M-Bus Library Support
The powerful embedded computer CX255 is a freely programmable and
configurable Linux computer. The integrated M-Bus interface is supported
by a C library for easy reading electricity, gas and water meters. The
software integration into a specific environment can be realized with minimum effort. An exchangeable SD card offers up to se veral Gigabytes of
nonvolatile mass storage space for universal usage. It can be used for
databases, for datalogging or even for larger programs or libraries. All
common file formats like FAT, FAT32, ext2, ext3, among others, are
supported.
Flexible programmable platform
The C/C++ programming is supported by a standard GC C toolchain with
Glibc library. Script programs are supported as well as a Java runtime
machine. Application programs benefit from the numerous protocols,
servers and clients already available for instantaneous usage. A CGI enabled webserver supports webbased applications, data transfer can comfortably be done by ftp transfer and data management is supported by the SQL
database system SQLite.
