WebApr 4, 2024 · This seems consistent with the fact that Short datatype takes 2 bytes per member. Overhead is quite large, though, especially in MicroPython. Same with Bytes instead: list5 = array.array('B', (0 for _ in range(1000))) - 1062 bytes in Python, 1440 bytes in MicroPython. It seems that overhead is still larger in MicroPython than it is in Python.

Once you can successfully build and flash a firmware build, freezing bytecode is done by putting your Python source in ports/esp8266/modules/, building and flashing. Issuing. Web3. Use ubinascii.hexlify and jump through hoops. ubinascii.hexlify () returns bytes. By decoding the bytes to a str and then converting that str to an int (with base16), we can then pass the value to hex (). There is no hex attribute for bytes in micropython. The below has been fully tested on the Raspberry Pi Pico running micropython 1.14. cleaning jobs altrincham
