David Smart / Mbed 2 deprecated A_SmartBoard_HWTester

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
