BASCOM-AVR Overview

Latest revision as of 20:54, 4 February 2014

BASCOM-AVR© is the original Windows BASIC COMPILER for the AVR family. It is designed to run on XP/VISTA/WIN7 and WIN8'

This product description is updated in 2014. But we do not change it each time we update the software. In the online help you can find a list of all statements and functions.

Key Benefits

• Structured BASIC with labels.
• Structured programming with IF-THEN-ELSE-END IF, DO-LOOP, WHILE-WEND, SELECT- CASE.
• Fast machine code instead of interpreted code.
• Variables and labels can be as long as 32 characters.
• Bit, Byte, Integer, Word, Long, Single, Double and String variables.
• Large set of Trig Floating point functions.
• Date & Time calculation functions.
• Compiled programs work with all AVR microprocessors that have internal memory.
• Statements are highly compatible with Microsoft’s VB/QB.
• Special commands for LCD-displays , I2C chips and 1WIRE chips, PC keyboad, matrix keyboad, RC5 reception, software UART, SPI , graphical LCD, send IR RC5,RC6 or Sony code.
• TCP/IP with W3100A/W5100/W5200/W5300 chips.
• Built in AVR-DOS functions like MKDIR, CHDIR, DIR, OPEN, CLOSE, etc. Just as they work in  QB/VB !
• Local variables, user functions, library support.
• Integrated terminal emulator with download option..
• Integrated simulator for testing.
• Integrated ISP programmer (application note AVR910.ASM).
• Integrated STK200 programmer and STK300 programmer. Also supported is the low cost Sample Electronics programmer. Can be built in 10 minutes! Many other programmers supported via the Universal Interface.
• Many supported programmer like STK500, STK600, MKII, USBASP, JTAG , Arduino
• Editor with statement highlighting.
• Context sensitive help.
• DEMO version compiles 4KB of binary code. Well suited for the ATmega48.
• English an German Books available
• AT mouse simulator, AT keyboard simulator, I2C Slave available as add on.
• This product is developed in 1995 and is updated regularly.

And many other functions, statements and directives

To make a program takes just a few steps :

• Write the program in BASIC
• Compile it to fast machine binary code
• Test the result with the integrated simulator(with additional hardware you can simulate the hardware too).
• Program the chip with one of the integrated programmers.
  (hardware must be purchased separately)

This is a screen shot of the editor. You can work in normal mode or project mode.

At the left you find the Code Explorer. The Code explorer can show unused data in a different colour.

When the Code Explorer is visible, the editor supports Proper Indent and Indent drawing.

Indent lines can be a great visual help.

A tool tip with info can be shown by pressing SHIFT :

Here it is clear that BDIL is a byte variable, dimensioned in the module CAN-Elektor.bas

It will show info for constants, aliases, variables and functions.
