I2S: Stereo input/output

Hi, I have two INMP441 i2s mems microphones, which each are mono microphones but can be set to represent either the left or the right channel. Further I have two MAX98357A I2S amplifiers, again each is a monofonic (monophonic?) amplifier but can be set two represent either the left or the right chan...

How to exec py-file as a main.py replacement?

Hi, I simply don't know how to create a search string for this possibly super simple question... I want to create a main.py which consists of several expressions, which directly execute other *.py files (named in the main.py) in sequence with the same effect, as if their code would be included in th...

How to "device driver"

Hi, I am using an ESP32(WROVER-B) based board by TTGO and Linux is my OS. :) To use an ILI9340 driven TFT display with this board I need a device driver....and crawling the forum I found one (https://forum.micropython.org/viewtopic.php?f=14&t=1996&hilit=ILI9340#p11180). But that one is located in th...

Re: To update or not to update µpython ?

Hi,

ah...ok...

I did a "git checkout esp32-idf41-cmake; git log" (I am on linux) and got the same log as before: Newest change is 29.10.
How can I read of the latest changes of this specific branch?
Thanks a lot for any help in advance!
Cheers!

To update or not to update µpython ?

Hi, I am unsure, when to update the mycropython on my board: Usually I tend more to the unstable/"bleeding edge" kind of software (in general) then to the other end, where is as stable as old (exaggerating a lot here.. ;) I have a clone of the mycropython repo (github) on my harddisk. Last change ac...

Re: Save/Restore pin configuration of a certain pin

Hi, ...about promiscuous mode again. What I found in the forum so far are threads, which end all somehow unanswered. I found one thread offering patched images of µPython (but I didn't find the according source...), which should work that way. But they did not work for me...my board simply crashes. ...

Re: Avoid writing to the flash for the simplest corrections?

Hi, thanks a lot for the information -- it helps me a very much! Everytime I handle flash in one or the other way a creepy fear crawls up my spine whispering " BE CAREFUL ! IT'S DEADLY! YOU HAVE BEEN WARNED!" :) I know, it is not <cough> scientifically based <cough>...but it still exists. The CTRL-E...

Avoid writing to the flash for the simplest corrections?

Hi, when it comes to (Micro-)Python I am a very beginner. Or in other words: I am learning from my mistakes. From my Linux PC I connect to my ESP32 board via rshell or Thonny. When loading (for example) /pyboard/main.py into an editor (rshell) or into the editor of Thonny and run that script, it wil...

Re: (ADC) Unclear: Attenuation changes the physical or the digital range of the ADC?

Hi Robert, (you again! :) Thank you! :) ) I repeat here only for makeing sure I understood correctly -- I don't to fry my ESP32... :) The value of the attenuator limits the maximal allowed voltage at the ADC pin. Is it correct, to imagine the attenuator like a tuneable voltage divider right in front...
