Quick Start Guide TWR-SHIELD Shield Adapter Module for the Tower System TOWER SYSTEM Quick Start Guide Get to Know the TWR-SHIELD Primary Elevator Shield Headers Power Regulation (5 V and 3.3 V) Advanced Configuration Options "Arduino Shield" (not included) Shield Headers Secondary Elevator TWR-SHIELD Freescale Tower System The TWR-SHIELD module is part of the Freescale Tower System, a modular development platform that enables rapid prototyping and tool re-use through reconfigurable hardware. This module allows commercially available Arduino Shields to be incorporated into the Tower System. Take your design to the next level and begin prototyping with your Tower System today. 2 TOWER SYSTEM TWR-SHIELD Features *Arduino Shield (R3 Compatible) headers *On-board power regulation (3.3 V and 5 V) Recommended input voltage: 7-12 V Input Voltage Range Limits: 6-20 V *Default signal configuration for ease of integration with the Freescale Tower System *Flexible advanced signal configuration options and signal access 3 Quick Start Guide Step-by-Step Instructions 1 Configure Jumpers The TWR-SHIELD comes preconfigured to accommodate basic interfacing with a Freescale Tower System controller module. If modifications are required, the small trace between the default connections can be cut and wire can be soldered in place to make the modified signal routing. Additionally a 3-pin header can be soldered in place to allow for increased flexibility. Refer to the TWR-SHIELD User Manual for details. 2 Attach Shield With the correct signals routing identified, connect your R3 Compatible Shield to the TWR-SHIELD. Shields headers have a unique spacing that will aid in determining the correct orientation. 4 3 Assemble and Power Your Tower System Assemble your Tower System, including a Tower System controller module, the TWR-SHIELD peripheral module and the shield(s) of your choice. Refer to the assembly instructions provided with the TWR-ELEV module for correct orientation and assembly of the boards. The Tower System can be powered using one of the standard powering methods or using the Vin pin of the shield header. The Vin pin will accept a 6-20 V input voltage and provide the necessary 5 V and 3.3 V to the entire Tower System assembly. 4 Refer to Additional Materials Many existing MQXTM software example projects can be adapted to utilize the basic I/O interfaces featured on most peripheral shield modules (e.g., UART, I2C, GPIO, ADC, etc.). Reference the TWRSHIELD user manual and the latest MQX release notes for details. TOWER SYSTEM TWR-SHIELD Jumper Options The following is a list of configuration options.
