First example: read test

See C++ FX22MB_REG0_START_TX example.

Second example: write test

See C++ FX22MB_REG0_START_RX example.

Third example: select module, read firmware version, read VID/PID

This example program implements a simple console that

  1. creates an instance (TE_USB_FX2_USBDevice) initialized to null of the class CyUSBDevice
  2. reads and displays the number of Trenz Electronic modules (TE_USB_FX2_ScanCards())
  3. selects the first (0) Trenz Electronic module: modifies the instance of the class CyUSBDevice, making this instance different from null and properly initialized with the data of the selected Trenz Electronic module. If no module is attached, the instance remains initialized to null.
  4. reads and displays VID and PID of the selected module
  5. reads the firmware version of the selected module
  6. selects the second (1) Trenz Electronic module: modifies the instance of class CyUSBDevice to represent the new selected Trenz Electronic module. If the selected module is not attached, the instance is reinitialized to null and the reference to the previous module (0) is lost.
  7. reads the FPGA firmware version of the second (1) module
