Why SPI Communication not working properly?

[Anonymous]

Hello Every one,

   

I am making a SPI master slave test program with certain conditions:

   

I want to do the following:

   

Master is sending an 8 bit data in order to start the communication.

   

At the same time slave will directly send some dummy value.

   

Then: if the master has send a value 0x02 then the slave should send 0x10u.

   

otherwise it will give 0x58u.

   

I write the program (please have a look at the attachment). But, some how its not working as it supposed to work! there must be something wrong.

   

I will look forward to hearing from you.

Please go through the component datasheet properly and see the API explaination too.
