The ENVLogger ● GPS & Temp,humidity & CO2 sensor !!
This was made. ● Skytraq S1315F GPS Logger ● It used it to experiment on goGPS.
Why is the GPS logger made? I am participating in OpenStreetMap. http://www.osm.org/ In OpenStreetMap, I want the GPS log that accuracy is as good as possible. Therefore, it thinks whether to obtain the position where accuracy by postprocessing is good by preserving raw data (raw data) of GPS. The other... GPS logger on the market ties and it doesn't tie an external antenna. It wants to obtain some accuracy even when it is not possible to measure it with GPS like the tunnel and to obtain the position that is. The capacity of GPS logger on the market in which the log can be done is small. Special software is necessary for taking out the log. It is general and wants the log data. It is freedom in above all. :-)
It actually used it. Make: Ogaki Meeting(2010-9-25)
Result The distance from Sakai to Ogaki is a round trip and about 400Km. Roughly 340Km was good at the log.
DIY GPS Logger (1.5G) The base substrate is changed to ☆board Orange.
Specification ● Main processor - mbed NXP LPC1768 ● Technical reference This mbed Microcontroller is based on a Cortex-M3 Core running at 96MHz, with 512KB FLASH, 64KB RAM and a load of interfaces including Ethernet, USB Device, CAN, SPI, I2C and other I/O.
Why is mbed used? Because it is easy. When it is usual development. 1) The development setting is installed. 2) ROM burnt wearing software is installed. 3) The debugging of the boot loader is serious. JTAG comes to want it.
What is different as for mbed? 1) The boot loader has already been made. 2) Writing in ROM is "Drag & drop" and OK!!. 3) The installation of the compiler is unnecessary. Because all are Web bases.
Thing that has been understood ● When it is a motorcycle, the acceleration and the gyro are difficult. It shakes, and the noise is large. ● The motorcycle can use a digital compass. ● It seems to be able to do the “simple earthquake sensor” by applying the acceleration sensor. ● Mbed is convenient.
