I'm following the $50 robot tutorial, and have come apon a slight problem. I'm using an ATmega168, which from reading other posts, doesn't need any changes in the wiring, only a couple of changes in the makefile. I'm also using the AVR ISP2 programmer through AVR Studio, which tells me the ATmega168 is programmed correctlywhen I load the hold_servo.hex file:
Getting isp parameter.. SD=0x3e .. OKOK
Reading FLASH input file.. OK
Setting mode and device parameters.. OK!
Entering programming mode.. OK!
Erasing device.. OK!
Programming FLASH .. OK!
Reading FLASH .. OK!
FLASH contents is equal to file.. OK
Leaving programming mode.. OK!
My problem is that there is no output to the servos on the D pins. I've tried to read the output with a multimeter, via the ground line and the power line, but the is no reading at all. I'm 90% sure I have no shorts in the cicuit, so does that mean I've blown the microcontroller, or that the 10% that I'm unsure about the short is correct.
Thanks in advance for any help. BTW love the site!
