1.2 Interface module features and architecture

This section describes the main features of the interface module and its architecture.

1.2.1 Features

The main features of the interface module are as follows:

• two Bosch CC770 Controller Area Network (CAN) controllers

• two 8-channel 12-bit Analog to Digital Converters (ADC) with 200ksamples/s

sampling rate and 0-5V buffered inputs

• two 12-bit Digital to Analog Converter (DAC) channels with 0-5V outputs

• two L298 stepper motor drivers configured for bipolar motors

• two stepper motor control outputs for use with off-board drivers

• two 3A MOSFETs configured as switches for the Pulse Width Modulated (PWM)

outputs

• RS232 serial transceiver

• two 32-bit General Purpose Input Output (GPIO) connectors

• JTAG (Multi-ICE) pass-through connector

• logic analyzer connector connected to the GPIO bus.
