Changes

On starting the GoGo activity the Console-Tab is displayed as shown below. In the top of the central region is the name and version of the activity. Please quote the version number if you encounter any problems (on SugarLabs Bugs site [4]). In the center is the image of the GoGo-Board itself, which will be larger is the next version. Below that is the current status "GoGo Connected"/"GoGo Disconnected" followed by "Connect"/"Disconnect" buttons. Also note the status-bar at the bottom of the screen which displays (sometimes transient) messages.

Logo procedures can include commands to capture data and store it on-board until uploaded to the XO. This can be done on the "Data Upload" tab (shown below) by clicking on the "Start" button (top left). The adjacent progress-bar and upload-count will update as data is uploaded. The data will be displayed in the "Recorded Data" section after the upload completes. Data can be displayed in Table or Graph format. In Table format the data can be formatted across a number of columns, which is required when data from more than one sensor/ source is interleaved. A sensor "type" can be selected to display the name & units and to apply calibration to for each column (see next section for how this information is created). Sensor Names & Units are used to display column headers. Name and Unit can be on the same line ("Name (Units)") or split on their own line (a two-line header). Data can be saved in Comma-Separated-Variables (CSV) format along with one/two headers (if selected).

===Sensor-Lab Tab: Calibration Data===

===Sensor-Lab Tab: Calibration Data===

Sensor values, even for switches, fall in the range 0..1023. The Sensor-Lab is where particular sensor "types" can be created to calibrate these values, give more meaningful names and specify the units used (eg, Resistance, KOhms). Calibration data is defined by specifying a number of calibration "points" between which the application will interpolate to convert the raw sensor values. In this way a library can be created of commonly encountered sensor types and their calibration data can be assigned when monitoring sensors in the Console tab and when importing captured data in the "Data Upload" tab. In the image below you can see the list of sensors, the calibration points for the selected sensor and a (slightly rough) idea of the shape of the calibration curve in the graph. For easier creation and editing of calibration data the information for each sensor can be exported and imported in both Comma-Separated-Variables (CSV) format or custom "Sensor" format. Like-wise sensor information can imported in either of these formats.

...yep, user "olpc" is a member of "dialout". So in the above example all is well. If your results differ from these then please post a bug at SugarLabs Bug website [4]. Note that some older XO/OS's use different device files and/or groups and it may need root access to fix any problem.
