INSTALLATION OF THE SYSTEM
When you open the box of the development system, it should contain development system, CD, programmer and a serial cable (LCD, LTC1290, REF02, oscilator 4MHz and temperature sensor DS1820 are optional when ordering the package). Installing the system takes just 3 steps:
Step no.1 The first thing to do is taking the system out of box and connecting the programmer to IDC10 in the upper right corner of the development system. The other end of programmer should be directly connected to paralel port of the computer.
Step no.2 The next step is connecting to the power supply. Power supply can be both AC/DC accordingly. Supply voltage is 9 to 12 V (AC or DC). The picture below illustrates the first contact with the development system.
Step no.3 Installation of AVR ISP software. Run SETUP.EXE in folder
...\CD\ISP or directly by clicking the ISP link on the first page of presentation provided on the CD. After short and simple procedure (answer all the questions with yes) installation is complete.

Step no.4. Clicking the icon
appropriate program. To make detection easier, Intel Hex File option should be selected - the upper left corner of Load File In Buffer window (picture 7.).
Picture 7.
After the wanted HEX or ROM file has appeared, click it and load it to buffer with OK, after which it will be transferred to microcontroller.
NOTE: HEX file can be created using any assembler, BASIC or C compiler.
Step no.5. After successful loading to computer buffer, following picture should appear. Clicking the OK in the File Load window ends loading the program.

Picture 11.
For all the elements in the development system to work properly, it is required to have stabilized +5V. With AVR-easy system, it is achieved by using the power stabilizer LM7805. Because of the increased dissipation which occurs at higher current consumption, stabilizer is set upon the appropriate cooler.

LED DIODES
The system has 32 diodes that are connected to the port 0, 1, 2, and 3 pins. These diodes are ordinarily used in the first phase of the work, but they can be also used for the later indications of the program flow. Each set of the diodes can be turned on and off using the SW3 switch. The way to connect the LED diodes with a microcontroller is shown on the following picture.
NOTE: LED diodes are turned on with a logical zero. It means that a microcontroller must have a logical zero on a pin for diode to emit light.

The mark above every button represents the name of the pin which the button is connected to. In order to use a button, appropriate pin of ports 0, 1 i 3 must be designated the input one. Jumper in the lower left corner of the development system is used to define if the active value of a pin is 0 or 5 V. If the jumper is set to “up”, then activating a certain button will bring logical one to the pin, while “down” position will bring logical zero.

LCD DISPLAY
Standard LCD display (2x16 characters) is supplied. However, it is not a limitation, because any display having the same type of communication with the microcontroller can be used. Display contrast can be adjusted using the potentiometer in the lower left corner of the development system. LCD display can be connected to the port 1 or the port 2. Following picture shows how to connect the LCD to port 1 and the picture 18. how to connect LCD to port 2 of the ATS908515 microcontroller.
