Thanks for your reply (and also libs, I use some, eg. MPU9250). Doesn't seem a USB problem - I get the same error with 'connect telnet 192.168.10.104'. Also, pymakr (running on the ubuntu virtual machine) works. I guess I'll need to download the rshell code and figure out what's wrong with the eval ...

Apparently the ESP32 IDF supports mdns: https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/tests/task_mdns.cpp?utf8=✓ Is is possible to call this from Micropython, specifically MicroPython_ESP32_psRAM_LoBo? Am I correct that "all" that's required is a wifi connection, followed by the C-...

Yes, it shows up in ubuntu when the device is plugged in, and disappears when unplugged.

When starting rshell six-1.11.0 on ubuntu with rshell -p /dev/ttyUSB0 I get the following error Connecting to /dev/ttyUSB0 ... Traceback (most recent call last): File "/usr/local/lib/python3.5/dist-packages/rshell/main.py", line 1185, in connect ip_address = socket.gethostbyname(port) socket.gaierro...

logger.py included with loboris' MicroPython does not define the function basicConfig. It is used by a library I am using. For reference I am including the code for a different logger.py downloaded from the web (with basicConfig and a few other differences). What's the best way to get these differe...

Ran into the next problem (with "loboris' MicroPython" - rest works very well): File "ssd1306.py", line 1198, in write_data AttributeError: 'I2C' object has no attribute 'write' dir(i2c) indeed only lists writeto and writeto_mem. scan shows the device ([60]) as expected, and I also can communicate w...

Thanks!

Figured it out. This problem occurs only if the PWM channel on the particular pin has been allocated already. Resetting the board will fix this.

Follow-up question: is there a way to "dis-allocate" a PWM channel, so it can be used again?

I cannot find a working PWM example for ESP32 with Laboris fw (I use a Huzzah32 board). The following code won't blink the led: from machine import Pin, PWM pwm = PWM(Pin(13), freq=1, duty=512) # pwm.duty(512) Also, uncommenting the last statement gives an error: ledc: ledc_set_duty(339): LEDC chann...

It's set in mpconfigboard.h.
