nidaq card not outputting correct values when called multiple times with different data

[leoscholl]

Examples:

Data is on channels 17-24 Clock on channel 25

The clock signal is being overwritten by the data pulse

[leoscholl]

the temporary solution to this problem is to only send one command to the nidaq at a time. to do this, the clock is now also a single 3 ms pulse for each cycle rather than a single low-high or high-low transition on each cycle.

the long term solution is to buy another nidaq card to use for anything we need to be independently controlled, since it seems this is just a limitation of the device and/or driver.
