Stellarino is a simple Wiring-like but incompatible interface library implemented in C for the TI Stellaris LM4F120H5QR used in the Stellaris Launchpad, and similar MCUs. It is meant to facilitate the rapid creation of basic microcontroller firmware without the need to parse through thousands of pages in datasheets and other documentation. It uses syntax similar to Wiring to ease the introduction of newcomers familiar with the Arduino and similar boards to the Stellaris platform.
Stellarino implements functions for configuration, delays, using timers, GPIO, analog input, PWM, controlling hobby-style servomotors, and more. It was created using the TI StellarisWare Peripheral Driver Library. It thus requires StellarisWare and a suitable IDE, such as TI Code Composer Studio in order to function. Since Stellarino implements all basic functionality using the StellarisWare PDL with simple, easy to understand code, it also makes a good introductory example for the use of the PDL.
Stellarino 0.4 is the first public release of Stellarino.
Stellarino is free software, distributed under version 3 of the GNU General Public License. It links with the StellarisWare PDL, which is permissible due to the BSD-style license on the PDL.
The library also includes code to configure the very useful UARTstdio library provided by TI. However, the UARTstdio library is under a restrictive GPL incompatible license and thus cannot be directly included with Stellarino. To use UARTstdio with this library for personal use, uncomment the associated #include in stellarino.h, copy uartstdio.c from the "utils" folder of StellarisWare to the root of the project directory, and uncomment the UARTStdioInit(0); line from the init() function defined in stellarino.c.
The download is provided as a TI Code Composer Studio project. Documentation for the library is included with the project in the file stellarino_userguide.txt.
