Hi,

I try to activate SPI connection with EEPROM, but I think that I doing something wrong.

I initialize ST as master, and send write instruction to slave, and after I send read instruction but nothing happened.

Before all instruction I low Chip Select pin, and high after. Somebody have example how to use SPI correctly.

Or may be somebody can explain me a bit about MSB and LSB bits, and CPOL and CPHA, that 2 issues that I can’t understand.

Thanks a lot,

Vlad
