The Robostix expansion board has limited resources both in terms of hardware and software. The programs must be written in C and then cross compiled on an external computer, transfered to the main processing unit(Gumstix) and then uploaded to Robostix through the serial port on which it is connected to the main processing module(Gumstix). The environment in which the code will execute does not have large sets of libraries due to its limited memory. Hence standard POSIX functions will not be available.
