Other Parts Discussed in Thread: DAC81416, C2000WARE
Tool/software: Code Composer Studio
On my prototype board F28388 and TI’s DAC module 81416 are installed.
F28388 SPIA is wired to DAC81416.
Now I would like to ask how to send effective data from F28388 to DAC81416.
I am referring DACx1416 document JAJSFP9A, and I would like to send data as “10.5.1.1 Streaming Mode Operation”.
The section of the document says SPI data structure should be 8bit + 16bit + 16bit + ..... The first 8 bit of data is W/R identification and register address.
Then following 16-bit data are the one to be written into register if write mode.
On the other hand, I also referring C2000Ware’s f2838x example projest, especially, spi_ex1_loopback.c.
This example seems to send “16 bit” data stream(16bit + 16bit + 16bit + ....). In other word, 16bit seems to be an unit as sending data.
How should I send first 8bit for DAC81416?
