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.  ## 2.

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.  ## 4. Software Setup - [MPLAB X IDE ](https://www.microchip.com/en-us/tools-resources/develop/mplab-x-ide#tabs) - Version: 6.20 - XC8 Compiler v2.46 - MPLAB® Code Configurator v5.3.0 - PIC12-16F1xxx_DFP v1.3.90 - PIC18F-K_DFP v1.7.134 - [MPLAB X IPE v6.20](https://microchipdeveloper.com/ipe:installation) ## 5. Harmony MCC Configuration ### Getting started with MICRF TX CLICK with PIC16F1619(MCU) on Curiosity Development Board. | Tip | New users of MPLAB Code Configurator are recommended to go through the [overview](https://onlinedocs.microchip.com/pr/GUID-1F7007B8-9A46-4D03-AEED-650357BA760D-en-US-6/index.html?GUID-AFAB9227-B10C-4FAE-9785-98474664B50A) | | :- | :- | - Configure the following components in MCC Melody configuration as shown below. - Configure the INTERNAL OSCILLATOR as shown below.  - Configure the TMR4 as shown below.   - Configure the CRC as shown below.  - Configure the Pin Modules as shown below.  - Click on Generate once all the components are configured. - Connect the USB for programming the Device from MPLAB X IDE. ### Getting started with MICRF RX CLICK with PIC18F47K40(MCU) on Explorer 8 Development Kit. - Configure the following components in MCC Melody configuration as shown below. - Configure the System Module as shown below.   - Configure the Interrupt Module as shown below.  - Configure the CRC as shown below.   - Configure the TMR6 as shown below.   - Configure the ADCC as shown below.  - Configure the TMR4 as shown below.   - Configure the Pin Modules as shown below.  - Click on Generate once all the components are configured. - Connect the IDC 3 In-Circuit Debugger to program the device.. ## 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](https://microchipdeveloper.com/ipe:programming-device) 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](https://microchipdeveloper.com/mplabx:build). ## 7. Run the demo - After programming the board, the expected application behavior is shown in the below [video](https://github.com/MicrochipTech/Sub-GHz_MICRF112_MICRF220-219A/blob/main/docs/Working_Demo.gif). - 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.
