MIKROE-2380

ROTARY click From MikroElektonika Documentation Rotary click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 orange LEDs. The board is available in five different LED colors: red, green, blue, yellow and orange. Rotary click Features and usage notes Rotary click with its LED ring is a perfect solution for implementing an input knob into your design (in contrast to a potentiometer, a rotary encoder can be spun round continuously). A single rotation is divided into 15 discrete steps. The encoder outputs A and B signals (out of phase to each other). The knob is also a push-button outputted through the interrupt line. The LED ring are controlled through the SPI interface. Schematic also available in PDF (http://cdndocs.mikroe.com/images/a/a3/Rotary_O_click_schem In addition to the SPI lines (CS, SCK, MISO, MOSI), Rotary clicks have three additional lines for outputting the Encoder info: ENCB OUT, ENCA OUT and SW (in place of the standard AN, RST and INT pins, respectively). Rotary click All Rotary click boards can be used with either a 3.3V or 5V power supply. The configuration is set up with an onboard jumper (zero ohm resistor). By default, it’s set to 3.3V IC/Module [Rotary encoder surrounded by ring of LEDs] Interface SPI, ENCA, ENCB Programming Power supply 3.3V, 5V The following code snippet demonstrates the write procedure of Rotary click.
