But you can use pyboard.py to copy files after you used esptool.py to install MicroPython. Works fine in a script if you put a sleep 5 or something between them to let MicroPython boot.

Someone had a similar problem here related to their WiFi environment – worth a try if the usual measures don’t help.

>robert@mountain-cabin:~/micropython-1.14/tools$ pyboard.py /dev/ttyACM0 blinkpico.py bash: pyboard.py: command not found Naming a command without a path does not search in the current directory, only in the $PATH environment variable. To run an executable from the current directory, say ./pyboard....

Did you erase the flash before installing MicroPython ( esptool.py erase_flash )? The ESP8266 remembers in flash whether WiFi was on and what network it was connected to, and tries to restore that at boot. Maybe it has stale information there. On the first boot after erasing the flash (when no files...

This doesn’t work for several reasons. Lines are in the wrong order (variable is used before assignment). It gives you values outside of the requested range (try with min = 0, max = 0x1fffffff, getrandbits(30) = 0x3fffffff). It doesn’t give you a uniform distribution, some values are more likely tha...

I think you now need to get the toolchain from https://developer.arm.com/tools-and-sof ... /downloads , but I’m not sure (have never built for STM32 myself), and I don’t know which version is best.

As far as I recall, random.getrandbits() is the only function available on ESP8266 (check help(random)). You can build anything else you need on top of that. Here’s a ready-to-use example.

Reword your requirement a little and you have the answer: “don't continue until the button is released” = “while the button is pressed, don’t continue” = while button_up.value() == 1: utime.sleep(.01) Substitute that for your original utime.sleep(.01) . Blocking the program while the button is press...

WebREPL allows file transfer using either the HTML or command-line client.

To check whether the problem is with WebREPL, try a serial connection at the same time, you should see the same thing in both (what you type in one also appears in the other). If the serial connection is stuck too, the problem is not with WebREPL. The behavior you describe is expected if there is a ...
