You can update the chipset's firmware(bakebit_firmware.hex) of the NanoHat Hub by following the instructions below:<br />
 +
Install avrdude on NanoPi NEO/AIR's system:
 +
<syntaxhighlight lang="bash">
 +
apt-get install avrdude
 +
</syntaxhighlight>
 +
 
 +
Append the following lines in the "/etc/avrdude.conf" file:
 +
<syntaxhighlight lang="bash">
 +
# Linux GPIO configuration for avrdude.
 +
# Change the lines below to the GPIO pins connected to the AVR.

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.
