LPR2430ERA Hardware
The major hardware component of the LPR2430ERA is
the CC2430 IEEE 802.15.4 compatible transceiver with
integrated 8051 microcontroller. The LPR2430ERA op-
erates in the frequency band of 2405 to 2475 MHz at a
nominal output power of 63 mW.
The LPR2430ERA includes a low noise preamplifier in
the receiver path and a power amplifier in the transmit-
ter path, greatly increasing the operating range of the
CC2430. Two crystals are provided to operate the
CC2430, a 32 MHz crystal for normal operation and a
32.768 kHz crystal for precision sleep mode operation.
The LPR2430ERA provides a variety of application
hardware interfaces including a UART interface, three
11-bit ADC inputs, two PWM (DAC) outputs, and six
general purpose digital I/O ports.
LPR2430ERA Firmware
The main firmware components in the LPR2430ERA
include the 802.15.4 Media Access Control (MAC) layer
and the CNL V2.0 Networking Layer. CNL V2.0 sup-
ports up to 63 remotes. Network topologies include
point-to-point, point-to-multipoint and peer-to-peer. CNL
employs one-hop relay forwarding to mitigate network
transmission problems such as multipath fading. CNL
includes provisions for low-power sleep mode operation
with periodic wakeup and report. The CNL Application
Programming Interface (API) provides an easy-to-use,
flexible set of application commands and functions.
The API includes support for send/receive serial data,
read/write GPIO, read ADC inputs, write PWM outputs
and module configuration services. In addition, CNL
supports analog and digital I/O binding, which maps an
ADC measurement and the states of two digital inputs
on one LPR2430ERA to a PWM output and two digital
outputs on another LPR2430ERA. See the LPR2430
Series Integration Guide for complete details of the
CNL API.
