atmega16 clock fuse
I used to use AT90S8535 with bascomAVR then I change to ATMEGA 16
First I try to program it using STK200/300 Compatible isp cable. It program OK But chip ATMEGA16 was work veryslow. Then I read the data sheet it said that default clocksource is internal 1 MHz osc. (I used Crystal 8 MHz) so i need to changed Fuse bit to make it know what clock source is.
Then I changed fusebit using bascom program..
First it say : A987 >> 0001:internal 1 mhz
then i changed to 1010:1010 which follow datasheet for external crystal used.. and i fuse it.....
After it done Programmer can't detect chip any more and can't program it.....
So .. Please help me what i done wrong.. did i gonna loose my ATMEGA16 and if i get new one how can i config it.. Thank....
