| 31 | Running the Demo |
| 32 | ---------------- |
| 33 | |
| 34 | 1. Download the selected example, or export the example to save the .atzip file. |
| 35 | 2. Import .atzip file into Atmel Studio 7, File->Import->Atmel Start Project. |
| 36 | 3. Build and flash into supported evaluation board. |
| 37 | 4. Connect PC host and TARGET USB plug with a USB cable. |
| 38 | 5. Press the RESET button. |
| 39 | 6. The serial port is detected by host PC. On Linux the driver will be installed |
| 40 | automatically. On Windows The INF and CAT file required can be extracted from |
| 41 | .atzip or found in generated Atmel Studio 7 project folder, relatively at |
| 42 | ./usb/class/cdc/device. |
| 43 | 7. Open the detected/enumerated serial port using a serial port monitor |
| 44 | (e.g., TeraTerm). |
| 45 | 8. Whatever sent from the serial port monitor will be echoed back then. |
