MBed and a PCF8574

The PCF8574 is an 8 bits I/O port expander that uses the I2C protocol. Using this IC, you can use only the SDA and SCL pins of your Arduino board to control up to 8 digital I/O ports.

A0,A1,A2 are address pins P0,P1,P2,P3,P4,P5,P6,P7 are digital I/O ports SDA,SCL are the I2C pins

mbed LPC1768 and LCD example

In this example we connect an LCD to our mbed LPC1768 and display some text on it, we use a library to do most of the hard work here so our developmentĀ is made easy by the TEXT LCD library.

The schematic shows how to connect up the 16×2 LCD to the mbed LPC1768
