Legend: Recommended program (1 to 3 stars)

Crossroad - simulates traffic on a crossroad. The semaphores are controlled by the SIEMENS-SIMATIC CPU212 unit via a serial COM port. Semaphores can be controlled manually, too (no control unit is needed), and so you can become a traffic policeman. Very interesting is to turn off lights and watch neurotically honking drivers.

PicDev - developmental environment for onechip microcontrollers PIC16xxx. The program includes editor, compiler, and disassembler for PIC16F84 processor and compatible. A compiled program can be programmed immediately into the P84-CPU unit of the P84 construction kit, connected via a COM port. Program includes complete constructional recipes of the P84 construction kit, examples of end-applications, and detailed description of the PIC16F84 processors. This system is suitable especially for schools for teaching onechip processors. Most advantage of the system is a very low cost, easy use, and detailed documentation. The PicDev program is a sample of a half-professional application implemented in the Peter system.
