Overview
========
The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The Hello
World demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is to
show how to use the UART, and to provide a simple project for debugging and further development.
Toolchain supported
===================
- Keil MDK 5.24a
- IAR embedded Workbench 8.22.2
- GCC ARM Embedded 7-2017-q4-major
- MCUXpresso10.2.0
Hardware requirements
=====================
- Mini/micro USB cable
- MAPS-KS22F256 board & MAPS-DOCK board
- Personal Computer
Board settings
==============
The hello_world demo 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
Prepare the Demo
================
1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
2. Open a serial terminal with the following 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.
Running the demo
================
The log below shows the output of the hello world demo in the terminal window:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
