[mod] Beduino Controller [beduino]

Beduino

A microcontroller for Minetest



Beduino is a 16-bit microcontroller and development environment with editor, file system, compiler, assembler, and debugger, based on the mod vm16. The controller can be programmed in mC, a C like language.

Beside vm16, the mod has no dependencies. However, it comes with an I/O module for techpack and techage.

Support for other technology related games or mods is possible.

Browse on GitHub or download the code.

Dependencies: vm16, optional: techage, tubelib

Beduino is fully integrated into the Mod Techage and can be used as an alternative to the Lua controller.

Further information about Beduino, the programming language and the techage commands can be found in the wiki

The video shows the use of the Beduino controller as lift/elevator controller for techage.

The code for this demo:

Code: Select all

import "sys/stdlib.asm"
import "lib/seg14.c"

func init() {
}

func loop() {
  seg14_putstr(0, "TO BE OR NOT TO BEDUINO ");
  sleep(20);
  seg14_putstr(0, "  THAT IS THE QUESTION  ");
  sleep(20);
}

Hi,

I wondered if to find a MT mod NPC for the desert biomes like a Bedouin but found this...

To be or not to Be-duino: That is the question!

Hilarious.

Have fun.

[joe7575]

LOL, no Beduino is a microcontroller mod and has nothing to do with desserts.

The name is a nod to Arduino controllers

[joe7575]

Beduino has reached V1 with many updates and improvements

One example is the IOT sensor.
An IOT sensor that can be programmed like the Beduino controller to monitor and control nodes in its environment

Here it controls a color lamp when a player is nearby (the player detector is in active state):


Example program in mC:

Code: Select all

import "lib/techage.c"

const STATE = 142; // player detector state
const COLOR = 22;  // color lamp command
var OFF = "\377";
static var data;

func init() {
  send_cmnd(1, COLOR, OFF); // Turn color lamp off
}

func loop() {
  var resp;
  var sts;

  sts = request_data(2, STATE, 0, &resp);
  if((sts == 0) and (resp == 1)) {
    // Turn color lamp on
    send_cmnd(1, COLOR, &data);
    data = (data + 1) % 256;
  } else {
    send_cmnd(1, COLOR, OFF);
  }
  sleep(2);
}

Hello, we are faced with the fact that when using any Slavic language, ru, ua, instead of letters - dots. Is it possible to fix it somehow? Thank you.

[joe7575]

Currently it doesn't work. VM16/Beduino only work with ASCII characters. But I can imagine a display that understands Unicode characters. In the controller, you would then have to define the strings with control characters so that they are output correctly on the display

We have a technical server, and we want to make an in-game email for exchanging messages between players. Almost all of our players speak only Russian, Belarusian and Ukrainian. Almost no one knows English to correspond freely in it. We will be very grateful to you for any help.

[joe7575]

I will try it soon...

It is already working.
Try this example together with the termlib terminal:

Code: Select all

import "sys/stdio.asm"
import "sys/os.c"

func init() {
  setstdout(2);  // Use external terminal for stdout
  putstr("\b");  // Clear screen
  putstr("+----------------------------------------------------------+\n");
  putstr("|                Termlib Demo ÄÖÜäöüaßß                    |\n");
  putstr("+----------------------------------------------------------+\n");
}

func loop() {
  var c;

  c = getchar();
  if(c > 0) {
    while(c > 0) {
      putchar(c);
      c = getchar();
    }
    putchar('\n');
  }
}

I have a German keyboard and I have tested it with some German umlauts (ÄÖÜ).
It works as expected:

Hello dear joe7575.

Your terminal is working fine!
There are no limits to our gratitude!
But is it possible to use formspec in the terminal to create a user interaction interface? And how to use formspec on Touchscreen on beduino in general? In Touchscreen, it was possible to display only text, as on a regular monitor. But feedback is needed. I couldn't find any examples of a program for this. Maybe I was looking badly? But if you don't have a description of how to do this with sample programs yet, we'll be looking forward to you writing it.
Tech Age is the main and main mod on our server. Everything else adapts to it. As the owner of the server, I am immensely glad that the developer of our main mod himself personally made a very necessary addition to us. I am sure termlib will be in demand on all servers using TechAge.

With great gratitude and respect, main spirit.

There is a touchscreen mod available for techage: https://github.com/Thomas--S/ta4_addons
Unfortunately, it does not support Beduino, but you can ask the author to add Beduino support.
