Kit Overview

The Freescale's TWR-SENSOR-PAKTWR-SENSOR-PAK is a module in the Tower System that features swappable sensor modules, or plug-ins. These swappable plug-ins allow you to rapidly evaluate and compare an expanding portfolio of sensors. Using real-time sensor data and interaction with your environment, it's easy to sense your world with the TWR-SENSOR-PAK.

The TWR-SENSOR-PAKTWR-SENSOR-PAK includes the following Tower Plug-ins (TWRPI’s) that feature Freescale Sensors:

TWRPI-MMA7660, featuring the MMA7660FC Digital Accelerometer
TWRPI-MPL115A, featuring the MPL115A Digital Miniature Barometer
TWRPI-MPR121, featuring the MPR121 Proximity Capacitive Touch sensor

The TWR-SENSOR-PAKTWR-SENSOR-PAK also features the TWRPI-TSS plug-in, which enables the use of the Freescale Touch Sensing Software Suite (TSS).

The TWR-SENSOR is the base Tower module. The TWR-SENSOR module utilizes the MC9S08QE96 MCU to interface directly to the sensors and to communicate with the Freescale Tower System as either a slave MCU of a master MCU, with limited capabilities. The TWR-SENSOR also utilizes the MC9S08JM60 MCU. This MCU is used to provided serial communication over USB and provide Open Source BDM functionality to the MC9S08QE.

The TWR-SENSOR module features two general purpose sockets that can be interchangeable populated with the included accelerometer and barometer plug-ins and will be utilized by the majority of future TWRPI’s. This general purpose plug-in socket can utilize I²C, SPI, analog signals, and GPIO’s to interface the plug-in’s featured device with the MC9S08QE. Additionally there are two sockets dedicated to capacitive touch capabilities. One socket is utilized by the actual touch sensing device; the second socket is used to provide access to the capacitive electrodes.

The TWR-SENSOR module includes the following on-board sensors:

Freescale MPR03X Capacitive Touch Controller (with dedicated touch pads)
Sensirion SHT21SHT21 Digital Humidity and Temperature Sensor
Intersil ISL29011 Ambient Light Sensor with Proximity Detection
Vishay TSOP36236TSOP36236 36kHz IR Receiver Module

All sensors (on-board and plug-ins) are designed to interface directly with the on-board MC9S08QE. The TWR-SENSOR MC9S08QE has full access to all sensors, including I2C, SPI, analog, and GPIOs used on the TWRPI sockets. Sensors that utilize I2C and/or analog signals (general purpose sockets only) can also interface directly to an additional Tower System MCU via the Tower System Elevator.

Key Applications: Portable Electronics and space constrained applications, battery and other low-power applications
