Hi Metal slug 2
1) The .hex file will be the product of your code after building it. It will be stored on the same folder where you've extracted it all the things you got from photovore_v1.zip. The makefile will be on this same folder.
Once you have the correct files on place here's what you do...
a.) click "Rebuild All" in the "Build tab"
b.) verify that you have "Build succeeded with 0 Warnings..."
c.) since you have the MKII click on the AVR icon select the "AVRISP MKII" on the left and USB on the right of the window that popped up.. click on "connect"
d.)select atmega8 in the device field.
e.)set Programming mode to ISP check the two boxes (i.e. Erase and verify after programming)
f.) on the Flash Programming area select "Input Hex file" then browse for your Photovore_v1.hex by clicking on the ... icon (this file as metioned earlier will be on the folder where you extracted the .zip file example c:\My_Robots\Photovore_v1\)
g.) now click on the program button on the Flash area (of course your MKII must be connected to your atmeag8 and the circuit powered-on at this point).
Hope this helps. If you still bump into troubles just keep on posting.

delay_cycles(cycles);
Delays - you can make your robot wait for a certain amount of time with this function.
Put the number of computational cycles to delay in the ().
23 cycles is about .992 milliseconds
to calculate: 23/.992*(time in milliseconds to delay) = cycles
Check servo datasheet where it says: 'Direction: Clockwise/Pulse Traveling 1500 to 1900usec'
servo_left(speed); and servo_right(speed);
Commands your servos to rotate at a certain speed.
Vary speed (which represents a delay in cycles) from 20 to 50.
Left is for port D0 and right is for port D1.
LED_on(); and LED_off();
Turns on and off your LED. The LED is on port D4.
By bringing port D4 low, you are turning on the LED.
variable=a2dConvert8bit(pin);
Reads analog pin. For example, set 'pin' to 5 to read PC5.
'variable' will store the value.

OK heres what i do, and its not working, maybe theres something I'm doing wrong(obviously):
1. open avr studio 4 and crate a new project: 'Test_Stuff' and select AVRISP mkII programmer with the ATMEGA8 mcu.
2. copy everything (except the Photovore_v1.aws files) from the Photovore folder into the Test_Stuff folder.
3. copy the photovore_v1 source code to the Test_Stuff.c source file which was initially created
4. mod the source code with what "g" posted earlier
5. now i click Project>configuration options and a box opens up.
6. i click 'use external makefile'
7. THIS IS WHERE IM CONFUSED: when i look for the makefile, i find two: one in the Test_Stuff folder with all the other copied stuff from the photovore folder and another makefile found in the 'default' folder found in the Test_Stuff folder (Test_Stuff/Default)(why is that even there?). i choose the one found in Test_Stuff the and click 'OK'.
8. i click Build>Rebuild All
9. THIS IS WHAT I DONT UNDERSTAND: everything compiles OK, but on the 'messages' thing theres a red dot and a message saying:
gcc plug-in: Error: Object file not found on expected location C:\Users\Dustin\Desktop\Robots\AVR Studio Robotics\Test_Stuff\Test_Stuff.elf
Make sure your makefile specifies the output .elf file as Test_Stuff.elf
10. it says something about the makefile..so i open the makefile up and find this:
# Target file name (without extension).
TARGET = Photovore_v1
i notice that the targets name is Photovore_v1, yet my code is called Test_Stuff, so i change Target to this and save the Makefile:
# Target file name (without extension).
TARGET = Test_Stuff
11. I redo step #7, nothing happens, i redo step #8
12. This time i get 4 errors and the previous message statement:
Test_Stuff.c:58: error: 'count' undeclared (first use in this function)
Test_Stuff.c:58: error: (Each undeclared identifier is reported only once
Test_Stuff.c:58: error: for each function it appears in.)
Test_Stuff.c:90: error: expected declaration or statement at end of input
13. it seems count variable is undeclared, so i add a count variable
14. i rebuild and everything builds fine, however, under messages i still get this error:
gcc plug-in: Error: Object file not found on expected location C:\Users\Dustin\Desktop\Robots\AVR Studio Robotics\Test_Stuff\Test_Stuff.elf
Make sure your makefile specifies the output .elf file as Test_Stuff.elf
even after i renamed the makefile for Test_Stuff..........
15. I ignore that message and experiment. I redo steps #7 and 8 then hit the little avr button to program the device. this time i actually find a Test_Stuff.hex file
I load it up and download it to my $50 bot.
16. It works!!!!!
...but theres only one problem...it runs forever...what I'm aiming at is a simple program which will move the servos for lets say 5 seconds in one direction, stop, then move in the opposite direction for 3 sec. then moth move in different directions for 2 sec. etc. but i cant for the life of myself figure out how to do it...
help would be very gladly appreciated because i simply can't get this thing figured out
