Hi all, i searched but couldn't find anything similar enough.
i'm looking to interface a capacitance touch panel (TTP224) with a digital potentiometer (MCP4011) with a 555 to pulse the output.
I need to pulse the +V or the 0V but not together, how can i make the MCP4011 digi-pot see only high or low pulses from a 555 timer? will a simple blocking diode be sufficient? this is just at the planning stage so far. Thanks all. (i'm a bit of a newbie)
