Program Description
Kit Operation
As configured from the factory, the board is ready to use with the TSC2006EVM. However, if external SPI
control is desired, the signals may be applied to J15, as long as the SW2 is set to OFF position so that
USB SPI control is disabled. To view all the functions and configuration options available on this board,
see the USB-MODEVM Interface Board schematic in Section 7.2.

After the TSC2006EVM-PDK software installation (described in Section 6.2), evaluation and development
with the TSC2006 can begin.
with the TSC2006 can begin.
Running the TSC2006EVM-PDK software on your PC displays the interface GUI as shown in
. On
the top-left side of the GUI, a lit green LED indicates the digital serial interface type, which should be SPI
for the TSC2006EVM-PDK. The next box shows the location and reversion of the firmware.
for the TSC2006EVM-PDK. The next box shows the location and reversion of the firmware.
The two LEDs on the top right corner of the GUI can be used to reset TSC2006 by software and to stop
the TSC2006's ADC operation. Note that the two LEDs reflect the corresponding bits inside the CB1.
When the SW Reset LED is lit (in blue), the bit 1 of CB1 is set to logic 1 and TSC2006 is in the software
reset mode; when the LED is OFF (in black), the bit 1 is set to logic 0 and TSC2006 is not reset and is in
normal mode. When the Stop ADC LED is lit (in red), the bit 0 of the CB1 is set to logic 1 and TSC2006's
ADC is stopped. When this LED is OFF (in black), the bit 0 is logic 0 and TSC2006 is running in normal
operating mode.

On the top-right side of the GUI, two boxes labeled CB0 and CB1 display the current/default settings of
the TSC2006 control byte mode 0 (CB0) and mode 1 (CB1), respectively. See the TSC2006 data sheet on
the control byte and its two modes.
the TSC2006 control byte mode 0 (CB0) and mode 1 (CB1), respectively. See the TSC2006 data sheet on
the control byte and its two modes.
The data in CB0 is written to TSC2006 while writing to a control register, and CB0 is the common byte.
The data in CB1 is written to TSC2006 while one of the following occurs:
The data in CB1 is written to TSC2006 while one of the following occurs:
•
Bit 0 (STS or Stop ADC) is set by clicking on the LED in left/top corner.
•
Bit 1 (SWREST or SW Reset) is set by clicking on the SW Reset LED.
•
Bit 2 (RM or Resolution) is set at the Human Interface tab.
•
Bits 3 through 6 (Converter Function Select) can be set at this tab beneath the CFR1 section.
The majority evaluation can be implemented using three tabs on the TSC2006EVM GUI: Human Interface,
Configuration, and Command Line Interface. Clicking on a tab accesses the functions corresponding to
the tab. The following discussion details the three tabs.
