TSC Starterkit (SK-TSC-1127-SB)

Description

The SK-TSC-1127-SB is a starter kit and evaluation system for the FMA1127 Touch Sensor Controller (TSC). It features a slider consisting of eight capacitive touch elements as well as four single buttons and six LEDs. The kit uses an SK-16FX-EUROSCOPE Starter Kit (to be ordered separately) with a 16FX MCU (MB96F348) as host platform, so that the user can easily develop and debug own TSC applications using the Softune Workbench and the EUROSCOPE debugging environment. Alternatively, the touch board can be connected to the EVALB1127 TSC Tuning Kit (to be ordered separately) or another host with I2C interface. The TSC touch board is connected using a 10-pole ribbon cable which holds the power supply lines, the I2C connection as well as reset- and interrupt lines.

Software

In this demo application, the raw touch data of the slider elements is read by the MCU, which then performs an interpolation algorithm to increase the absolute position resolution. The Buttons are directly read using the APIS mode I of the TSC. To enable easy parameter tuning for different applications, a command-line interface is provided, so that all parameters can easily be accessed and monitored using a PC Terminal program such as the Fujtisu StartkerKit Wizard (SK-Wizard).

As soon as the Slider or one of the four buttons is touched, the two 7-segment LED displays on the SK-16FX-100PMC will indicate either the slider position (from 0-99) or the number of the touched button (“b.1” – “b.4”).

Additionally, a standard, parallel LCD (20x4) can be connected to the ADA-16FX-TSC-LCD. When the LCD is present, in addition to the slider position and the pressed buttons, also the distribution of the touch strength among the slider elements is shown on the LCD as soon as the slider is touched.
