Re: 3-Axis tilt sensor for tilt only

Hi, as far as I understand - if I'm mistaken, please excuse me - your question is, if the sensor would be able to determine if it's on an incline, always giving you only the angle of the loader bucket? I don't have hands-on experience with these sensors, but from what I understand of their principle...

Re: interest for tiny usb hid integration?

hi noobee! tested your implementation, it works great so far. I've only got one little question regarding sending key presses: Is it possible to send complete strings with the keyboard? It would make sending data to a commandline or e.g. notepad much easier :D I see that in the keyboard.py there is ...

Re: Powering ESP32-S2 from a single Li-ion cell

Not only maximum cell voltage needs to be taken into account, I'd also consider the lower limits of the cell. If battery efficient operation isn't needed, one could use a TP4056 based charging / protection board (which would also handle charging the cell, but then you'll need a relay / FET to discon...

Re: SoftI2C with two same devices

Hi, I'm using an ESP32 and it's two I2C without a problem. Maybe there's an error in your configuration? Could you post how you instantiate the i2c devices? On the ESP32 DevKit I'd try to use the hardware I2C bus. Here's the official documentation on SoftI2C: https://docs.micropython.org/en/latest/e...

Re: Why my Raspberry Pi does not have audio option in Advanced Options?

That question may be better suited on the raspberry pi specific forums, as this forum focuses on a python port for microcontrollers.
https://www.raspberrypi.org/forums/ would be a forum for all questions raspberry pi.

best regards :)

ESP32 (Pulse) Counter capability

Hello everyone, I'm trying to DIY a wind sensor using a LM393 IR bridge sensor module. For that, I would like to read the pulses generated by the sensor with an ESP32. The ESP32 should perform other measurements, too. I'm trying to work with Pin.irq but having some (understanding) problems*. First q...

Re: VL53L1X ToF distance sensor - adapting to micropython

Hello everyone, I know this is quite old, but I'm a bit out of ideas in getting this sensor to work. The library which is linked in this thread is not available anymore, so I'm using https://github.com/uceeatz/VL53L0X Now my problem is that this library is coming from a pycom wipy board, which I do ...

Re: Micropython library for the TI INA219 voltage/current sensor

Thanks again for your help =) I'm in the middle of re-arranging the config register values, after I just figured out the differences. Interestingly, even though the differences are quite significant, it works even with the config register values for the INA219 device. As soon as I have implemented t...
