C MEX serial port

C MEX interface for serial port by implementing c_serial code base: https://github.com/rm5248/CSerial

Install

On Nelson >= 0.4.6 :

nmm('install', 'https://github.com/NelsonModules/cserial.git#master')

On Scilab 6.1:

atomsInstall('cserial')

Build

On Nelson >= 0.4.6 :

run('builder.nls');
run('loader.nls');
doc cserial

On Scilab 6.1:

exec('builder.sce');
exec('loader.nls');

On Octave or Matlab:

run('builder.m')

Builtin availables:

• getPortNames() returns a cell with available ports.

• id = openPort(port, baudrate [, databits [, stopbits, [parity, [flowcontrol, [rtscontrol]]]]])

  • supported baud rate: 0, 50, 100, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 115200, or 921600.
  • data bits: 5, 6, 7, or 8.
  • stop bits: 0 or 1.
  • parity: 'none', 'odd' or 'even'.
  • flowcontrol: 'none', 'hard' or 'soft'.
  • rtscontrol: 'none', 'hard', 'soft', or 'best'.

• [data, nbBytesReceived] = readPort(id, numBytesToRead) read data from port.

• writePort(id, data) write data on serial port. data must be uint8 or char.

• closePort(id) closes an port opened.

• flushPort(id) flushs desired port.

• st = getPortConfig(id) returns struct with port informations.

This toolboxe is an good example to show how it is easy to use existing C MEX builtin with Nelson. This toolbox works on Nelson and all others tools fully compatible with C MEX API.
