Repository for the robot Firmware code of the UnBall team

This repository is related to the firmware where it can receive communications (via wifi or radio) and it can control the robots.

Attention

If you in linux you seem to not have permission to pass the code into the board, try:

sudo chmod a+rw /dev/ttyACM0
#or 
sudo chmod a+rw /dev/ttyUSB0

the /ttyDeviceN is related to how your OS reads the board and the board drivers N -> is related exclusively to the number of boards/usb devices into your computer :)

Installation

The firmware code can be found at: UnBall - Firmware.

This firmware is uploaded using the platformIO extention for VScode editor. To install the VScode editor download the .deb file from VScode and in the terminal use the following command:

dpkg -i path/to/debFile/debFileName.deb 

Once the VScode editor is installed to install de platformIO extention follow the instrutions at PlatformIO - installation.

if PIO isn't working properly or isn't reading the python3.6.9, try:

sudo apt-get install python3-venv

then reboot VSCODE.

Uploading

IF USING A EXTERNAL POWER SUPLY, USE THE ADAPTED NO POWER USB CABLE

Use the platformIO extention options to build and upload the code.

Debugging

You can use the debug from PlataformIO with VSCode or change the line in main.cpp:

#define WEMOS_DEBUG false

to

#define WEMOS_DEBUG true

Note that to upload the firmware, you have to put WEMOS_DEBUG to false.

Note!!

If you are using Linux:

At platformio.ini the default upload port to the project is

upload_port = /dev/ttyUSB0

But if you disconnect and connect the usb again, the port can be /dev/ttyUSB1. And an error could occur.

Besides that, in your OS the serial port could be /deb/ttyACM0 or /deb/ttyACM1 (if the situation above happens).

If you are using Windows:

We recommend to comment the code line above because Windows handles serial ports in another way.

Caution

If the plataform.io isn't showing any ttyUSB or ttyACM ports on ubuntu it probably is related to BRLTTY modules, then we gonna have to remove it. Don't worry this module is related this module is for acessibility related to braile display onto ubuntu.

To start it you gotta list all the devices, just to check if it's working

ls /dev/ttyUSB* 
#or 
ls /dev/ttyACM*

if the port isn't showing there, the system hasn't loaded the board, then it probably is the module, to remove it:

sudo apt-get remove --auto-remove brltty

Unplug and replug your board, type again in Terminal

ls /dev/ttyUSB* 
#or 
ls /dev/ttyACM*

it probably fixed it for you, but if it hasn't fixed try the link below.
