Overview
========
The LPI2C Example project is a demonstration program that uses the KSDK software to manipulate the Low Power Inter-
Integrated Circuit.
The example uses two instances of LPI2C, one in configured as master and the other one as slave.
The LPI2C master sends data to LPI2C slave. The slave will check the data it receives and shows the log.
Toolchain supported
===================
- Keil MDK 5.24a
- IAR embedded Workbench 8.22.2
- GCC ARM Embedded 7-2017-q4-major
- MCUXpresso10.2.0
Hardware requirements
=====================
- J-Link ARM
- Mini USB cable
- MAPS-KS22F256 board & MAPS-DOCK board
- Personal Computer
Board settings
==============
The freertos_lpi2c example is configured to use UART1 with PTE0 and PTE1 pins. To make JLink serial
device work, the jumpers on MAPS-DOCK board should be set as following:
- JP7 on MAPS-Dock: UART0 related jumpers connected
To make this demo work, connections on MAPS-KS22F256 board need to be setup as follows:
- PTB0(Pin53) --> PTC10(Pin82);
- PTB1(Pin54) --> PTC11(Pin83);
- JP13 Connected
- JP14 Connected
Prepare the Demo
================
1. Connect a mini USB cable between the PC host and the USB port (CN14) on MAPS-DOCK board.
2. Open a serial terminal on PC for JLink serial device with these settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
3. Download the program to the target board.
4. Either press the reset button on your board or launch the debugger in your IDE to begin running
the demo. For detailed instructions, see Getting Started with Software Development Kit for
KS22F25612 (document SDKKS22F256GSUG).
