DualMCU v0.0.4

The Pin Remapping Library dualmcu v0.0.4 for the DualMCU ONE board ensures compatibility with Arduino shields when using MicroPython. This version includes a driver compatible with SSD1306 OLED displays.

Installation

1. Open Thonny.
2. Go to Tools -> Manage Packages.
3. Enter dualmcu in the search bar and click Install.

Example of use

1. Connect Multi-purpose Shield to DualMCU ONE
2. Open Thonny and connect to the DualMCU ONE board.
3. Run the following code:

from machine import Pin, PWM
from dualmcu import D5
import time

# Configuración del pin D5 para PWM
buzzer = PWM(Pin(D5))

def play_tone(frequency, duration):
    buzzer.freq(frequency)
    buzzer.duty_u16(32768)  # Configura el duty cycle al 50%
    time.sleep(duration)
    buzzer.duty_u16(0)  # Apaga el buzzer

try:
    while True:
        # Toca una secuencia de tonos
        play_tone(262, 0.5)  # Do
        time.sleep(0.1)
        play_tone(294, 0.5)  # Re
        time.sleep(0.1)
        play_tone(330, 0.5)  # Mi
        time.sleep(0.1)
        play_tone(349, 0.5)  # Fa
        time.sleep(0.1)
        play_tone(392, 0.5)  # Sol
        time.sleep(0.1)
        play_tone(440, 0.5)  # La
        time.sleep(0.1)
        play_tone(494, 0.5)  # Si
        time.sleep(0.1)
        play_tone(523, 0.5)  # Do
        time.sleep(0.1)
except KeyboardInterrupt:
    # Detener el buzzer cuando se interrumpe el programa
    buzzer.deinit()

4. You should hear a sequence of tones.

Ejemplo de uso con la clase Shield

from pins_lib import D5, D9, D10, D11, Shield

# Crear una instancia de Shield
my_shield = Shield(pin_red=D9, pin_green=D10, pin_blue=D11, pin_buzzer=D5)

try:
    while True:
        # Toca una secuencia de tonos y cambia los colores del LED
        my_shield.set_led('red')
        my_shield.play_tone(262, 0.5)  # Do
        time.sleep(0.1)

        my_shield.set_led('green')
        my_shield.play_tone(294, 0.5)  # Re
        time.sleep(0.1)

        my_shield.set_led('blue')
        my_shield.play_tone(330, 0.5)  # Mi
        time.sleep(0.1)

        my_shield.set_led('yellow')
        my_shield.play_tone(349, 0.5)  # Fa
        time.sleep(0.1)

        my_shield.set_led('cyan')
        my_shield.play_tone(392, 0.5)  # Sol
        time.sleep(0.1)

        my_shield.set_led('magenta')
        my_shield.play_tone(440, 0.5)  # La
        time.sleep(0.1)

        my_shield.set_led('white')
        my_shield.play_tone(494, 0.5)  # Si
        time.sleep(0.1)

        my_shield.set_led('off')
        my_shield.play_tone(523, 0.5)  # Do
        time.sleep(0.1)
except KeyboardInterrupt:
    # Detener el shield cuando se interrumpe el programa
    my_shield.deinit()
