Hello friends, I have been reading the instructions well, I thought I was roasting the microprocessor badly.
The story is that it is a project of my Father, he is 65 years old or older. XD, he bought it to do the V2. and also the minimum project with which I am now helping you. Today I discovered, after coming from fk!$ the doctor, :) the problem, the female din5 connector, you only have 1, 3, 5 pin. I could never get in touch with the core, maybe wireless. Tomorrow, if my ankle allows me, I'll go find a din5 with all the pins. Sometimes we look for problems where they don't exist. Just putting the oscilloscope on pins 2 and 3 of the octo was enough to see that there was no sign of a signal.
Tomorrow I will tell you how it is, I am very grateful for your comments.
