EVALB1127 (EVALB1127-Support)

Description

EVALB1127 is a Tuning Kit for FMA1127 series Touch sensor controller devices. This tuning kit helps the developer to tune the target touch board with various parameters that determine the performance. The tuning system is connected between the PC and the target touch board. It allows the developer to view all necessary parameters for tuning and transfers the desired values of parameters to the attached target touch board.

The tuning kit for FMA1127 consists of one USB interface board and several touch boards with different pad patterns. User can send commands to the MCU in the USB interface board from PC and eventually set registers of FMA1127 on the touch board. Touch data from the touch board will be transferred to PC through the USB interface board for displaying. The MCU in USB interface board will control FMA1127 in the touch board via I2C interface by reading/writing data accessing internal registers of the FMA1127.

User can decide and set various parameters such as sensitivity values for each individual input channel, AIC™ (Automatic Impedance Calibration) interval, threshold value above which the sensor will detect the touch, APIS™ (Adjacent Pattern Interference Suppression) modes etc.

Features

The kit includes the following features:

• 3 Touch Boards with different pad pattern design
• Touch boards mounted with FMA1127DC
• Four I2C slave selectable interfaces to connect touch boards with Host MCU on kit
• 10pin I/F connector to connect target Touch boards for Tuning
• On-board 3V/5V voltage regulator, 'Power'-LED
• Battery-supply (external power supply possible) or 5V USB supply is possible.
• PC installation program for user GUI
• All FMA1127 registers are accessible for read and write though PC GUI
• Kit includes a CD ROM having all documents and software:
  Data sheet, Tuning Guide, PC installation program
