Bluetooth development kit for PIC 32 users

August 07, 2014 // By Graham Prophet
Microchip’s PIC32 Bluetooth starter kit is intended for projects such as thermostats, wireless gaming controllers, barcode scanners and diagnostic tools. The kit integrates a PIC32 MCU with LEDs, analogue sensors, user-defined push buttons, USB and I2S/SPI connectivity and mTouch capacitive touch sensing.

As well as the PIC32, there is an HCI-based Bluetooth radio, Cree high-output multi-colour LED, three standard single-colour LEDs, an analogue 3-axis accelerometer, analogue temperature sensor and five push buttons for user-defined inputs. The kit includes PICkit On Board (PKOB) which eliminates the need for an external debugger/programmer; USB connectivity; and GPIOs for development of Bluetooth Serial Port Profile (SPP), USB and general-purpose applications. The starter kit also features a plug-in interface for an audio CODEC daughter card which is set to release at a later stage to support Bluetooth audio.

The Bluetooth Starter Kit includes a PIC32MX270F256D MCU for main processing that runs at 83 DMIPS with 256 kB Flash and 64 kB RAM. The kit reduces software development time by offering a free Bluetooth SPP stack optimised for the on-board PIC32 MCU for setting-up emulated serial port connections between two peer Bluetooth devices.

The Bluetooth Starter Kit is targeted at low-cost applications in the consumer market such as Bluetooth thermostats and wireless gaming controllers. In the medical and industrial markets, applications include blood glucose meters, wireless diagnostic tools, Bluetooth GPS receivers, Bluetooth serial adapters and cordless barcode scanners.

The PIC32 Bluetooth Starter Kit is supported by Microchip's free MPLAB X Integrated Development Environment (IDE) and MPLAB Harmony Integrated Software Framework. The free Quick Start Package is available today, featuring an Android application development environment. It also includes a free Software Development Kit (SDK) with the application source and binary code for Microchip’s Bluetooth SPP library. Both are optimised for the on-board PIC32 MCU, and are available today via free download. The PIC32 Bluetooth Starter Kit (DM320018) is priced at $79.99.
