Get the first (and only) sensor ID: sensor_id = ds.scan()[0] Every time you need a reading: Request a temperature reading: ds.convert_temp() Wait for results to come back: sleep_ms(750) Get the reading back as a floating-point value in °C: ds.read_temp(sensor_id) That’s ...

It is. As Dave says it does a collection then tries to allocate again, then it'll fail if it can't get enough contiguous memory. for some reason is unable to free 582 bytes of contiguous memory? Probably there's just not 582 bytes (37 blocks) of contiguos heap. I would run a gc...
The values obtained from pairs of registers are converted to a single 16-bit value and 2’s complement to get the final raw acceleration values. These values are multiplied by a factor of 3.9, corresponding to a resolution of +/-4g, to obtain acceleration values in mg. The code The ...
Another thing we don’t like about this IDE is that most of the time you can’t get a connection with the board on the first try to upload files. You need to reset the board manually, open the REPL, press CTRL+C, close the REPL and open the Files menu. You may need to repeat ...
MicroPython brings to the microcontrollers a lot of what people were using a Raspberry Pi for in projects anyway: a friendly interactive programming environment that was free of the compile-here, flash-there debug cycle. If you’re happy coding Python on a single-board Linux computer, you’ll...
