Free gps pda program

Another nice thing about MentStat is its small size; it uses only 8 KB of memory. In some cases, it provides etiologies or causes of certain entries, such as lactic acidosis. For example, some of the things I have found useful to store in my Memo Pad include:.

The following articles from the Family Practice Management archives can be accessed free online.

Having It All, a Littl Free software uses the General Public License GPL to protect the availability of code and prevents that code will not be included in proprietary binary-only system.

Benefits coming from the use of free software are several. The main evidence is that institutions and individuals that do not possess financial resources for commercial software could go ahead with their research activity without worrying about licenses fees, concentrating financial resources in acquiring scientific skill.

The core benefit stands in that science should be based in sharing knowledge and not in hiding it. So a code could be developed by all the people interested in it, with different pro- gramming skills and different point of views.

Another benefit is that academic codes, e. In this way even complex projects could grow in the years. That seemed a good deal since Motorola Dragonball devices could cost less than a half than Intel StrongArm based platforms.

To maintain usability of software with different GPS unit the latter format has been used as it represents a standard in navigational systems communications. The NMEA protocol was first released in March of and defines the electric signals requirements, data trans- mission protocol, timing and specific sentence formats for a EIA serial data bus. The electrical interface standard allows a single talker and several listeners on a line.

Data fields are separated by commas and the absence of data will leave an empty field between two commas. In table 1 a typical NMEA version 2 sentence is reported. The NMEA protocol provides also query sentences to obtain specific information from a device GPS receiver or other navigational systems. WABA together with Waba Extras extension written by Rob Nielsen 3 allows to insert either simple data field to be filled, or pup-up lists with selectable entries, as the case of feature entry in figure 2.

Once the information has been entered, user can choose to read the position from gps receiver tapping on the GPS button. The position could be also entered directly by hand. If the site data is good, tapping on the save button saves the data and a new empty page to be filled is presented.

Previously acquired data can be browsed with arrows button. Dataset can be transferred with pilot-xfer program from the pilot-link suite that has to be previously installed in your system. The conversion is made with pdb2gasites. This will facilitate geologic field work and speed up data storage in electronic format. PGS runs on a wide range of PDAs and also on cheaper low-end ones, so that also private experimenters or students could deal with it.

The choose of Free Software opens the code to the public so that eventually present bugs not recognised at the moment can be fixed, and the software usability improved. Feedback is welcome and will be really precious to improve and extend the functionalities of the software.
