no output from avr ports
i'm using atmega 8535...
my minimum system avr is used to fine..but now its jams
in my minimum system avr, my microcontroller can programed but there is no voltage output...
to check the problem,i use simple program that only give all port high (255)
but still there is no output...(all port still low)...
i suspect that microcontroller is bad or clock from crystal doesnt good...
but already change microcontroller and use internal clock but still jams....(all port still low)
use the same microcontroller and same program to another minimum system..its works fine...
can anyone help to solve this problem...
thx b4
