Interfacing real world devices to a microprocessor has become increasingly more difficult. It usually takes several discrete components to condition real world analog and digital before they can be ...

The most common method for interfacing multiple switches—multiplexing— allows for the connection of (N/2)2 switches with N microcontroller IO lines. The method described below, which has its roots in ...

Interfacing microprocessors to LEDs or LED displays via a 2-wire, I2C-compatible serial interface, the MAX6958/6959 common-cathode LED display drivers are said to be the first such devices to offer ...

The MAX7221 is a compact, serial input/output common-cathode display driver that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 ...
