. It will ask you if you want to begin a new project, or open an existing project.

Choose Cancel and click on the connect icon.

It will open a new window with a connection dialogue asking you to select your programmer andconnection port. With a programmer like the AVRISP mkII it is easy because when you select thatprogrammer it brings back only one choice of port... USB. The AVR-ISP500 from Olimex isrecognised as a STK500 and has the option to auto choose the port. If it fails to recognise the port,you may need to manually set the port for the programmer in your Windows device settings toCOM1 up to COM4 for A

VR Studio to recognise it.

When you have chosen your programmer and port, click connect and you will be taken to the AVRprogramming dialogue.

In the AVR programming window go to the "Main" tab and make sure that the chip you areprogramming (e.g. Atmega168) is selected in the "Device and Signature Bytes" drop down menu.Also make sure that the" Programming mode and target settings are set to ISP. Make sure that thesettings for the ISP mode have the ISP frequency set low enough to talk to the chip. I set my AVR-ISP500 programmer's frequency to 115.2 kHz. This is quite an important setting to get right. If youclick on "Read Signature" and you get the response "Signature matches selected device" you have

successfully managed to connect to your IC.

Also make sure that the target board or PCB is powered (You can check this by clicking on the HWSettings tab and checking if the programmer can see any voltage).

Now it is time to set the fuses so click on the "Fuses" tab. AVR Studio is very good in this respect asit will work out the fuse settings for your particular IC depending upon the check box options you

choose.

Set the check boxes according to the following. SELFPRGEN: uncheckedRSTDISBL: uncheckedDWEN: uncheckedSPIEN: checkedWDTON: uncheckedEESAVE: uncheckedBODLEVEL: Brown-out detection at VCC=1.8 VCKDIV8 : uncheckedCKOUT: uncheckedSUT_CKSEL: Int. RC Osc. 8 MHz; Start-up time PWRDWN/RESET: 6 CK/14 CK + 65 ms

The fuse setting output will be displayed at the bottom of the window.

Check the "Auto read" "Smart warnings" and "Verify after programming" options at the bottom ofthe window and then click program. If all goes to plan, you should get OK response messages in the output section at the bottom of yourwindow for Entering Programming mode, writing fuse address, reading fuse address, Fuse bits

verification and leaving programming mode.

If you get error messages, then recheck your chip version and all the connections from yourprogrammer to the board and that the power is on. Also make sure that your fuse settings are asdescribed above.

Flash the Firmware

Click on the "Program" tab and have a look at the "Flash" section which is the 2nd section down.Check the "Input HEX file" check box. Then browse the unzipped firmware folder and click onyour firmware HEX file suitable for the chip you are programming for an Atmega168. Then click"Program" in the Flash section of the window and you should get an OK response in the outputsection at the bottom of the window. Then click "Verify" to make sure that the program has beensuccessfully uploaded and if you have an OK response coming back at the bottom of the window

then you have successfully programmed the IC with the test program.
