I found no documentation for the network.LAN class.
From which micropython version was it implemented in the firmware?
Is there any documentation on how to use it?

Re: compile vs freeze module (with esp32 spiram support enabled)
thank you for your answers.
So regarding question 1. I interpret that there is no big difference in terms of performance between just compiling modules with mpy-cross and freezing them into the firmware.

compile vs freeze module (with esp32 spiram support enabled)
I've always used the already compiled micropython firmware for esp32 with spiram support. I investigated the possibility of improving the performance of the microcontroller (ESP32 WROVER) by compiling modules with mpy-cross and/or including (?freezing?) them into the whole micropython firmware. 1. w...

logging to a log file with limited size
I'd like to log to a file appending new lines and when a maximum size is reached removing older lines in favor of new ones such that the log file does not occupy too much memory. I know this is possibile in python (https://stackoverflow.com/questions/24505145/how-to-limit-log-file-size-in-python). I...

Re: Get full stack trace in try: catch:
the traceback module does not work because sys.exc_info is not available [link](https://github.com/micropython/micropython/issues/5110)

I decided to put the final library on github at this [link](https://github.com/AlekseyFedorovich/ADXL345_spi)

Re: fast (>1kHz) readings from accelerometers
Finally, thanks to SPI protocol, FIFO, and DATA_READY bit I reached 3.2 kHz.
I decided to put the final result on github at this [link](https://github.com/AlekseyFedorovich/ADXL345_spi).

Re: ESP32 ADXL345 (accelerometer) SPI
The key is the SPI diagram in the datasheet (figure 37, figure 38). It's necessary to read at least 2 bytes and the first must be ignored. def read(regaddr, nbytes): wbuf = regaddr | READ_MASK if nbytes > 1: wbuf = wbuf | MULTIBYTE_MASK CS.value(0) value = spi.read(nbytes + 1, wbuf)[1:] CS.value(1) ...
