HS NMEA GPS C Source Library
$0 - Hillstone Software
HS GPS is a software library (with full C source code) which provides access to a NMEA-183 compliant GPS receiver via a serial communications port, decoding NMEA sentences: $GPGGA, $GPGSA, $GPGSV, $GPGLL, $GPRMC and $GPVTG. Decoded parameters include: time, date, position, altitude, speed, course and heading, according to standard - NMEA-183 (National Marine Electronics Association, Interface Standard 0183.
* HOW IT WORKS: HS GPS library continuously reads asynchronous data stream from a serial port and analyses the information to recognize and decode NMEA-183 Protocol sentences. After each message is received it is checked for integrity by comparing the received and the calculated checksum. The NMEA sentence fields are then converted from ASCII values into C structure variables and passed up to user application code.
* Applications
- Navigation
- Security
- Telematics
- Fleet Tracking
- Asset Tracking
- Any customer applications requiring access to a NMEA-183 compliant GPS receiver
* Features
- Interfaces a GPS receiver over COM ports COM1 - COM8
- Decodes most commonly used NMEA sentences from a GPS receiver:
- GGA - Global Positioning System Fix Data
- GLL - Geographic Position
- GSA - DOP and Active Satellites
- GSV - Satellites in View
- RMC - Recommended Minimum Specific GNSS Data
- VTG - Course over Ground and Ground Speed

HS XMODEM C Source Library
$0 - Hillstone Software
HS XMODEM is a software library in C (supplied with full source code) that provides a programmer with the off-the-shelf support for XMODEM protocol data transfer capability. Support for both sender and receiver are provided. Other features include 1024 block size vs 128, CRC vs checksum, configurable timers and retries
* HOW IT WORKS:
When user application initlialises HsXmodem library, it provides interface callbacks for the services used by Xmodem protocol module: timer management, serial transmission and reception, memory management, event callbacks. This architecture makes it easy to port Xmodem protocol module to any environment
Xmodem module handles all protocol information flow, error recovery, acknowledgements, timeouts and so on. When it is appropriate to send next block of data Hs Xmodem will get next memory block from user application. Similarly, when data has been received Hs Xmodem module will get the next block of memory from user application to store data into
As a backup or an alternative to TFTP, Xmodem is often used in embedded devices and appliances for the purpose of software or configuration upgrade or retrieval.
* FEATURES:
- Xmodem Sender and Receiver
- 128 and 1024 block size
- Checksum and CRC option
- Configurable timers
- Configurable number of retries
* HOW TO BUY HS XMODEM LIBRARY:
You can purchase the library online using credit card payment at:
