Orangutan X2 blinking LED demo (AVR Studio project) (11k zip)

C code for the mega644: This simple project sequentially blinks the X2’s five user LEDs. It does not require any other code libraries.

Orangutan X2 SPI wrapper functions v1.00 (12k zip)

C code for the mega644: These C functions are high-level implementations of the low-level commands detailed in the Orangutan X2 command documentation. They let you easily control the X2’s auxiliary mega168 microcontroller and hence most of the X2’s onboard hardware (e.g. motors, buzzer, and UART). They also provide an example you can build on to create your own custom high-level command wrappers. This code is compatible with all firmware versions.

Orangutan X2 SPI wrapper functions v1.01 (12k zip)

C code for the mega644: Version 1.01 of the SPI wrapper functions takes advantage of the improvements introduced by firmware upgrade v1.01. These SPI wrapper functions are compatible with all firmware v1.01 and higher.

LCD control functions (3k zip)

C code for the mega644: These functions give you everything you need to control an LCD with your Orangutan X2. The file LCD.c requires the delay functions defined in the Orangutan X2 SPI command wrappers above.

Orangutan X2 test code (AVR Studio project) (68k zip)

C code for the mega644: We use this program to test each Orangutan X2 before it ships, and as such it is the program that comes pre-loaded on every X2. The ports test enables pull-ups on ports A and D (the 16 user IO pins on the right side of the board) and displays the pin values on the LCD. The motor test sets motor speed and direction based on the position of the user trimmer pot. This project requires the LCD control functions and Orangutan X2 SPI command wrappers above.

Orangutan X2 melody demo (AVR Studio project) (43k zip)

C code for the mega644: This project demonstrates how you can use the auxiliary mega168 microcontroller to play melodies while leaving the main mega644 microcontroller free to control your robot. It requires the LCD control functions and Orangutan X2 SPI command wrappers above.
