 GPIO Timing accuracy Hi All
If I go through all the trouble of using GPIO and interfacing it to a Solid State Relay,
what would be the output pin timing accuracy.
For example, I need to drive a pneumatic solenoid that has to be ON for 300 mSec.(operator adjustable)
Using usb I am getting 3 or 4 mSec variation, with an occasional 11 mSec variation.
The 11 mSec variation is the problem.

Re: GPIO Timing accuracy Using fitlet GPIO cable you interface the GPIO HW directly with very simple and not memory-consuming drivers, what keeps the time delays to really minimum values, and the operation is real time.

Re: GPIO Timing accuracy Hi All
Thank you for the reply mbirger, one final point:
Where do I find what the maximum load in milliamps is for those outputs ?

Re: GPIO Timing accuracy This may answer your question - it is a bit "buried" in the wiki. http://www.fit-pc.com/wiki/index.php/FA ... pabilities
