For the spi mode CPOL = 1 and CPHA =1 does the master(stm32f103 controller) receives data on MISO line at the rising edge and also sends data on the MOSI line at the rising edge? Similarly for the spi mode CPOL =0 and CPHA = 0 does same happen as fo...

1)The IC supports both the modes of SPI(CPOL =1,CPHA =1 and CPOL =0,CPHA =0). On the master side I have configured the SPI with CPOL = 1and CPHA = 1.2) According to this master SPI mode the master will receive data at the rising edge and the slave se...

Hi, Iam using a m95080 eeprom IC. Iam not able to read any data from it. Foolowing are the steps iam doing:1) Doing a low on chip select.2) Sending a Write enable instruction to ic(0x06).3) doing a high on chip select.(This should set the write enabl...

Kindly provide me with the software driver files of m95080 eeprom ic.

Hi, Thanks for the reply. The delay that i mentioned is not there when i change the master mode from CPOL = 1 and CPHA = 1 to CPOL= 0 and CPHA = 0(which is quite surprising as these modes are almost same).The main problem that I have at the moment is...

Ya actually I looked into it. But I was trying the very basic instructions on the eeprom IC first just to make sure its working fine and the connections are all intact.Thanks.

That's correct. I will check on the IC and the connections. Thanks a lot for your response.

As I mentioned I tried with 5 millisecond delay. The steps that I mentioned above are in correct order right or should I change something in there?I will check the connections. Thanks a lot for your response.

Hi,Yes I tried by giving a delay of millisecond between step 3 and 4 but still getting the same data(the data I sent on MOSI line 0x06 and 0x05) on MISO line

Im working on stm32f103 controller which has an eeprom interfaced to it via spi.

Hi, I'm using EEPROM M95080. It is mentioned that the IC will send data at the falling edge. But its not happening exactly at the falling edge(there is a delay of almost 0.2 microseconds after the falling edge).
