Diese Zusatzplatine verfügt über den 2765 Mini-2-Achsen-Analogausgangs-Thumbstick von Adafruit Industries und bietet Ihnen einen „selbstzentrierenden“ Analog-Joystick mit einer schwarzen Kippkappe ähnlich den PSP-Joysticks.
Präzise Steuerung mit 10kΩ Potentiometern
Das Joystick 3 Click Board™ ist mit zwei 10-kΩ-Potentiometern ausgestattet, eines für Aufwärts-/Abwärtsbewegungen und eines für Links-/Rechtsbewegungen. Diese Potentiometer gewährleisten eine genaue und präzise Steuerung, wodurch sich dieses Click Board™ perfekt für verschiedene Anwendungen wie Mensch-Maschine-Schnittstellengeräte (HMI), Robotik und andere Steuerschnittstellen eignet.
Nahtlose Verbindung mit mikroBUS™
Das Joystick 3 Click Board™ lässt sich über den 12-Bit-A/D-Wandler MCP3204 nahtlos mit mikroBUS™ verbinden. Dies gewährleistet eine schnelle und effiziente Datenübertragung und ermöglicht Ihnen eine reibungslose und reaktionsschnelle Steuerung.

How Does The Joystick 3 Click Board™ Work?
The Joystick 3 Click Board™ is based on the 2765, a high-quality mini 2-axis analogue-type thumbstick from Adafruit Industries. This type of joystick has a self-centring feature that allows it to centre itself the moment when you release the joystick. It also contains a comfortable cup-type black knob/cap, which gives the feel of a thumbstick, making it very similar to the 'analogue' joysticks on PSP joysticks, suitable for numerous applications as a human-machine interface.
The Joystick 3 Click Board™ comprises two 10kΩ potentiometers, one for up/down and another for left/right direction, used as dual adjustable voltage dividers providing 2-axis analogue input in a control stick form. With the joystick fully assembled and functioning, the voltage will follow the motion of the thumbstick as it is moved around.
The measurements of the potentiometer resistance change are needed to read the joystick's physical position. That's why the MCP3204, a 12-bit A/D converter from Microchip, connects the joystick with mikroBUS™ using a simple serial interface compatible with the SPI protocol to determine the value of the joystick's X and Y. As the MCP3204 has a resolution of 12 bits, the values on each analogue channel (axis) can vary from 0 to 4095. So, if the stick is moved on the X axis from one end to the other, the X values will change from 0 to 4095, and a similar thing happens when moved along the Y axis. The value of the joystick staying in its centre position is around 2048. Also, the MCP3204 is capable of conversion rates of up to 100ksps.
The Joystick 3 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
