# MPLAB® Harmony 3 Standalone IEEE 802.15.4 Physical Layer

MPLAB® Harmony 3 is an extension of the MPLAB® ecosystem for creating embedded firmware solutions for Microchip 32-bit SAM and PIC® microcontroller and microprocessor devices.  Refer to the following links for more information.

- [Microchip 32-bit MCUs](https://www.microchip.com/design-centers/32-bit)
- [Microchip 32-bit MPUs](https://www.microchip.com/design-centers/32-bit-mpus)
- [Microchip MPLAB X IDE](https://www.microchip.com/mplab/mplab-x-ide)
- [Microchip MPLAB® Harmony](https://www.microchip.com/mplab/mplab-harmony)
- [Microchip MPLAB® Harmony Pages](https://microchip-mplab-harmony.github.io/)

This repository contains the MPLAB® Harmony 3 Module for Standalone IEEE 802.15.4 Physical Layer that provide an interface to the microcontrollers (like SAML21, SAMD21) to access the transceiver functionality of radio transceivers like AT86RF233, AT86RF212B & AT86RF215. 
With the help of PHY layer module user can enable various functionaities of the transceiver.

- Clone the [wireless_15_4_phy_trx](https://github.com/MicrochipTech/wireless_15_4_phy_trx) repo to user's local Harmony Repo.
- Refer to the section 2.5, Creating a New MCC Harmony Project in the [PIC32CXBZ2 Application Developer's Guide](https://onlinedocs.microchip.com/g/GUID-A5330D3A-9F51-4A26-B71D-8503A493DF9C).
- Project Graph appears with some predefined component as shown in image below:

![](docs/img1.jpg)

- The IEEE 802.15.4 PHY TRX component will appear under Wireless->Drivers->IEEE 802.15.4 in the Device Resources tab as shown in image below:

![](docs/img2.png)

- Select MiWi (if MiWi protocol is used as higher layer) under “Wireless->Drivers” tab. Accept all Dependencies or satisfiers, by selecting "Yes". All the necessary components will be auto populated.
- Please follow the steps in the following [link](https://github.com/MicrochipTech/MiWi/blob/main/docs/GUID-32628D58-8B41-490F-8DA4-520C34856980.md) to configure for MiWi.

- Connect SERCOM5 and TC0 dependencies as shown in the image below:

![](docs/img3.png)

- Finally ensure that the project graph has all the components as depicted below.

![](docs/img4.PNG)

- Please follow the below steps for the “Configuration Options” changes to be done for Standalone PHY layer.
- Go to Plugins>Pin Configuration. Refer below image for the Pin configurations. Provide the same “Custom Name”, “Function” and “Direction” as depicted in image below.

![](docs/PinCfg1.PNG)

![](docs/pinCfg2.PNG)

- The “Module Pin Selections” in the “Configuration Options” gets automatically populated when the correct pin configurations are configured.
- The Radio transceiver type can be changed by selecting the dropdown option availabel in “Select Transceiver Type”. At present only RF233 ans RF212B is supported.

![](docs/phy_configuration.PNG)

- Following are the EIC and Sercom5 configuration.

- Click on “Resource Management [MCC]” and click “Generate”.

![](docs/mcc_code_gen.jpg)

Note 1: After generating the code via MCC, make sure to implement the following changes. Right click on the project and go to properties. Select xc32-gcc. Under the option categories, select Preprocessing and Messages. 
Double click on the Preprocessor macros and add the symbol, PHY_AT86RF212B/PHY_AT86RF233/RF215V3 depending on the preference. Remove ENABLE_NETWORK_FREEZER & Chimera_SOC symbol if MiWi is used.

Note 2: To optimise the NVIC priority levels of different peripherals used such as EIC, SPI and TC, go to project source files>config>default>peripheral>plib_nvic.c, change the NVIC priority as shown in the image below:

![](docs/nvic_priority.PNG)

Note 3: In app.c file replace "appData.appQueue = xQueueCreate( 64, sizeof(APP_Msg_T) );" with "appData.appQueue = xQueueCreate( 5, sizeof(APP_Msg_T) );"

Note 4: The following applies if MiWi protocol is used as higher layer : In the file tasks.c replace "#define TASK_MIWI_STACK_SIZE (8 *1024 / sizeof(portSTACK_TYPE))" with "#define TASK_MIWI_STACK_SIZE (2 *1024 / sizeof(portSTACK_TYPE))"

Note 5: The size of lAPP_Tasks should be changed to 512 in task.c file.
