hi
i have a programmer board which i used to worked with it correctly.
model : stk500
but now any chip i want to program it gives the error like:avrisp error leaving programing mode
back then , when it worked if i didn't put any chips on the board a led would trun on before it warns me that there isn't any chips
by the way this program has to methods to program an avr chip: 1) to put the chip on the board of programmer 2)use a cable to program it on the circuit(i think it is isp method as it stand for in system programming)
and before this happens the second method didn't worked(about a week ago it worked)
any help would be appreciated
