| To write an AVR program, a project must be created which contains all the necessary files: source codes, header files, compiled program, etc. To clearly seperate projects, a folder for each project should be made (this option is given by the project wizard also). | To write an AVR program, a project must be created which contains all the necessary files: source codes, header files, compiled program, etc. To clearly seperate projects, a folder for each project should be made (this option is also given by the project wizard). |

| **3.** Next, the project must be configured for Homelab kit. From the //Project -> Configure Project// menu open the configurations window and select //Common// tab. CPU type should be ATmega128 and the clock should be 14745600,0 Hz. Also the names of the HEX and MAP files should be specified. Pressing a //Set as default// button makes these configurations as a default for new projects. This is reasonable when working only with Homelab AVR microcontroller. As the HEX and MAP files are also stored as a default it is recommended to use some general name for them, for example "out.hex". | **3.** Next, the project must be configured for HomeLab kit.

| **4.** Seadistada programmaatori sätted, valides menüü //Project -> Configure Programmer//. //Choose Programmer//-kaardil valida AVRDUDE ning AVR DUDE kaardil määrata programmaatori tüübiks //jtagmkI// ja ühendusliideseks eelnevalt leitud port ///dev/ttyUSBx// (vt programmaatori peatükki). Määrata ka siin seadistatud parameetrid vaikimisi säteteks. | **4.** Configure the programmer by opening the configurations window from the //Project -> Configure Programmer// menu. Choose "AVRDUDE" as a programmer. On the "AVRDUDE" tab set the programmer type to //jtagmkI// and connection port to ///dev/ttyUSBx// (where "x" is the port index). Set these configuration settings also as a default. |

| **5.** Seadistada tekstiredaktori sätted nii, et tabulaatorit tõlgendataks 4 tühikuna. See on vajalik, kui juhtutakse lähtefaili avama mõne muu tekstiredaktoriga, mis tõlgendab tabulaatorit teisiti kui KontrollerLab. Sel juhul võib koodi liigendus muutuda, nii et inimese jaoks on kood raskesti jälgitav. Selleks, et seda ei juhtu, valida menüü //Settings -> Configure Editor// ja avanenud aknas vasakult Editing. Märgi linnuke kasti "Insert spaces instead of tabulators" sisse. Samuti määra tabulaatori laiuseks 4 tühikut. | **5.** At last, place the windows in the KontrollerLab as it is more convenient and get ready to write your first program. |

| ===== Seadistuste testimine ===== | ===== Writing and testing a program ===== |
| |
| Kui arenduskeskkond on esimest korda paigaldatud ja seadistatud, on mõistlik testida, kas kõik sai tehtud õigesti. Selleks on lihtsaim viis teha üks väike programm, see ära kompileerida ja laadida kontrollerisse. | After the configurations steps are done, it is time to programm. |
| |
| **1.** Ühendada programmaator ATMega128 Kontrollerimooduli plaadiga. Kontrollida, et programmaator saab ühendatud õigesse pistikusse (JTAG) ja õigetpidi (kaabel on suunatud kontrolleri plaadist eemale - vaata järgmist pilti). Pärast programmaatori ühendamist ühendada kontrolleri toide (kontrolleri plaadil peab süttima väike roheline LED). | **1.** Connect the programmer with Controller module. Double-check if the programmer is correctly connected with a JTAG socket. The cable must head away from the board (look at the picture). Now connect the power supply and check if the green LED lights on the Controller board. |

| |
| **2.** Sisestada lihtne C-kood ja kompileerida see (//compile//). | **2.** Write the following program in the Kontrollerlab file editor window and compile it: |
| |
| <code c> | <code c> |
| int main(void) | int main(void) |
| { | { |
| // Viigu PB7 seadmine väljundiks | // Set pin PB7 as an output |
| DDRB = 0x80; | DDRB = 0x80; |
| | |
| while (true) | while (true) |
| { | { |
| // Viigu PB7 inverteerimine | // Inverting pin PB7 |
| PORTB ^= 0x80; | PORTB ^= 0x80; |
| hw_delay_ms(500); | hw_delay_ms(500); |

| |
| Veendu, et väljundaknasse tuleb teade "File compiled successfully". Kui annab teate "Error(s) occurred: ", siis kontrollida, et koodi sisestamisel ei ole tehtud mõnd kirjaviga. | Make sure that the output window shows "File compiled successfully" message. If the "Error(s) occurred: " message is shown, check the program code for mistakes. |
| |
| **3.** Koodi pealelaadimiseks valida //ignite// käsk. Kui kõik õnnestub, siis väljundaknas viimase reana annab KontrollerLab teate "Project built and uploaded successfully". Kontrolli, et punane LED hakkaks perioodiliselt vilkuma (500 ms põleb, 500 ms on kustund). | **3.** To download the program into the Controller press the //Ignite// button. After the succeful download, the "Project built and uploaded successfully" message should be shown. |
| |
| Kui LED vilgub, nii nagu eespool kirjeldatud, on tarkvara paigaldatud edukalt ja esimene labor läbitud. Palju õnne! | If everything was done correctly the red LED on the Controller board should blink periodically, with 1 second interval. |
| |
| ===== Ujukoma-arvude kasutamine ===== | ===== Using floating-point numbers ===== |
| |
| Mõnikord tekib vajadus AVR programmis kasutada ujukoma-arve. Nendega arvutamiseks ja nende esitamiseks //printf//-tüüpi funktsioonidega tuleb projekti seadistustes teha järgmised muudatused: | Sometimes it is neccessary to use floating-point numbers in program. To calculate with them and use them with //printf//-typed functions, some modifications in project configuration must be done: |
| |
| **1.** Avada projekti seaded menüüst //Project -> Configure Project// ning valida //Linker// kaart. Märgistada //Linker flags// sektsioonis esimene linnuke (vaata ka juuresolevat pilti). | **1.** Open the //Project Configurations// window and the //Linker// tab. Check the first line in the //Linker flags// list (look at the picture). |

| **2.** Vajutada //OK// ja sulgeda seadete aken. | **2.** Press //OK// and close the window. |
