Touch Sensing Software Evaluation Board (TSSEVB) User Guide
Hardware guide for the TSSEVB featuring the MC9S08LG32 MCU, designed for evaluating NXP's Touch Sensing Software (TSS) library for capacitive touch applications.
Overview
This user guide provides a comprehensive hardware overview of the Touch Sensing Software Evaluation Board (TSSEVB). Designed around the NXP MC9S08LG32 microcontroller and the Touch Sensing Software (TSS) library, the board enables the evaluation of capacitive sensing technologies. The document includes detailed schematics, a complete bill of materials (BOM), and silk screen layouts. Key features described include the dual-MCU architecture (MC9S08LG32 for touch and MC9S08JM60 for communication), onboard touch electrodes, LCD, buzzer, and multiple interface options including USB, I2C, and SCI. It also covers power supply configurations and jumper settings for development.
Use Cases
- Evaluating NXP Touch Sensing Software (TSS) library
- Developing capacitive touch user interfaces
- Prototyping with MC9S08LG32 microcontrollers
- Testing I2C and USB communication for touch applications
