OK, so the question is whether anyone has written a MicroPython driver for the GC9A01 display. There isn't one, but there is for CircuitPython. Tod Kurt (@todbot) suggested it's very similar to other displays, except it has a custom init code: https://github.com/tylercrumpton/CircuitPython_GC9A01/b...

The Pico doesn't expose a drive like CircuitPython does. Use Thonny or rshell to access the filesystem

can you tell us, please: what board you have: there are lots of NodeMCU variants, all slightly different. how much flash is on board. There's a script in the Arduino ESP8266 package which will work that out for you and display it in the terminal. what esptool.py command line you used, exactly: pleas...

When I try that on MicroPython on Linux, config.json ends up containing: Can you save classes in ujson objects?

What do you mean they are noisy? potentiometer_noise.png That graph is a series of readings from a potentiometer sitting at its centre position, scaled to the same 0 … 1023 range that you are using. It's reading between 509 and 517, but the device isn't moving at all. It's just something analogue d...

So, an analogue (potentiometer) joystick with the y-axis on pin0 and the x-axis on pin1? If I understand the micro:bit's MicroBitPin class right, you're going to get a full range of 0 – 1023 from a read_analog() call. Will you be using this one joystick, or are you writing code that could be used wi...

I think the off-by-one in the day of the week field might be something to do with traditional RTCs being developed before Posix standards became universal in computers. Almost every RTC I've used has been modelled after the MC146818 from 1984: all BCD fields and two-digit years.

but it's always going to be a bit of a hack, since full Unix tz support requires more memory than we'll ever have available. Non-wifi MicroPython boards can get their RTC set from rshell and the host computer's time. The RTC might drift a bit, but it's usually good enough for data logging work. NTP ...

Thanks! Note that binutils-arm-none-eabif should be binutils-arm-none-eabi . I've got a Trinket lurking about somewhere, as well as a Xiao. Update : … success! ish … MicroPython v1.14-132-gd87f42b0e on 2021-04-04; Trinket M0 with SAMD21E18A >>> import machine >>> machine. __name__ bootloader freq me...

robert@mountain-cabin:~$ rshell -p /dev/ttyACM0 -f blinkpico.py That's attempting to execute MicroPython code on your local computer as rshell commands. Not really gonna work so well. One more question, How do I actually just upload the file straight into memory and execute? If you want something t...
