It would be useful to have a hardware trigger pin.
It would also be useful to have an output pin giving a pulse for every sample of the 16 channels that Saleae makes.
In that case measurements can be synchronized and multiplexed easily.
It would also be useful with an input pin, making Saleae take a 16 channel sample for each incoming pulse.
This would require 3 new pins, or one single pin that can be programmed for 3 different tasks.
This idea would be extremely useful, the way I see it. This would also help if you want to use more than one Saleae unit,
to capture 32 channels or 64 channels, I guess.
