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.
