Arduino library for PCF8575 - 16 channel I2C IO expander. Description The library gives easy control over the 16 pins of the PCF8575 chips. Base address = 0x20 + 0..7 depending on address pins A0..A2. typeaddress-rangenotes PCF85750x20 to 0x27same range as PCF8574 !
The standard I2C library for the Arduino is theWire Library. While this library is sufficient most of the time when you want to communicate with devices, there are situations when it is not applicable: the I2C pins SDA/SCL are in use already for other purposes, ...
which abstracts the I2C bit-level and byte-level communication away from each specific device class, making it easy to keep the device code clean while providing a simple way to modify just one class to port the I2C communication code onto different platforms (Arduino, PIC, simple bit-banging...
The code is written primarily to support the Arduino/Wiring implementation, but it may be useful in other circumstances. There are multiple I2C/TWI implementations selectable in the I2Cdev.h header file if the default Arduino "Wire.h" is not available or preferable for any reason. There are e...

I2C mode it can have two different addresses, achieved by connecting the SDO pin either to Ground (for base address = 0x76) or to Vdd (for base address +1 = 0x77). In SPI mode it has the usual arrangement of 1 clock, 2 data (one for each direction) and a device select pin (...
Wire Library The Wire library allows you to communicate with I2C devices, often also called "2 wire" or "TWI" (Two Wire Interface). Download: Wire is included with Arduino Richard Gemmell has written an improved I2C library for Teensy 4.0. ...

Arduino I2C master library A better I2C master library, originally by Wayne Truchsess. Seehttp://dsscircuits.com/index.php/articles/66-arduino-i2c-master-library On most Arduino boards, SDA (data line) is on analog input pin 4, and SCL (clock line) is on analog input pin 5. On the ...
I2C multiplexingSometimes you need to control more devices than possible with the default address range the device provides. This is possible with an I2C multiplexer e.g. TCA9548 which creates up to eight channels (think of it as I2C subnets) which can use the complete address range of the ...
