Not only that but the OLD password system has been upgraded to use certificates and encryption keys.

Currently my solution is that I wrote software that tunnels data between a virtual serial port and a real one, while displaying it to me. It uses com0com to setup the fake serial port.

Basically, m5stick is COM4, com0com is configured with fake COM6 and COM7. COM6 is connected to COM4 via my app and I can see the text in between them and inject keystroke too. VSCode talks with COM7 and all of the data from COM7 goes to COM6, to my screen, then to COM4

I also coded it so if I hit ESC, it sends the CTRL-C signal to the terminal so it brings up REPL. (pressing CTRL-C will quit the whole terminal lol)

This solution still sucks, exceptions are still printed to the LCD instead of to the COM port

wlan = network.WLAN(network.STA_IF) is 0_1654418854491_a0cdea9b-ae52-4361-82e6-68b7f114500a-image.png

i didnt used create station interface because of that wlan wasnt defined!

Thanks Felix

Check out UIFlow: How to try/except for "Connect to Wifi"?

Thanks for the response Flypeek, I've seen both those and nothing works. The M5Stack just reboots.

Found my error. I had flashed the M5 with a program of my own using Arduino. Using the UI Flow firmware, I get the Micropython REPL no problem with screen /dev/ttyUSB0 115200.

You cannot read data from this microphone via analog read. This microphone is digital and has two digital pins. One of them is clock signal (probably connected to gpio0) which you should drive with 1MHz signal. Second is digital output which give a signal similiar to pwm signal (pulse density modulation) . So only walues which you read are 0V or 3.3V.

Results seem to be very inconsistent between different versions of MicroPython. Running the exact same code in some it works as expected and in others the results are wrong (full results below)

My guess is either the code to set attenuation is not working correctly in some versions, or there is some other factor to do with the ADC that is set differently by default on some versions.

yes, I have a partial record but have been constantly bugging M5Stack for the API's.

You can find the API's in my WIP book located here:

Hello @ankit17340

ok, good. One more thing, do you manually put your STAMP into download mode by holding the 'boot' button and pressing 'reset' on your USB UART download setup? If so try the same before clicking the 'Configuration' button in M5Burner.

Explanation: changing the configuration uses the same mechanism as burning firmware, just for a tiny part of the flash only holding the settings.

Thanks
Felix

The firmware is updated monthly but because of Chinese New Year things have been quite. A new firmware is coming out based on Micropython 1.7 but only a test version is available. As to pycharm, never heard of it.

So I loose the error but have no sign that its connecting, I have a monitor running is VSCode but it show no sign of the core connecting.

Yes, watchdog timer could be an idea. The same can be done with a normal timer and calling machine.reset() when it fires.

However I was wondering if there was a more graceful way of handling this, e.g. interrupting just the hanging urequests.request() method and then continuing with the program without rebooting the whole device.

@mlindholm would you share the link to that blog post?. Thanks.

Thanks a lot. This seems exactly what I was looking for. Command line is not a problem. Will try it.
