nrf to slave device

[Sadasivam]

Sir, I have interfaced nrf board(Master) with msp430(slave) device through spi communication. And Everytime when i am debugging, i got different data(ie,. data which was sent from nrf is shifted by one bit in msp rx_buffer). And also, in nrf rx_buf allocates only the last byte for every array elements. Please give me some suggetions regarding this issue. My connection is as follows:

nRF52832 to MSP430(eUSCI_B0 MODE)

P0.03(SCK) to P2.2(SCLK)

P0.04(MOSI) to P1.6(SIMO)

P0.28(MISO) to P1.7(SOMI)

P0.29(CS) to P1.3(STE)

Hi,

Looks like you are running into erratum USCI40 on the TI chip. Here is a post where a user had a very similar problem with the MSP430. Take a look at the comments there.

Hi Sir,

I have changed the configuration settings in nrf regarding Clock Polarity and Phase. Now the data out from nrf to msp is receiving properly. But for receiving the data from msp430, it is difficult to get the data. Is there a seperate configuration for receiving data also in nrf

[Sigurd]

What do you mean by "it is difficult to get the data" ? Are you receiving any data ?

Yes Sir, finally i got the data. Simply clearing the spi bus line is needed for good code. And I changed the clock polarity and phase as same for both master and slave. Thank you Sir, for your support.
