Re: ssd1306 SPI, static noise display
So, does it show the same snow pattern each time? And I assume that does not move after your program runs? If so, I would guess wrong pins or maybe the baud rate is too fast for some reason. I have only used I2C on these displays which worked with no problems, so these are just guesses but seeing as...

Re: Is MicroPython the right hammer for my nail?
Well, I have to say that building your own version of MicroPython is more challenging, but your students won't have to do that once you have. I couldn't manage it on Windows but I did succeed on a Raspberry Pi and I would have managed that more easily if I had read every little detail of the process...

Hugely different deepsleep current consumption with wake_on_ext0 and ext1
If I use this code with ext1: wu = Pin(34, mode=Pin.IN, pull=Pin.PULL_DOWN) esp32.wake_on_ext1(pins = [wu], level = esp32.WAKEUP_ANY_HIGH) deepsleep() I get 5uA consumption on my ESP32 break-out board If I use this code with ext0: wu = Pin(34, mode=Pin.IN, pull=Pin.PULL_DOWN) esp32.wake_on_ext0(pin ...

Re: Is MicroPython the right hammer for my nail?
I'm a beginner with MicroPython and I've been using it with various generic ESP32 boards (and an ESP32 bare-board setup with a CP2102 to connect to USB) with little problem, using Thonny as my development environment on Windows 10. The only areas I've found tricky are low power scenarios, trying to ...

Re: Having set a pin as a Touch input, how do I turn that OFF?
Ah, OK, yes. Will do. At least I haven't missed something obvious!
Thanks for the pointer to the underlying code.

Having set a pin as a Touch input, how do I turn that OFF?
So, I have a touch pin that works well, but to save power, I want to turn it off, i.e. turn it back to an unassigned pin, or anything really to stop the ESP32 wasting power putting the touch sense signals on that pin. Whatever I do seems to cause the touch pin to trigger and so immediately wake up m...

Re: Why can MicroPython not use the ULP WAKE instruction
@clone There is no disable_ulp_wakeup in official API, because you have to call enable_ulp_wakeup() every time before you go to deep sleep if you want to enable ULP wake. Ah, OK, well, I can live with that; thanks for pointing that out. I should have read more of the Espressif docs before asking dum...

Re: GPIO always high
Maybe it's the way you copied your program, but that looks like an empty While true: loop followed by one go at copying button.state to the LED
