EVM Bill of Materials

The two power-down bits of the TSC2007 can be set from this panel as well. A brief description of the mode selected is shown on the screen when setting these bits; see Table 3 (Command Byte Definitions) of the TSC2007 data sheet (SBAS405) for details on what these bits do.

6.4.4Datalogging

The software can record the data it takes from the TSC2007 to a tab-delimited file, suitable for importing into spreadsheets. To do this, first go into the File menu, and select Log Data to File..., which opens a file-select window and allows you to specify a file to which to write the data. At the same time, this enables the Datalogging menu.

When ready to begin recording data to a file, select Datalogging → Start Logging. Data is written to the file until Datalogging → Stop Logging is selected. When the screen is not touched, the AUX and TEMP values are written to the file, and the X, Y, Z1, and Z2 parameters are written to the file with values of 9999, to indicate that they are not updated. When the screen is touched, the X, Y, Z1, and Z2 parameters are written while the AUX and TEMP values are written to the file as 9999. Because the program constantly updates at a rate of about 400 readings per second, datalog files can quickly grow large; therefore, log only that data which is necessary.

The format of the data file has the first column as the time in milliseconds (which is just a timer in the program; it can arbitrarily start at any number), then X, Y, Z1, Z2, AUX, TEMP0, and TEMP1 columns. Every new reading is a new row in the file.

Table 7 and Table 8 contain a complete bill of materials for the modular TSC2007EVM evaluation board and the USB-MODEVM interface board, respectively (included only in the TSC2007EVM-PDK).
