Downloading MicroPython Scripts.

... utility that generates some MicroPython code and downloads the same to a device running RPI Pico. Currently the utility needs AMPY a utility from Adafruit to download the MicroPython script and run it on the RPI device. This also means the user has to download and install python to make all this ...

Re: Pico and BNO055 IMU

I have raised this issue . I encountered some invalid data running at 400KHz. A scope revealed waveforms with slow risetimes, a consequence of the Adafruit board's 10KΩ pullups. Adding 1KΩ pullups fixed the waveforms. The test script now runs reliably for long periods. Perhaps the Pico pins have ...

Re: Pico and BNO055 IMU

... get hard I2C to work and soft I2C only works reliably at 4Kbaud. Electrical conditions are identical in all my tests: leads are short and the Adafruit breakout board has pullups. It does seem that there's a bug in the MicroPython's implementation of I2C on the RP2. I'll do some more testing ...

Re: Pico and BNO055 IMU

... measured it). We're talking about a PiPico, your library and micropython. It cannot be due to my hardware, because: The whole thing works with Adafruit BNO055 Library and CircuitPython at 400KHz without any problems on my hardware! I think MicroPython together with the PiPico make a mistake, ...

Microsecond decoding board recommendation

... a Manchester coded sequence (no clock) running at 100 uSec. I need to detect a falling edge then read the pin state at 12 uSec and 75 uSec I tried Adafruit’s CircuitPython and determined that the timing resolution is in the single digit mSec range. Is there a MicroPython board that can read pin ...

Re: Can't install adafruit-micropython-blinka

It may help if you create a Python virtual environment.
That way less chance of insufficient privileges.

You could try my script https://github.com/pappavis/thescript/b ... tualenv.sh which should work fine on MacOS too.

Can't get REPL after loading micropython on ESP32-S2 Feather

Greetings - I've tried several times to flash micropython on to my ESP32-S2 Feather. I've used * Adafruit web espytool * Command line espytool * Thonny install/update firmware tool all with the same results and per the instructions. After flashing the firmware, hit reset, ...

Re: Pico and BNO055 IMU

Done that and still getting the error. I've tried using Micropython and it seems to have fixed that problem, however it now says: "RuntimeError: No BNO055 chip detected."

I have the Adafruit BNO055 plugged in using GPIO 0 and GPIO 1. Do I need to activate SCL and SDA somehow?
