This package contains a simple test of tests for various elements of the SmartBoard hardware, which is a simple baseboard designed for easy embedding. It is able to run both a semi-automatic test suite as well as allow interactive testing.
Dependencies: EthernetNetIf NTPClient_NetServices mbed
This program is most of what you need to test your SmartBoard baseboard hardware. It provides a means to test the following:
- Two channels of CAN (with a loopback cable)
- RS-232 Ports
- Analog inputs
- PWM outputs
- Ethernet port
- Real time clock
- micro SD
- USB Host port
