Pinguino – PIC microcontroller based Open Source



Pinguino is a PIC microcontroller based Open Source Hardware prototyping platform like Arduino ( AVR microcontroller based ). The Pinguino prototyping platform have a IDE same like Arduino, standard libraries and different prototyping boards to make it happens.

About Pinguino project

The Pinguino project was started in 2008 with a aim of making a Arduino like prototyping platform for PIC microcontroller.  In Arduino prototyping platform, the microcontrollers inside the boards doesn’t have a native USB interface on the chips. The Pinguno projects tries to overcome this problem with a PIC microcontroller with USB interface. Also the code length of Arduino programs in the old versions are littile messy.
The IDE of Pinguino is built with Python. At the beginning, an integrated preprocessor in Pinguino IDE translates specific Arduino instructions directly into C. This preprocessor reduces the code length and the execution speed and Pinguino hardware is based on a 18F2550. This chip has an integrated native USB module and an UART for serial link.

Pinguino IDE

Later the Pinguino IDE is become a stand alone application with a C compiler (SDCC), assembler and linker (GPUTILS) and a bootloader based on the PUF VASCO project.

Also now this Pinguino IDE is available for different operating systems like Windows, Mac os x and Linux. This IDE can support 8 bit and 32 bit Pinguino hardware.
We can download Pinguino IDE from Pinguino wiki page at here.

TTL/RS232

TTL, RS232, DCE, DTE......
This is where you can find informations and learn how to connect your Pinguino with a computer or a modem on a serial port.

The Pinguino serial I/O is TTL level ( 0..5V ). It can not be directly connected with an RS232 equipment.
If you want to connect it with a computer, wich is a DTE ( Data Terminal Equipment ), you need to build this converter:


This converter use only discrete components. NPN transistor can be used, such as 2N1711, 2N2222 etc...
Note that the DB9 connector is a female connector because DB9 on Data Terminal Equipment is always a Male connector.
This converter can be powered with a 3,3V or a 5V power supply.

If you want to connect Pinguino with a Modem, wich is a DCE ( Data Communication Equipment ), you need to build this version:


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.
