Hey, please see alpha release of Serial I/O package.
I am looking for any comments on code style, usability, naming etc. Also,
it would be great if people could reply on which platforms
they successfully (and not, which is more important) tested it. Sorry but
Windows is not yet supported.
Currently open flags are hardcoded to: O_RDWR | O_NOCTTY | O_SYNC, as I yet
to decide what is the best way to maintain cross-platformability and ease
of use (e.g. using string for parity setting and then doing switch
according to platform being used instead of making the same flags from
different platforms global to Octave), comments are welcome.
Also, a simple example to get started (for testing adapter's RX and TX
lines are connected together):
s0 = serial() # Opens default serial port ttyUSB0 in default configuration
of 115200, 8-N-1
s1 = serial("/dev/ttyUSB1", 115200) # Opens serial port ttyUSB1 with
baudrate of 115200 (config defaults to 8-N-1)
srl_flush(s1); # Flush input and output buffers
srl_write(s1, "Hello world!") # Blocking write call, currently only accepts
strings
data = srl_read(s1, 11) # Blocking read call, returns uint8 array of
exactly 11 bytes read (data = [72 101 108 108 111 32 119 111 114
108 100])
char(data) # Converts uint8 array to string, (ans = "Hello world", note: no
exclamation mark)
srl_baudrate(s1, 9600) # Change baudrate
srl_bytesize(s1, 5) # Change byte size (config becomes 5-N-1)
srl_parity(s1, "E") # Changes parity checking (config becomes 5-E-1),
possible values [E]ven, [O]dd, [N]one.
srl_stopbits(s1, 2) # Changes stop bits (config becomes 5-E-2), possible
values 1, 2.
s2 = serial("/dev/ttyS0", 9600, 6, "odd", 2) # Opens serial port ttyS0 in
9600, 6-O-2 configuration
srl_close(s0) # Closes and releases file descriptor
