UART Select Example
The UART select example is for demonstrating the use of select() for
synchronous I/O multiplexing on the UART interface. The example waits for a
character from UART using select() until a blocking read without delay or a
successful non-blocking read is possible.
Please note that the same result can be achieved by using uart_read_bytes()
but the use of select() allows to use it together with other virtual
file system (VFS) drivers, e.g. LWIP sockets. For a more comprehensive example
please refer to system/select.
See the README.md file in the upper level 'examples' directory for more information about examples.
