u-blox
This class provides an API to communicate with a u-blox GNSS chip. The files here were originally part of the C027_Support library (https://developer.mbed.org/teams/ublox/code/C027_Support/ at revision 138:dafbbf31bf76) but have been separated out, primarily for use on the u-blox C030 board where the cellular interace portion of the C027_Support library will instead be provided through the new mbed Cellular API.

Member Function Documentation
| int get | ( | void * | buffer, |
| int | length, | ||
| bool | blocking | ||
| ) |
read a buffer from the serial port
- Parameters:
-
pointer to the buffer to read. length number of bytes to read blocking true if all bytes shall be read. false if only the available bytes.
- Returns:
- the number of bytes read.
Definition at line 113 of file serial_pipe.cpp.
| int getc | ( | void | ) |
receive one character from the serial port (blocking)
- Parameters:
-
the character received
Definition at line 104 of file serial_pipe.cpp.
| int put | ( | const void * | buffer, |
| int | length, | ||
| bool | blocking | ||
| ) |
send a buffer
- Parameters:
-
buffer the buffer to send length the size of the buffer to send blocking,if true this function will block until all bytes placed in the buffer.
- Returns:
- the number of bytes written
Definition at line 47 of file serial_pipe.cpp.
| int putc | ( | int | c ) |
send a character (blocking)
- Parameters:
-
c the character to send
- Returns:
- c
Definition at line 40 of file serial_pipe.cpp.
| int readable | ( | void | ) |
check if readable
- Returns:
- the size available in the buffer.
