Programming and Operating the LED Sign

Created on: 27 September 2012

Source code files for Atmel Studio 6 are available for download as well as a set of files that can be used in Linux (find the files below).

Both these sets of files are written in the C programming language and both do the same thing – they flash the LEDs of the sign through various on/off sequences.

Project Source Code

These source code files can be modified to make your own preferred flashing sequence of LEDs.

Atmel Studio 6 project: LED_sign_controller.zip

Linux / make project: Open_Sign.zip or Open_Sign.tar.gz

Programming the Sign

Use a programmer such as the AVRISP mkII (ATAVRISP2) from Atmel to program the board. This programmer must be plugged into the 6-pin header of the controller board. Pin 1 of the header is marked on the silkscreen of the board with a triangular arrow.

The same steps used in the Starting AVR 8-bit Development tutorial can be used to modify, compile and load the program to the controller board if using the Atmel Studio development tools in Windows.
