Eternyt:
Thanks, but I'm still not able to connect to my chip.
I use this schematic for the voltage conversion from 5V to 3V (where I assume that the non _L pin stands for the Arduino pins, and the pins with the _L in the end are the chip pins):Then I just run the FlashDiagnostic example from the library you linked (without changing anything of the code) and it's no work at all.
What I'm doing wrong here? Thanks!
If you need to talk with a 3.3v SPI device a resistor divider is not recommended.
Has a good discussion. Note the error That is listed in the comment section after the article.
I have used the 25Q64FVS but on custom boards. The TiBackup is a atMega328P running on 3.3v.
The Lifter is with a MEGA2560 running on 5.0v.
On both of these schematics, VDD is 3.3v and VCC is 5.0v
