Has anybody managed to use Embrio for data logging to an SD card? If so I'd appreciate a look at the custom node. Thanks.

I used this as a base and made the custom node that you can copy and paste below. It logs 2 input activations and has outputs that are turned on when the hardware is found or there is an error. You can put the logging on an agent and either change the refresh rate to set how often data is logged, or add a trigger input and copy the EveryUpdate code to the trigger event, and use a repeating timer to trigger the data logging.
