I think I did not make it clear in my first post the reason why I transmit the data with 4 separate polling transmit calls. It's because after writing to channel A of the DACs the CS pin must go high to latch in the data. Then I can write to channel B and so on. GPIO 15 is just a debug pin, the CS i...

I'm using the SPI to communicate with 5 quad channel DACs connected as shown in the diagram. On a timer interrupt I write to all the DAC channels with successive spi_device_polling_transmits. This is required to latch the data into the DAC registers with the CS line. What I need to to is reduce the ...
