The built-in IO application gives you simple control over all 28 I/O pins. Individually set each pin as an output high, output low, input, or input with built-in pullup resistor. Just click on the radio buttons! Red and green indicators show you whether each pin is high or low.

The built-in STEPPER application is a controller for a stepper motor. You will have to provide an external stepper motor driver (both phase/enable and step/direction drivers are supported), but we take care of the rest. Linear acceleration and deceleration, support for microstepping drivers, conversion factors for linear actuators, and PWM current control are just some of the features in this application.

The built-in PULSES application can generate periodic square waves with varying frequency and duty cycle, as well as single-shot pulses. Use this application to experiment with servo motors, vary the speed of DC motors, vary the brightness of LED’s, generate audio tones, and generate pulse-width modulation (PWM) waveforms for a wide variety of applications. The applicaton includes three independent pulse generators.

The built-in TERMINAL application lets you talk to any application using a text-based interface. All of our built-in applications support command-line control (for example, see the command-line help for the IO application in the figure on the right). You can also use our TERMINAL application for interacting with your own custom programs.

Develop your own custom applications in C using AVR development tools such as the open-source WinAVR. Then, just type in your HEX file name, press the Install button, and our program installs your application. It couldn’t be easier.
