PIC32 Bluetooth starter kit targets low-cost applications

August 06, 2014 // By Jean-Pierre Joosting
Microchip has announced a PIC32 Bluetooth® starter kit that eases development of low-cost Bluetooth-enabled products such as thermostats, wireless gaming controllers, barcode scanners and diagnostic tools.

The full-featured kit features a PIC32 microcontroller (MCU), HCI-based Bluetooth radio, Cree high-output multi-colour LED, 3 standard single-colour LEDs, an analogue 3-axis accelerometer, analogue temperature sensor and 5 push buttons for user-defined inputs. Additionally, the kit includes PICkit™ On Board (PKOB) which eliminates the need for an external debugger/programmer; USB connectivity; and GPIOs for rapid development of Bluetooth Serial Port Profile (SPP), USB and general-purpose applications. It 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 with a rich feature set including USB, I2S/SPI, mTouch® capacitive touch sensing and an 8-bit Parallel Master Port. 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 ideal for 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. Additionally, 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.
