Saeco Stratos problem

[ksb]

Hello Alexallex,
the controller needs a delay while powering up to insure proper work. So a direct connection to 5V would not work. Is there a delay at pin5 before changing from 0V to 5V after power up?
Best regards

The voltage is rising gradually from 0 to 5V (4,97V) in aprox. 1 second.

Hello again. I have bought from aliexpress the TMP87PM40AN CPU, which I believe is the problem here (I think it's fried). The CPU I have bought is empty, so can anyone help me with the program to write it? Also some step by step instruction will be welcomed.

Hello Alexallex,
i fear that nobody could provide this program because the chip is protected.
