Re: Forget a Wifi Network and Ethernet

How can I solve the read only problem? You probably can't. I am not aware of a proven working solution ever being published in these forums. The best way forward is to write a fresh version of Raspbian to a new micro SD card, then with an external usb card reader dongle extract any irreplaceable co...

Re: Forget a Wifi Network and Ethernet

Every single time I reboot the file /etc/wpa_supplicant/wpa_supplicant.conf is changed and overwritten with the old wifi configuration. This might be a symptom of a wider problem with your system. Check that your microSD card has not spontaneously entered a read-only state. Create a trivial file, w...

WiFi.

It's built in to an RPi 3b.

If it isn't built in to the laptop, use a usb WiFi dongle.

Re: Use case list and how-to guide

The pi is a complex piece of hardware. Each pi is somewhat unique. Each RPi is, for practical purposes, unique by virtue of its hardware encoded serial number. But that's all. Apart from that every RPi (of a given model number or type) is exactly the same as every other similar RPi that comes off t...

re-scaling a sprite should not be “alchemy” when it’s su[p]per simple to rotate an Actor (sprite)! As already suggested, give that feedback to the developer/maintainer. You can report bugs, or request features that you think should be in Pygame Zero, using the Github issue tracker. https://github.c...

Re: need help on simple script

All linux-based Operating Systems such as Raspbian have a very robust and very well tested task scheduler called cron.

Setting up a cron task to call your speed test utility at the required time intervals will be a cleaner and more reliable solution.

So can you confirm that the first block of code for motor1 is the content of stepper.py, and the second is the content of stepper2.py? Not necessarily the root of the problem, but something odd to consider.. In both modules you have while True: for pin in range(0, 8): xpin = StepPins[pin] if Seq[Ste...
