Facing problem with SPI
I am facing problem with receiving multiple data bytes. I don't know whether the way i have implemented is correct or not.
I have enabled interrupt of SPIs as interrupt on RX_FIFO_NOT_EMPTY.
In the isr i read the no of. bytes received SPIS_ReadRxBufferSize and display the values on LCD directly.
Initially i had set buffer size of 4 and hence i was just able to get only 1 byte of data even on sending 3 bytes as no. of bytes SPIS_ReadRxBuffer was returning only 1(even datasheet says it provides 1).
So I changed to more than 4 bytes buffer. But still i am unable to receive the bytes.
Any solutions ??
