lpi2c_interrupt#
Overview#
The lpi2c_functional_interrupt example shows how to use lpi2c functional driver to build a interrupt based application:
In this example , one lpi2c instance used as lpi2c master and another lpi2c instance used as lpi2c slave .
lpi2c master send data using interrupt to lpi2c slave in interrupt .
lpi2c master read data using interrupt from lpi2c slave in interrupt .
The example assumes that the connection is OK between master and slave, so there’s NO error handling code.

FRDM-MCXA577
Hardware requirements
Type-C USB cable
FRDM-MCXA577 board
Personal Computer
Board settings
MASTER(LPI2C0) connect to SLAVE(LPI2C1)
Pin Name Board Location Pin Name Board Location
SCL J2 pin 20 SCL J5 pin 5
SDA J2 pin 18 SDA J5 pin 6
Other jumpers keep default configuration.
Prepare the Demo
Connect a USB Type-C cable between the host PC and the MCU-Link USB port on the target board.
Open a serial terminal on PC for the serial device with these settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
The following message shows in the terminal if the example runs successfully.
