1- Product Description
The Round Solutions PingPong is an embedded IoT/M2M hardware platform made for Software Developers. The platform supports extension boards that add unlimited capabilities. It can be used to easily make physical devices that connect to the web. It’s literally plug, push and play. PingPong comes with both wired and wireless connectivity. The device is available in two open­source SW versions. While the RTOS version comes with the world’s fastest 32-bit microcontroller running in C/C++, the Linux version uses the powerful ARM Cortex processor for even more functionality and applications. PingPong base circuit boards also have a high speed Telit cellular module, a high accuracy positioning component for the Global Navigation Satellite System (GNSS), Ethernet, USB, CANBUS among other items. The Evaluation Kit comes with a dedicated M2M/IoT SIM card and connectivity to a cloud platform.
2- Key Benefits

5- Development Enviroment:
The RTOS version of the PingPong board uses the Microchip PIC32MZ2048ECM144 microcontroller. MPLABX from microchip along with XC32 complier are the IDE and complier used in developing applications and modifying the firmware. Both the IDE and the complier can be downloaded from
Microchip’s website. The IDE is free of charge and the complier comes with 60 days free trial and
then a license can be purchased or can be used for free with some limitations.
Microchip MPLABX: http://www.microchip.com/pagehandler/en-us/family/mplabx/
Microchip XC32 Complier: http://www.microchip.com/pagehandler/en_us/devtools/mplabxc/
It is also strongly recommended to download Microchip MPLAB Harmony Integrated Software Framework. Microchip MPLAB Harmony allows the developer to configure the project to use different stacks and configures peripherals easily. It can be found on this link:
http://www.microchip.com/pagehandler/en-us/devtools/mplabharmony/home.html
Refer to Installing a Plug-in Module inside the MPLAB Harmony help file for a guide to add it as a plug in to the MPLABX IDE.
MPLAB Harmony comes with a set of examples that demonstrates the use of all the peripherals. All examples can be configured to use the Microchip PIC32MZ2048ECM144 microcontroller by changing it from the project properties, and then launching the MPLAB Harmony configurator to generate compatible code for the new Microcontroller without deleting any of the added code such as USB descriptors.

6- Downloading Firmware to the PingPong board:
a- PIC Programmer:
The PingPong board has 5 SMD pins for downloading a firmware to the microcontroller on board. The pins are referenced in the picture below and are from right to left: Master clear (MCLR), VDD, GND, PGD, and PGC. A non-expensive programmer is Microchip PicKit3 programmer which can be used to download the firmware. Pinouts are shown below. Other programmer and emulators such as ICD3 and REAL ICE are available from Microchip for extensive debugging.
Fig (a)
The Microchip PICKit3 is integrated with MPLABX and the firmware can downloaded directly from the IDE when it is connected to it.
b- USB Boot Loader:
Alternatively, hex files can be downloaded via USB CDC. Digital input 4 (DI4) has to be tied to ground to lunch the Boot Loader in the PingPong on power up. The Bootloader software is used to download hex files. The steps are Connect Load Hex File Erase Program Verify. As USB CDC creates a virtual COM Port, the user has to select the proper COM port and set the baud are to 115200 for prompt download of hex files. Fig (b)
Once Connect is clicked, the application requests the version of the boot loader inside the PingPong. The current version should be higher than 1.4. Hex files that will be downloaded with the Projects output that will be downloaded using the Bootloader should have their the linker script
