Hi!
Welcome Raul!
The new code available on Github is ready to work with PCF8575, no changes is required.
Firstly you should test using an example available on forum to make sure that circuit is ok.
Best regards.

Hi fernando , thanks for the reply I have it working. What happened is that there had connected the pins 20-21 and the TFT screen was bright white.
Greetings and thanks.
