PIC BASIC: GCBASIC FREE PIC BASIC for PIC microcontrollers

GCBASIC stands for Great Cow Basic why was it was named like this?...

I just don't know...

Anyway GCBASIC is a basic compiler for PIC microcontrollers and it is an open source project meaning that you can see all the source code and modify it if you want to (subject to keeping the existing license - basically any mods you make are subject to the same license).  

Note: They are also looking for some help in adding routines and documentation so if you find it useful why not add some yourself?

Open GCBASIC Site (for instructions and downloads).

The download links at that site do not work
The correct link to the GCBASIC download is:

http://www.sourceforge.net/projects/gcbasic/

(Hit the 'Download' drop down button).



GCBASIC is a true PIC Microcontroller compiler and not an interpreter so it means you can write fast code while still retaining the user friendliness of BASIC.  

Some benefits of this BASIC:

  • It's based on the syntax of QBASIC/FreeBASIC.
  • It can be assembled and run on almost all 10, 12, 16 and 18 series chips

It's not a polished integrated tool and there's no real IDE (although there is a user contributed one) that is quite basic but functional.

Note: There is information for setting up an editor for one button push hex file generation (the same as a commercial IDE - I have not tried this yet but  it looks promising).

I/O capabilities:

  • Standard 2x16 LCD routines
  • Routines for on-chip A/D, PWM, SPI, EEPROM and Timers
  • RS232 communications - rates between 300 and 19200 bps with user configurable parity, start and stop bits.
  • PS/2 keyboard reading
  • 4x4 Keypad

Output 

The GCBASIC compiler takes your basic program and generates an assembler output which you need pass through an assembler to get your desired hex file which you can then use in the normal way.
