Tower System

Expand the capabilities of the Freescale Tower System with the easy-to-use, plug-in analog module (TWR-ADCDAC-LTC) developed in conjunction with Linear Technology. Quickly access the capabilities of the analog module via a simple configuration from the serial port (SPI or I2C), with read and write capabilities to the analog-to-digital converter (ADC) or the digital-to-analog converter (DAC). Add analog to a broad array of applications such as sensing, battery charging, medical, and more. This peripheral module is designed to be combined and used with other MCU and peripheral modules in the Tower System.
