==Communication==
 
BPI-NANO has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega168 and ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1).

Rather then requiring a physical press of the reset button before an upload, the Arduino Nano is designed in a way that allows it to be reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the FT232RL is connected to the reset line of the ATmega168 or ATmega328 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip. The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload.
  
当计算机发出DTR信号时(低电平),复位端将得到一个足够长的脉冲信号,从而复位ATmega328。在Arduino IDE中点击上传程序,在上传前即会触发复位,从而运行引导程序,完成程序上传。
+
This setup has other implications. When the Nano is connected to either a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB). For the following half-second or so, the bootloader is running on the Nano. While it is programmed to ignore malformed data (i.e. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board after a connection is opened. If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.

There is a self-restoring fuse on the bpi-uno that automatically disconnects the power supply when short-circuiting or overcurrent exceeds 500mA, thus protecting the USB port and bpi-uno of the computer. While most computer USB ports provide internal protection, this fuse provides additional protection.

Power

BPI-NANO can power with MicroUSB port,PH2.0 port and VIN port.

Power dependent pins are as follows:

  • PH2.0 port: can input 7-12V,It can be controlled by a power switch。
  • 5V:5V power PIN。when use USB power,direct output USB supplied 5V voltage;When using external power supply, output 5V voltage after voltage stabilization压。
  • 3V3:3.3V power output PIN。output Max is 50 mA。
  • VIN:Connect to external dc 5V power supply
  • REF:I/O reference voltage. Other devices can identify the development board I/O reference voltage through this pin。

Note:FT232RL will only work if it is powered through the USB port。

Input and Output

Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions: Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip. External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.

Some of them have special functions and these pins are as follows:

  • Serial:0(RX)、1(TX),Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip。
  • xternal Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value
  • PWM output:BPI-NANO have 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.
  • SPI:10(SS)、11(MOSI)、12(MISO)、13(SCK),These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language。
  • L13:There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.。
  • I2C: 4 (SDA) and 5 (SCL). Support I2C (TWI) communication using the Wire library (documentation on the Wiring website).

BPI-NANO have 6 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. Additionally, some pins have specialized functionality:

There are a couple of other pins on the board:

  • REF:Reference voltage for the analog inputs. Used with analogReference().
  • Rst:Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board.

LED

BPI-NANO have 4 LED,The effects are as follows:

  • ON:Power indicator.When the bpi-nano is powered ON, the ON light comes ON
  • TX:Serial transmission indicator. When connected to a computer using USB and the bpi-nano transmits data to the computer, the TX lights up
  • RX:Serial receiving indicator. The RX lights up when the USB is connected to the computer and the bpi-nano receives data from the computer.
  • L13:Programmable control indicator. The LED is connected to pin 13 of the bpi-nano through a special circuit. When pin 13 is in a high level or high resistance state, the LED will be lit up. When the electricity is low, it will not be lit up. The LED can be turned on and off by program or external input signal.

Communication

BPI-NANO has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega168 and ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1).

A SoftwareSerial library allows for serial communication on any of the Nano's digital pins.

The ATmega168 and ATmega328 also support I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus; see the documentation for details. To use the SPI communication, please see the ATmega168 or ATmega328 datasheet.

Automatic (Software) Reset

Rather then requiring a physical press of the reset button before an upload, the Arduino Nano is designed in a way that allows it to be reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the FT232RL is connected to the reset line of the ATmega168 or ATmega328 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip. The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload.

This setup has other implications. When the Nano is connected to either a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB). For the following half-second or so, the bootloader is running on the Nano. While it is programmed to ignore malformed data (i.e. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board after a connection is opened. If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.

Arduino Software

Arduino IDE

You can program the PI-NANO through Arduino IDE。

On the BPI-Nano using ATmega328 chip, there is a bootloader program stored, allowing users to upload the program to the development board, without the need for additional programmers. The process of uploading the program was completed using the STK500 protocol.

You can also upload the program to bpi-uno via the ICSP interface without using bootloader

Arduino driver install

  • 1,Windows10 :Windows10 Plug in BPI-Nano and the driver will be installed automatically
  • 2,Windows7 :

After plugging in bpi-uno, the system will try to install the driver automatically. If the installation fails, it will display, "failed to install the driver device successfully". In this case, the driver can be installed manually: Right click on "my computer", device manager, other devices; Right click on "unknown device" and click "update driver software" :
