The STM32 platform integrates a MCU, a BLE transmitter(BlueNRG), and several sensors. All the chips are manufactured by STMicroelectronics.

This repository includes a comprehensive SDK, together with various software resources like drivers, middlewares, and application demos for further developments.

##Cannon

• Cannon is the very first development board we made for STM32 platform.
• Cannon boards allow anyone to try out new ideas and to quickly create product prototypes.
• Learn hardware specs at here.
• Learn step-by-step tutorial at here.
• Learn software API manuals at here.

Cannon is FREE now! Apply for a Free Cannon at JUMA's forum.

##Quick Start

1. Choose Demo project
   Learn demos under /product folder, select and open one project in Keil.

2. Learn how to Compile
   Cannon board has two versions, select the right one in Keil compile option.
   Make sure all the header files are included.

3. Learn how to Download firmware
   Connect Cannon to computer via J-Link or ST-LINK.
   Download firmware to Cannon.

4. Work with BLE APP
   A debugger APP (/tools/JumaBleHelper.apk) is offered to facilitate BLE development. It can be installed and run on Android machine to transmit BLE raw data to/from Cannon.
   The iOS version can be downloaded in AppStore as well.

You can get detailed tutorial at here.
