Serial port C / C++ lib

[Bogdan Teodorescu]

Hello

I want to use BBB to read serial devices with serial Modbus protocol. Is there a library to include in C/C++ code to read/write from serial port (actually

USB adapter ttyUSB0), better a Modbus library for the serial port.

Thanks a lot

Bogdan

Hi Bogan,

I have a C++ SerialPort class in the following files:
https://github.com/dhylands/projects/blob/master/common/SerialPort.h
https://github.com/dhylands/projects/blob/master/common/posix/SerialPort.cpp
https://github.com/dhylands/projects/blob/master/common/mingw/SerialPort.cpp

The file in the posix directory is for linux. The file in the mingw directory is for win32.

I also have some generic linux serial test code here:
https://github.com/dhylands/projects/tree/master/host/sertest
https://github.com/dhylands/projects/tree/master/host/sertest-select

I've never coded for Modbus, so I don't know if there is missing functionality or not.

Hi,

We use libmodbus supporting MODBUS-RTU and -TCP: http://libmodbus.org/

Cross-Compiling it for ARM works fine with (tweak it for your own
toolchain):

./configure --host=arm-angstrom-linux-gnueabi --build=x86_64 ...
