XNUT-105 Embedded communication computer with Ethernet and CAN
XNUT-105 is an open source, low-cost Ethernet single board computer with industrialized form-factor, DIN-rail enclosure, CAN interface and additional RS-232, RS-422 and RS-485 ports.
XNUT-105 is based upon the AVR AT90CAN128 CPU as it's core and the free open source RTOS and TCP/IP stack Nut/OS.
By using the freely available GNU GCC tool chain for Linux or Windows, and an open source TCP/IP stack, developers can quickly create custom CAN based Protocol Converter, Web Server and Fieldbus Gateway devices.
The perfect solution for equipment manufacturers who want to integrate
a Controller Area Network (CAN) into the world of
Ethernet and

Development
Applications are developed in the C programming language with the choice of either the free AVR-GCC compiler on Linux and Windows development hosts or the commercial ICCV7 compiler from ImageCraft.Nut/OS' architecture has been focused on portable standards. Developers with experience in C programming and TCP/IP applications for the PC will soon feel confident. Existing software can be adapted for Nut/OS with minimal effort. The following example prints a message on the second serial port:
#include <stdio.h>
#include <dev/uartavr.h>
int main(void)
{
FILE *ser1;
NutRegisterDevice(&devUart1, 0, 0);
ser1 = fopen("uart1", "r+b");
fprintf(ser1, "Hello world!\n");
}
The Nut/OS operating system offers a feature rich API including Multi-threading, Device Driver, Stream I/O, Dynamic Memory, Timer, Events, Socket API and TCP/IP Protocols. At the same time Nut/OS is a very lean OS which is well suited for microcontroller CPUs and their small memory footprint. Typically more than 100 KB program space and 20 KB data memory are available for your application. Nut/OS can be used in commercial products for any purpose without licence fees (the full BSD-style license is here). Nut/OS comes with several sample applications, including an embedded web server and a RS-232 to Ethernet gateway.
