##Introduction The STM32 platform integrates a MCU, a BLE transmitter(BlueNRG), and several sensors manufactured by STMicroelectronics.

This repository includes a comprehensive SDK together with various software resources like drivers, middlewares, examples for STM32 platform development.

##Cannon

• Cannon is one of the development boards belongs to STM32 platform.
• Cannon boards allow anyone to try out new ideas and to quickly create prototypes.
• Learn hardware specs at: http://www.juma.io/platform/cannon.html
• Learn software usages at: http://www.juma.io/doc/zh/boards/st/cannon.html
• Learn software API manuals at: http://www.juma.io/doc/zh/embedded_sdk.html
• Get a Cannon board at JUMA's Taobao shop: http://tao.bb/5Dh6u

##Directories

• /product - several examples based on Cannon, including a Thermometer detector, a BLE echo appliction, a SensorTag, etc.
• /system - including drivers, HALs, middlewares, JUMA SDKs, etc.
• /tool - including some APP utilities which could be installed and run on Android mobiles.
• /document - things like document, datasheet, manuals, etc.

##Quick Start

1. Choose seed project
   Learn examples under /product folder, select one to be the seed project.
   Copy & paste it to create your own project.

2. Header files
   Remember to include necessary header files.
   For BLE, it is: /system/juma/inc/bluenrg_sdk_api.h
   For sensors, it is: /system/juma/inc/juma_sensor.h

3. Make your own application
   Modify the seed project, change the logics, flows, algorithms, etc.
   Make it fit to your own application.

4. Compile firmware
   Cannon board has two versions, select the right one in Keil compile option.

5. Download firmware
   Connect Cannon to computer via J-Link or ST-LINK.
   Keil can download firmware to Cannon.

6. Work with BLE APP
   To facilitate BLE development, we offered a BLE debugger APP in /tool folder.
   It can be run on Android mobile to transmit BLE raw data to/from Cannon.
