Re: Strange GPIO behaviour

So if that part is missing I can't do anything to solve the problem? If the pin is not used for wake-up, no deinit is needed. If you remove esp32.wake_on_ext0(d1) then you cannot wake-up with a pin. It works in my MicroPython port ( Forum ). >>> import machine >>> rtc = machine.RTC() >>> d1 = machi...

Re: Strange GPIO behaviour

If I am wrong someone here will correct me. It is my understanding that the ESP32 has 3 cores (2 main cores and 1 ultra low power core). When you put the ESP32 into deep sleep it turns off the 2 main cores and powers down there RAM to save power consumption. The ULP core continues to run but it has...

Re: Strange GPIO behaviour

GPIO used for wakeup must be deinit after wake up to be used as digital input/output again, something like this: if (rtc_gpio_is_valid_gpio(self->id)) rtc_gpio_deinit(self->id); I think that part is missing in the official MicroPython ESP32 port and that is the reason for the "Strange GPIO behaviou...

Strange GPIO behaviour

Dear Community; I am making a low consumption system with an ESP32. I use deepsleep mode to save power. I need to wake up my ESP32 every x seconds and when a button is pressed. To achieve that I use the following code: import machine import time import esp32 time.sleep(2) d1 = machine.Pin(14, machin...

I'm finishing the usqlite3 module implementation for my MicroPython port, based on this library.
It works great, I expect to commit it next week.
Thank you Loboris;

When you launch it, please post in this topic. Fantastic job :D :D

The ffi module isn't supported on the ESP32 port, only on the unix port.
Thanks for your answer.

Assuming that ffi is not available for ESP32, is there any way to use databases in Micropython? I am really interested.

Thanks.

Re: Post method Micropython.

I get the same error under CPython 3.4.3. Perhaps this might be relevant ? Hi: Thanks for your answer. I asked for help in a Portuguese MicroPyhton speaking Telegram group and we found a solution: import urequests as requests url = "https://io.adafruit.com/api/v2/username/feeds/battery/data.json" h...
