Dear all,

I am using SPI to read and write to EEPROM(m95512), but I read result is 0xFF using the following interface :

SPI_MasterTransferBlocking(&spi_motorInstance, &cmd[0], &rec, 1, 1);

Hi,

- what do you see on SIN pin, is there different value sent from EEPROM? Can you share signals you have on SPI bus?

- what is the status returned by SPI_MasterTransferBlocking function?

- last parameter is timeout (in ms), you can try to extend it.

BR, Petr

Thank you. I have resolve to this problem. It need to wait a few times between two frames to send.
