Compatibility Pinguino vs. Arduino

Pinguino boards can be programmed using a Python IDE which is available as a FREE download.

We use as much as possible the Arduino syntax and we try to supply equivalent libraries.

Some libraries are still under development by the Pinguino Dev. Team (Ethernet & Android ADK) and some others will not be supported due to a lack of time or a lack of interest (SoftwareSerial, Matrix & Sprite). You're welcome to provide these "unsupported" libraries to the community ;o)

Most of the libraries are enriched with specific Pinguino instructions (for example, you can use Serial.printf with the Serial library).

32-bit Pinguino programs are compiled with a C/C++ Compiler which is a GNU-Mips toolchain based on GCC 4.5.2, binutils 2.21 and Newlib 1.19.

8-bit Pinguino uses the SDCC 3.2.1 compiler which is only for C language. As Arduino mainly uses C++ there are necessarily substancial differences versus Pinguino.
