===BPI NB-Iot Linaro 96Boards Easy Development with Arduino===
 +
Let us see how you can setup the Banana Pi Linaro with your favourite Arduino IDE and Maple
 +
 +
*Step 1: Install the Arduino board for STM32
 +
 +
In order to use your board with the Arduino IDE, the first step is to install the board definition.
 +
Open your Arduino IDE. We tested this on 1.6.10
 +
 +
Go to Tools > Board > Board Manager
 +
 +
Search for 'Maple Mini' as shown below and install the STM32F1xx by stmduino board
 +
 +
[[File:Nb-iot_arduino_1.png]]
 +
 +
When the board is installed, you will be able to see that there are few board definitions that are added as shown below.
 +
 +
[[File:Nb-iot_arduino_2.jpg]]
 +
 +
 +
Out of the newly installed boards, we are interested in the STM32F103R series, which is the tiny powerhouse we have in our Banana Pi. Like any other Arduino board you will also get the samples for the board under File >Examples >A_STM32_Examples
 +
 +
 +
*Step 2: Install Maple bootloader on microcontroller
 +
 +
If you are lucky enough to get your hands on a Banana Pi with Maple bootloader, you can skip this step. Else read on..
 +
 +
In order to flash a firmware to a microcontroller, usually you need a dedicated programmer for this task such as a PiCKit for PIC microcontrollers and AVR ISP for Atmel AVR microcontrollers. However an easier option is to use a bootloader. A bootloader is a small piece of code that runs for few seconds when the microcontroller is started to check for new firmware over Serial or USB and writes the new firmware to the program memory if available. Arduino has many different bootloaders available for AtMega 328, AtMega 2560 chips by Atmel such as Uno, nano, Mega, Diecimilia etc. in their boards. This makes it very convenient to program a microcontroller right from the IDE (such as Arduino) since it does not need a programmer hardware. All this time you have played with your Arduino, you have been using Atmel chips with Arduino bootloaders programmed via the Arduino IDE. A programmer is needed only to flash the bootloader, which needs to be done only once.
 +
 +
The STM32F103 microcontroller we have in our Banana Pi has its own method of firmware update using a special protocol called DFU. Device Firmware Update (DFU) is a standard protocol used to flash firmware updates to devices over USB. Most middle to high end microcontrollers have in built DFU for conducting firmware updates. The STM microcontroller in our Banana Pi has DFU and in built USB which enables it to flash firmware very easily. This is different to how things are done in an Arduino board with a ATMEL microcontroller where a USB-Serial bridge (FTDI232, PL2303 etc.) connects the host PC USB with the microcontroller USART0. This is because the ATMega 328 or ATMega 2560 microcontrollers in standard Arduino Uno, Nano or Mega boards (except the Leonardo) do not have in built USB ports. Therefore once you plug in the Banana Pi to the PC, it should be detected as a DFU device since DFU device drivers usually comes with any modern Windows OS. We will show how it can be done in Ubuntu in a later post.
 +
 +
If what you read above sounded greek, fear not, as there is a easy way out. The maple bootloader enables you to use the STM just like an Arduino.To make an STM work with Arduino IDE with the board that we installed in the previous step, you should write the Maple bootloader to the STM which is a one time thing. You can find a good resource on how to install the Maple bootloader at Leaf Labs
 +
 +
http://docs.leaflabs.com/docs.leaflabs.com/index.html
 +
 +
You will need a STLink programmer for this process. Once the bootloader is flashed to the memory the DFU becomes active after a board reset for a short period for firmware update. If the IDE does not initiate a firmware update, the STM goes on to execute the program code. Now, the board will now be visible as a COM port in your PC just like an Arduino.
 +
 +
 +
*Step 3: Setup Maple drivers on PC
 +
 +
Remember how we said that the board will be recognized as a DFU device by Windows? Most of the time you will need to introduce the drivers to the device in order to be recognized successfully. This is done using a simple tool called 'wdi-simple'. Refer this video
