Re: Can't get the servo SG90 working

Thank you all, that was the problem indeed. As I said, first time with servos.
I'm now using the great servo D1 mini shield from Deshipu... I'm now looking for a simple idea that can make use of a bunch of servos! ;)

Can't get the servo SG90 working

Hi all, I dismantled a (working) SG90 servo from an old Arduino project and I tried to test it with Micropython. With the code provided in the website I was not able to make it work. Once I write these lines: from machine import Pin, PWM servo = PWM(Pin(14), freq=50, duty=77) servo.duty(30) servo.du...

Re: MQTT and Timers exceptions

Would be nice if MQTT library included a timeout value. I do monkey patching: This code implements a 5 seconds timeout. Somebody should do a pull request for micropython-lib... Thank you for your answer. However, it may seems dumb to you as I'm just a beginner, but I thought that the problem was th...

MQTT and Timers exceptions

Hello, I was toying with mqtt and I got stuck when I introduced a timer to call the mqtt connection. This is what happens: if I call the mqtt object connect() method while the broker server is offline, I get an OSError exception. So far so good. However, I need my mcu to send a data report every fix...

Re: RuntimeError: maximum recursion depth exceeded

What I said above makes any sense to you? It does. During my work on the ftp server I oberved that concurrent system calls, especially on the filesystem, brings trouble. You situation is similar. The firmware does not seem to be reentrant. The is a compiler switch in the FAT module, but as far as I...

Re: RuntimeError: maximum recursion depth exceeded

I'd still be wary of file reads in an ISR. Rather than storing multiple files, have you considered storing a python object such as a dict or list in a single file using pickle or ujson? That way you can read the file once at the start and close it, accessing the various elements as required. This i...

Re: RuntimeError: maximum recursion depth exceeded

just another thing: do you know why the filesystem gets corrupted so easily if there are a lot of file in the root? last time it worked for 15 minutes... I think i found the reason why the filesystem was getting corrupted so easily. I have a couple of function that write on the filesystem, and I fo...

Re: RuntimeError: maximum recursion depth exceeded

I would probably avoid using a timer and just run a loop which achieves its timing like this: import utime while True: tstart = utime.ticks_ms() # do all your stuff delta = 150 - utime.ticks_diff(utime.ticks_ms(), tstart) if delta > 0: utime.sleep_ms(delta) Note I haven't actually tested this ;) Ma...

Re: RuntimeError: maximum recursion depth exceeded

You'll find flashbdev.py in the source tree esp826/modules. It would seem to be the low level driver for the flash memory - my guess is that the readblocks method is being called recursively perhaps owing to re-entrant code. When you change parameters is there a situation where a timer callback exe...

RuntimeError: maximum recursion depth exceeded

Hello everyone, I keep having this error while I'm not using a recursive function (meaning that is not using recursion a function that I wrote myself, mybe I'm using some fuction that is recursive and I don't know). What my program does is as follow: every 150ms a timer calls a function. Everytime t...
