator, MCB900-RUN, EPM900-Emulator) require a full version of the Keil C51 Tool Chain.
