BakeBit - NanoHat Hub Interface
  • Each BakeBit interface is a 2.0mm pitch 4pin connector. Here is its specification:
  • I2C Interface

There three 5V I2C interfaces on the top row. The first pin from the left is SCL and the second pin is SDA.

Pin Name Description
1 SCL SCL
2 SDA SDA
3 5V 5V supply voltage
4 GND Ground
  • Analog Interface

There are three analog interfaces on the second row. The first pin from the left is An and the second pin is An+1. For example A0/A1 stands for the first pin A0 and the second pin A1 from the left. Usually it is abbreviated as A0.

Pin Name Description
1 An Analog An
2 An+1 Analog An+1
3 5V 5V supply voltage
4 GND Ground
  • UART Interface

The NanoHat Hub has two UART interfaces. When you connect the NanoHat Hub to the NanoPi NEO/AIR the first UART on the third row from the left is directly connected to the NEO/AIR's UART1. The second UART is the UART populated from NanoHat Hub's chipset and this UART can be used as D0/D1.

Pin Name Description
1 Rx Receiver
2 Tx Transmitter
3 5V 5V supply voltage
4 GND Ground
  • Digital Interface

The remaining four are digital interfaces. The fist from the left is Dn and the second is Dn+1. For example D2/D3 stands for the first pin D2 and the second pin D3 from the left. Usually it is abbreviated as D2.

Among these 5 digital interfaces D2-D6 D3, D5 and D6 can be used as PWM.

Pin Name Description
1 Dn Digital Interface Dn
2 Dn+1 Digital Interface Dn+1
3 5V 5V supply voltage
4 GND Ground

3 How To

BakeBit - Refer to this link for more details on how to connect the NanoHat Hub to the NanoPi NEO/AIR:BakeBit - How to Connect NanoHat Hub to NanoPi NEO/AIR

4 BakeBit Modules

Here is a list of BakeBit modules that can work with the NanoHat Hub:

5 Update NanoHat Hub's Firmware

You can update the chipset's firmware(bakebit_firmware.hex) of the NanoHat Hub by following the instructions below:
Install avrdude on NanoPi NEO/AIR's system:

apt-get install avrdude

Append the following lines in the "/etc/avrdude.conf" file:

# Linux GPIO configuration for avrdude. 
# Change the lines below to the GPIO pins connected to the AVR. 
programmer 
  id    = "nanopineo"; 
  desc  = "Use the Linux sysfs interface to bitbang GPIO lines"; 
  type  = "linuxgpio"; 
  reset = 67; 
  sck   = 66; 
  mosi  = 64; 
  miso  = 65; 
;

Enter the "Firmware" directory and run the "firmware_update.sh" script to update the firmware:

cd ~/BakeBit/Firmware 
./firmware_update.sh

After a prompt shows up select "y". If the update is done successfully you will see the following messages:
BakeBit-UpdateFirmware.jpg
The firmware is a ".hex" binary file and you can check the latest version by running the "new_fw_search.sh" script.

6 Compile Firmware with Arduino IDE

1) Download the Arduino IDE from the following link and install it on your host PC:
https://www.arduino.cc/en/Main/Software

2) The Arduino IDE's installation directory has a "libraries" directory. Copy the whole "BakeBit/Firmware/Source/FastLED-FastLED3.1" directory to the "libraries" directory. In MacOS the libraries directory is "/Applications/Arduino.app/Contents/Java/libraries/"

3) Open the BakeBit project file in Arduino IDE:
BakeBit/Firmware/Source/bakebit_v1.0.0/bakebit_v1.0.0.ino

4) In the main Arduino GUI open the "Tools" menu and change the Board model to "Arduino Nano":
BakeBit-ArduinoBoardType.jpg
5) In the main Arduino GUI open the "Sketch" menu, select "Export Compiled Binary" to start compilation.

6) If the compilation succeeds a binary file "bakebit_v1.0.0.ino.eightanaloginputs.hex" will be generated. Rename the file to "bakebit_firmware.hex", upload it to "NanoPi NEO" and replace the file with the same name under the "BakeBit/Firmware/" directory. Follow the instructions in the previous section to run the firmware_update.sh script to flash the firmware.
