Re: Crosstalk and sample frequency issues on a pressure sensor matrix
One resistor to ground before the multiplexer, the series diode should not be needed. The walue of this resistor should be adjusted to be approximately equal to the velostat layer resistance for one crossing when half depressed. If you dont have a pull down resistor the the sense line becomes "...
