Microchip PIC32 M2M GSM/GPRS/GPS解决方案

Microchip’s Machine-to-Machine (M2M) PICtail Daughter Board (part # AC320011) based upon u-blox GPS and GSM/GPRS modules makes it easy to create low-cost M2M applications with location-awareness capabilities.

The M2M PICtail Plus Daughter Board contains many features, including GSM, GPRS, and GPS.

M2M PICtail Plus子板主要特性:

Global System for Mobile Communication (GSM)

GSM is a popular world-wide standard for mobile telephone systems. GSM includes technologies in both signaling and speech channels, which are digital; therefore, GSM is considered a Second Generation (i.e., 2G) mobile phone system. This facilitates the wide-spread implementation of data communication applications into the system. GSM also implements a Short Message Service (SMS), called text messaging.

General Packet Radio Service (GPRS)

GPRS is a service on 2G and 3G cellular communication systems (GSM). GPRS provides data rates of 56-114 kbps, which provides users with the capability to connect to the Internet.

Global Positioning System (GPS)

GPS is a space-based navigation system that provides reliable location and time information in all weather conditions and at all times, and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites.

It is freely accessible by anyone with a GPS receiver.

The Microchip M2M PICtail Plus Daughter Board (referred to as the M2M Board) developed by u-blox AG, was designed to connect directly to the PICtail interface of the Multimedia Expansion Board (MEB), but can also be used with any PIC32 microcontroller.

This application note describes a reference design that enables the implementation of GSM/GPRS/GPS connectivity using a PIC32 microcontroller (MCU), the M2M Board, and the MEB.

M2M PICtail Plus子板主要功能:

The main functionality of the M2M Board is accomplished using two communications modules from u-blox A, which is a company that specializes in GSM/ GPS ICs.

The M2M Board was designed to connect to Microchip’s MEB. The MEB uses Microchip’s PIC32 starter kit collection as the primary controller source.

This suite makes it easy to start and implement embedded controller projects due to its:

Built-in debugger

USB power source

On-board header for easy attachment to PCBs

PIC32 device with high-speed performance and no peripheral loss

The M2M Board is built around two controller modules, the LEON-G200 and the NEO-6Q, which are available from u-blox AG.

The LEON-G200 is a Quad Band GSM/GPRS data and voice module. Communications to the module are through AT commands. The UART module on the PIC32 device handles the AT commands. The LEON-G200 handles the GPS communications to the NEO-6Q module. The module also contains 1 MB of non-volatile memory that can be used for storing local or Internet files.

The NEO-6Q GPS module uses the u-blox sixpositioning engine for its GPS positions support. In this hardware setup, it acts as a slave to the LEONG200, but can be a stand-alone module with its own set of AT commands.
