I have been working through the 50$ robot tutorial and, after several attempts, i finally completed the microcontroller. I bought the avrisp2 programmer and downloaded the photovore code, but when i try to program the ATmega8, i get this message:
Reading FLASH input file.. OK
Setting mode and device parameters.. OK!
Entering programming mode.. OK!
Erasing device.. OK!
Programming FLASH .. OK!
Reading FLASH .. FAILED!
Leaving programming mode.. FAILED!
this problem is addressed in this post: http://www.societyofrobots.com/robotforum/index.php?topic=1350.0
but i cant seem to get it to work.
I have been adjusting the isp frequency every time i try to redo it, but i always get the same message
the servos do rotate randomly every once in a while, but they dont seem to be effected by the photocells
all this tells me is that i should have a little hope
someone please help!!
