Hi,
all is in the subject
I know I need to to do it ith the icsp port, set the 3V6 jumper open.
I have try with no success:
1vpp >>> 1cs
but I know that the signal must up and down for unlocking read and write (do I need a capacitor or a switch ?)
2vcc >>> 8vcc
3gnd >>> 4gnd
4rb7 >>> 5dataio and maybe 2dataio ?
5rb6 >>> 6clock
Thanks
