Rtc Uart0; Xbee/Bluetooth/Wifi Wireless Communication - NEX ROBOTICS LPC2148 Pro Manual

Description: This application code drives unipolar stepper motor using ULN2003 driver on
the LPC2148 development board

4.12 RTC UART0

Hardware Setup: Connect a DB9 cable between PC and UART0. Setup the terminal
software with following settings:
Load the RTC_UART0.hex file from LPC2148>codes>RTC UART0 folder using flash
magic on the microcontroller flash memory.
Description: This application code demonstrates RTC peripheral on LPC2148. It transmits
current time in 24h format on UART0. Enable terminal to receive data in string format. By
pressing reset switch, the current time of RTC can be displayed on receive window of
terminal software.

4.13 XBEE/BLUETOOTH/WIFI WIRELESS COMMUNICATION

Hardware Setup: Refer jumper settings for using Xbee from section 3.8. Connect Xbee
USB adapter module to PC and install drivers. To install drivers refer Xbee USB adapter
module documentation available in the CD. Setup the terminal software with following
settings:
Enable terminal to receive data in string format.
Load the XBEE_WIRELESS_COMM.hex file from LPC2148 > codes > XBEE WIRELESS
COMM folder using flash magic on the microcontroller flash memory.
Description: This application code uses Xbee wireless module for communication over
UART1 peripheral on LPC2148. The jumpers settings are required to be changed in order to
select Xbee for UART1 on LPC2148 development board(see section 3.8). We will also
require a Xbee USB adapter module for receiving and transmitting data on the PC side.
Enable terminal to receive data in string format. After loading the hex file, press reset switch.
on microcontroller board, The microcontroller board will send the below message, which can
be observed on the receive window of terminal software on PC, where the Xbee USB module
is connected,
