Instructions for programming and using functions.

Below you can find a tutorial on how to use all the functions of the device as well as hardware information.

1. Install drivers for the serial programmer and be able to upload code.

-Download the driver for the CH340C serial adapter



These are compatible with: Windows 10/8.1/8/7/VISTA/XP, Server 2016/2012/2008/2003, 2000/ME/98.

Then  the installation will be shown in Windows 10, but it is applicable to all Windows systems that the driver is compatible.

After downloading the file .zip extract all its contents to a new folder on our desktop that we can call "Drivers".

When  finish, we would have to see our folder.

Then  do a search in Windows for: DeviceManager.

Next, connect our LEDBOY to a USB port and search the device manager under "Other Devices"

“USB Serial”

right-click on"USB Serial"  and the following window will appear,  click "Update driver"


Then  choose the option to search for drivers on the computer


Chose the "Browse" option and looked for the "Drivers" folder that we did earlier with the  driverfiles.

Accept and then give the Next option, if everything goeswell,  we will be shown this message and the drivers will already be installed.

Now close all windows and continue installing the IDE to program


2. Preparing to  program the console.

LEDBOY uses the Arduino IDE to program itself

-Download the Arduino IDE: https://www.arduino.cc/en/software

Download the desired version (minimum recommended version 1.8.13).

Next, we will need to make an initial configuration.

-Manager of tarjetas:

Open the downloaded program and a window will open with a blank project. We proceed to select the preferences option in the files tab.

Once the window is opened, enter the following URL:


If we have a URL already entered, it is not necessary to delete it, we simply add the new one below. We give OK to all windows to save the changes.

Then go to Tools-Board-Card Manager.

When the card manager opens we will need to look for mega  TinyCore  and install it to have support for  the  Attiny  1614.

Once this is done, we will have support to program the microcontroller integrated in LEDBOY.

The good thing about the Arduino IDE is that there are many libraries available to execute functions or integrate peripherals in a very simple way, you can install as many as you need since these are installed on the PC but when integrating them into the project you must be careful since these consume resources of the microcontroller and we can easily run out of space. 

3.Create a program, compile it and upload it to the microcontroller

Also applicable for downloaded games or programs.

To create an Arduino program :  first of all integrate the libraries needed for our program this provide us with functions to facilitate the use of hardware,  for that you can copy the following text at the beginning of the sketch without deleting anything.

#include <tinyNeoPixel.h>

#include "characters.h"

#include <avr/sleep.h>

#include <avr/interrupt.h>

#include <avr/eeprom.h>

tinyNeoPixel strip = tinyNeoPixel(NUMLEDS, NEOPIN, NEO_GRB);

Now you are ready to write your programs and make use of all the functions to program your LEDBOY.

Then we have to select certain parameters in the Arduino IDE so that we can upload our program.

In tools, board, Mega Tiny  core we must choose the microcontroller  Attiny  1614.

Before flashing  LEDBOY we must choose the correct COM port,  if we have a single COM port that is the correct one.

If there is more than one and do not know which one corresponds to our console.

Simply unplug the USB cable from our LEDBOY we leave the options, we go back in and see that port is no longerthere, the COM port that is not  when disconnecting the console is the one that corresponds to LEDBOY , always have it selected.

Mainly  be careful NOT to select any option that has"Optiboot"unless we are sure of what we do, in this option it does notgive the possibility to change the behavior ofl PINUPDI that our LEDBOY uses to upload programs,if we choose the wrong option WE WILL NOT BE ABLE TO RE-UPLOAD MORE PROGRAMS.

It can only be reversed with a special 12v programmer.

Before uploading our program we must check that the options shown in the image match those we have selected in ourprogram.

"Qemar  bootloader" is not necessary touseit if the console already has a program installed, this option is only to  configure  logs on the microcontroller, this is done only once.

It is ONLY necessary to do it again in case a program specifies it or we want to change some parameter.

After everything  is selected, press the arrow which will compile  and upload the program to our LEDBOY.

In the red boxed area the progress will be shown and in the console we should already see the program working.

An average flashing only takes 10sec or less.

If we have downloaded a program or game, we will have a folder with the name of the program and within this an .ino file that is the one that we will have to double  click and this will open in the Arduino environment, we can upload it with the method already described above.

It is important to keep all the files inside the folder and not to modify the names.
