Using DIOx line on NI-8452 as SPI_DATA (SPI_MOSI)

[RF1LP]

Hi,

Newbie to labview.  Would like to know if one of DIO lines on the NI-8452 can be configured as SPI_DATA  (SPI_MOSI).   Synchronizing it with the SPI_CLK.

I’m using SPI_CLK as the RCLK for 74hc595.   DIO1 as SER data input to 74hc595.  DIO2 as RCLK  for 74hc595.

Thanks.

Hey kvn,

Unfortunately, the DIO on the 8452 are all software-timed, so there isn't a way to tie their output to a hardware clock like SPI_CLK. They are really intended to be used as basic DIO lines for evaluating external conditions that may need to influence the execution of your application, rather than as hardware-timed input or output.

If you would like to read all of the capabilities for yourself, check out the NI-845x Hardware and Software Manual.

I hope this helps.
