![]() In this mode, only a current source to V CC is active. Each quasi-bidirectional I/O can be used as an input or output without the use of a data-direction control signal. Here I explain the manage of multiple rotary encoder. This IC can control (until 8) digital devices like button or led with 2 only pins. ![]() The device features a 16-bit quasi-bidirectional input/output (I/O) port (P07–P00, P17–P10), including latched outputs with high-current drive capability for directly driving LEDs. Library to use i2c pcf8574 IC with arduino, esp8266 and esp32. ![]() Open the Proteus software and search for Arduino. The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I 2C interface. Extract these two files and paste them in the libraries folder of your Proteus software. ![]()
