Example serial test
This is a guide to the
serial C example project included in the EMAC OE SDK.
This application sets up and tests asynchronous IO on a serial port using poll() and fasync().
serial project builds one executable:
Opening, Building and Uploading the Project Files
1. Open the C/C++ editing perspective.
2. Open the project files.
3. Build the project.
4. Upload the executables to the target system.
Usage and Behavior
serial_test performs an asynchronous IO test on the specified serial device using either poll or FASYNC mode. It performs the test, reports, test, report, etc. It will keep running until it is stopped manually via CTRL-C.
It should run just fine on any device with a serial port.
./serial_test DEVICE -p|-a
- The serial device to use
- Use poll() for asynchronous IO
- Use FASYNC mode for asynchronous IO
