same here
i made 2 sunrom programmers

and they were working perfect

but after that at the same time the 2 programmers show that annoying message

verify failed at 0

iam using at89c52

i thought that the uc that i use has a failure so i bought new 2 micro controllers but same message occur

then i thought that it is a power issue so i bought the 7815 regulator

so the input voltage to the programmer is approximately 14.5 volt DC

iam working on that problem for a week

so any help is appreciated

thanks in advance and waiting for ur
