SPI communication between MSP430G2553 and arduino uno R3

Hi,

I am trying to interface MSP430G2553 and arduino uno R3 via SPI. MSP430 acts as master and UNO is slave. Though data is transferred from master, but its not received at the slave. I’ve not made use of standard library API’s of SPI but I’ve tried to write the code using register names.

Attached is the code of UNO R3. Please review and suggest if I am doing anything wrong.

Thanks and Regards,

I've not made use of standard library API's of SPI but I've tried to write the code using register names.

Why? Perhaps doing it the standard way first would be appropriate.

Well, Instead of resuing the code I want to test my own capability and make it work. This would rather increase my confidence is what I belive.
