1. Introduction

This application demonstrates the functionality of the MICRF TX CLICK module with a PIC16F1619 microcontroller and the MICRF RX CLICK module with a PIC18F47K40 microcontroller using Amplitude Shift Keying (ASK) modulation.

Transmitter Side:

  • The MICRF TX module transmits an incrementing counter value via ASK modulation at a frequency of 315 MHz.

  • This transmission is received by the MICRF RX module on the receiver side.

Receiver Side:

  • The received data's Received Signal Strength Indicator (RSSI) value and the total number of packets received are displayed on an LCD screen.

  • By pressing the user button S1, the LCD switches to display engineering data, which includes error counts, CRC (Cyclic Redundancy Check) information, protocol failures, and buffer overflow statistics.

3. Hardware Setup

MICRF TX CLICK with PIC16F1619(MCU) on Curiosity Development Board.

Step 1 - Replace the default MCU of Curiosity Development Board with PIC16F1619.

Step 2 - Connect the Jumper J12 to 3.3V/5V based on the MCU(here PIC16F1619 has Operating voltage range 2.3V to 5.5V).

Step 3 - Connect the MICRF TX CLICK Board to the MIKROE BUS Connector as shown below.

MICRF RX CLICK with PIC18F47K40(MCU) on Explorer 8 Development Kit.

Step 1 - Replace the default MCU of Explorer 8 Development Kit with PIC18F47K40.

Step 2 - Connect the MICRF RX CLICK Board directly into J35 Jumper (MIKROE BUS Connector).

Step 3 - Power Explorer 8 from J1, the 9V power adapter, not from USB.

Step 4 - Verify all the Jumper connection of the Explorer 8 Development Kit as shown below.

6. Board Programming

Programming hex file:

Program the precompiled hex file using MPLAB X IPE

  • The Precompiled hex file is given in the hex folder. Follow the steps provided in the link to program the precompiled hex file using MPLABX IPE to program the pre-compiled hex image.

Build and program the application using MPLAB X IDE

The application folder can be found by navigating to the following path:

  • "Transmitter/MICRF_TX.X"

  • "Receiver/MICRF_RX.X"

Follow the steps provided in the link to Build and program the application.

7. Run the demo

  • After programming the board, the expected application behavior is shown in the below video.

  • The MICRF TX CLICK is a transmitter which sends the incremented counter value and whenever the data is transmitted the D7 led glows.

  • The MICRF RX CLICK is a receiver which receives the data from the MICRF TX and displays the data received along with RSSI value.
