Data type conversion with adc

[Le fond du garage]

an example for schedule

Code: Select all

import schedule
import time

def job():
    print("I'm working...")

schedule.every(10).minutes.do(job)
schedule.every().hour.do(job)
schedule.every().day.at("10:30").do(job)
schedule.every().monday.do(job)
schedule.every().wednesday.at("13:15").do(job)

while True:
    schedule.run_pending()
    time.sleep(1)

and do bind with irq use this

Code: Select all

def hard_irq(arg):
    micropython.schudule(soft_irq, arg)

I produced a "micro" version of schedule using uasyncio here.

Thank you for your advices.

I found an "off road" solution.

Code: Select all

# main.py -- put your code here!

from pyb import Timer, Pin, ADC, DAC

tim = Timer(1, freq=1000) # Définition du timer 1 à la fréquence 1000Hz

tick = 0
echeance = 1

def correction():
    # ADC conversion
    # Control equations
    # DAC conversion
    
def gestion_echantillon(timer):
    global tick
    tick += 1
    
# Fonction qui se déclenche à chaque fois que le timer finit sa boucle
tim.callback(gestion_echantillon)

while True:
    
    if tick == echeance:
        echeance +=1
        correction()
        
    	if tick == 2**24: # Set to init position
        	echeance = 1
       		tick = 0

This method works experimentally. Between two output, I measured 1ms (+- few micro-seconds).

I think it is not the best micropythonic way of coding but it works for me.
