Concatenating arrays

[Wayne_]

I have the simplified Physical Layer Spec but there is no timing information for the SPI bus/data. I am also having problems due to the lack of this information with regards to my own code.

I have now got SPI DMA on the 18F46J50 to work but I am having to force the SDO2 line high by sending an spi_write2(0xFF) before sending a command because the SDO2 line is remaining low after a previous commands response which causes the card to not work correctly.

Hi Wayne_
Yes, I´m using Hardware SPI routines. The code I posted above is not the code I´m writing now that I want to save the data in raw mode. As you well appointed, I´m saving the data as a 16 bit number together with a sequential number to ensure the storage is done correctly.

I tried to implement your pseudocode but it didn´t work, I had troubles with interruptions. I want to use interruptions to take the samples as accurately as possible. It does not mean your pseudocode is wrong, I think my implementation was not so good. Now I´m trying again but saving data after the array is full. Decreasing the sampling rate. For now decrease the sampling rate is ok for me, I need to have working this as soon as possible, so may be it will be not as I imagined but at least I want it saving data correctly. :-)

Thank you for the pseudo-code and thanks to ckielstra for his valuable comments.
