Linux Simple I/O Library

libsimpleio is an attempt to encapsulate (as much as possible) the ugliness of Linux I/O device access. It provides services for the following types of I/O devices:

Industrial I/O Subsystem A/D (Analog to Digital) Converter Devices
Industrial I/O Subsystem D/A (Digital to Analog) Converter Devices
GPIO (General Purpose Input/Output) Pins
Raw HID (Human Interface Device) Devices
I²C (Inter-Integrated Circuit) Bus Devices
Labview LINX Remote I/O Devices
PWM (Pulse Width Modulated) Output Devices
Serial Ports
SPI (Serial Peripheral Interface) Bus Devices
Stream Framing Protocol Devices
TCP and UDP over IPv4 Network Devices
Watchdog Timer Devices

Although libsimpleio was originally intended for Linux microcomputers such as the Raspberry Pi, it can also be useful on larger desktop Linux systems.

The C wrapper functions exported by libsimpleio all follow the same uniform pattern:

All C wrapper functions are proper procedures (void f() in C).
All input arguments of primitive types (int, float, etc.) are passed by value.
All output arguments of primitive types are passed by reference (int *, float *, etc.).
All composite types are passed by reference.
int32_t is used wherever possible for int and bool arguments.

All of the C wrapper functions are declared between _BEGIN_STD_C and _END_STD_C for C++. Binding modules are provided for Ada, C++, C#, Java, and Free Pascal. Additional source code libraries are provided for Ada, C++, C#, Java, and Free Pascal that define OOP (Object Oriented Programming) classes for libsimpleio.

News

9 January 2019 -- Continued working on the Ada Remote I/O code. Continued working on the Pascal Remote I/O code. Compiling Pascal Remote I/O client programs on Windows is now supported.
16 January 2019 -- The C wrapper function source files have been moved to the c/ subdirectory. The source code is now published on GitHub at https://github.com/pmunts/libsimpleio. The old repository at http://git.munts.com (which actually just mirrors a private Subversion repository and then pushed to GitHub) will be maintained, but you should clone from GitHub, which will be much faster.
8 February 2019 -- Reworked PWM device handling for the Linux 4.19 kernel. Cleaned up some stale links and commands in the user manual. Cleaned up some loose ends in the MY-BASIC bindings and example programs.
12 March 2019 -- The Debian native packages now depend on libhidapi-dev, for Remote I/O over USB raw HID.
