Whenever I enter the mpython repl using Putty, I am able to read from it, but unable to enter commands. If I use an esp32 everything works fine, but the problem occurs when using the esp8266. I flashed the latest 1.17 mp firmware on a esp8266 board, and also tried older firmwares (v1.13), but the pr...

Hello everyone, Whenever I try running a timer that takes as callback a function containg blocking code in it, the whole repl freezes and does not let me enter any word. Ex.: from machine import Timer def handler(timer): time.sleep(1) print('hello') x = Timer(0) x.init(period=1000, mode=1, callback=...

That's very interesting, thank for your help!
I would also like to ask another question about timers, should I add it here or crate a new thread? Sorry I'm not very familiar with forums

Yes the function only takes the self parameter, I totally forgot to add one for the timer instance.

Code: Select all

  def mymethod(self, timer):
      print('hello')

This solves it, thank you. But what if I want to pass other parameters?

Hello there, I am trying to use an object's method as a timer callback: #creating a new object a >>> a = test() >>> a.mymethod <bound_method> >>> timer = Timer(0) >>> timer.init(period=50, mode=1, callback=a.mymethod) At this point, each time the timer runs it gives me this error: TypeError: functio...

Hello (again)! I am trying to make an esp8266 talk to an esp32 using a softAP (no internet available). I am using the esp32 as the AP to wich the esp8266 connects to, and I am trying to use sockets to enstablish a fast comunication. I can successfully connect the esp8266 to the esp32 AP using those ...

Edit: ulab does support matrix multiply -- https://micropython-ulab.readthedocs.io ... b.html#dot it just doesn't support the @ operator.

Oh How did i miss that Thank you!

Are you saying you noticed no performance difference moving from the matrix maths being implemented in Python to moving to ulab's implementation? That's surprising!! Would be interested to see measurements, but I guess that suggests that your time is entirely being spent somewhere else. I am 100% d...

First of all I would like to thank you all for the super fast support that I received. :D - if you stick with ESP32 : * oficial MicroPython uses as default clock at 160 MHz, so change to 240 MHz -> speed increases about 50%; * use ESP32 board without PSRAM, or a MicroPython firmware without PSRAM su...

Hello everybody! :) I've discovered micropython a few weeks ago and I am just loving it! I've recently been working on a hexapod robot and I am currently controlling it with a rasberry pi. Since the code is writted in python and I want the robot to be wirelessly controlled, I thought that a esp32 ru...
