7.1 Demo Setup

The following steps explain the procedure for setting up the hardware for the three-phase sequence detection using the PIC18F56Q24 microcontroller.

  1. Insert the PIC18F56Q24 Curiosity Nano board in the Curiosity Nano slot of Curiosity Nano Base for Click boards.
    Note: For proper orientation while inserting the Curiosity Nano board, refer to the marking on the Curiosity Nano base board.
  2. Insert three Waveform Clicks in the three mikroBUS slots (slot 1, slot 2 and slot 3) available on the Curiosity Nano base board.
  3. Connect the SMA output of the Waveform Clicks to the respective microcontroller I/O pins using SMA connectors, as shown in Table 7-1.
  4. Connect the Waveform Click outputs to inputs of ADC and ZCD.
    • Signal-1 (waveform color - Red) of Waveform Click 1 to the RA0 (ADC AN0 input) and RC2 (ZCD2 input)
    • Signal-2 (waveform color - Green) of Waveform Click 2 to the RA1 (ADC AN1 input)
    • Signal-3 (waveform color - Blue) of Waveform Click 3 to the RA2 (ADC AN2 input) and RB0 (ZCD1 input)
  5. Connect the Curiosity Nano board to a host computer (PC) using the type-C USB cable.
  6. Refer to the Firmware section for firmware and hex file.
  7. To program application firmware on the microcontroller, refer to the PIC18F56Q24 Curiosity Nano Hardware User Guide.
