Pmod JSTK2 Two-Axis Joystick


With a two-axis joystick on a center button, a trigger button, and a programmable RGB LED capable of 24-bit color, the Digilent Pmod JSTK2 is ideally suited for embedded or digital systems that require proportional control from the user, such as robotic applications. The Pmod JSTK2 utilizes two potentiometers oriented orthogonally to one another and are manipulated by moving the joystick in the X and Y directions. As the joystick moves, the voltage output at the sweep pin of each potentiometer changes and is measured by the 10-bit ADC present on the embedded PIC16F1618 microcontroller. The raw measured data is stored at a rate of 100 Hz as a 16-bit right-justified variable in RAM with the upper 6 bits masked with zeros.
