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.

Key functions
-
joystick3_read_raw_adcThis function reads the raw ADC for X and Y axis by using SPI serial interface. -
joystick3_get_angleThis function calculates and returns the joystick angle in degrees from raw ADC values for X and Y axis. -
joystick3_get_positionThis function calculates and returns the joystick position flag from raw ADC values for X and Y axis.
Example Description
This example demonstrates the use of the Joystick 3 Click Board™ by reading and displaying the raw ADC for the X and Y axis, as well as the joystick angle and position calculated from those ADC readings.

Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click, or RS232 Click to connect to your PC for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
MIKROSDK
The Joystick 3 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
