README
PCx857x/PCF8574/PCF8575/PCA8574/PCA8575 - NXP/TI GPIO expansion
The PCX857X device family provides 8/16-bit, general purpose parallel I/O expansion for I2C SPI applications. These chips provide simple I/O expansion with reduced bus traffic as they don't take command bytes.
Documentation
PCX857X devices contain different markings to distinguish features like packaging, bus speed support, and address space. Please review specific datasheet for more information.
Usage
// 0x20 is the device address in this example.
var connectionSettings = new I2cConnectionSettings(1, 0x20);
var i2cDevice = I2cDevice.Create(connectionSettings);
var pcf8574 = new Pcf8574(i2cDevice);
Binding Notes
This binding includes an Pcx857x abstract base class and derived abstract classes for both 8-bit (Pcx8574) and 16-bit (Pcx8575) variants.
