@shaunix It would be charging if receiving power from USB, not running off the battery, obviously. The simplest method is probably to use the on-board voltage divider and an appropriately configured ADC to measure the battery voltage. The charging voltage is higher than any voltage you may get while running off the battery.

Clicking the items works for me (without pressing enter) when using Safari on ipad.

@goldfishalpha You're right! Sorry for the confusion and good catch (I'll edit my previous post so as not to confuse future readers)

@Verkehrsrot did you manage to get lopy4 work with platformio ? if yes how did you access teh sigfox or lora functions from cpp ? thanks for your hints

@haziqirfan111 Please post links to datasheets of the soil sensor and RS485 converter.

import time time.sleep(2) import pycom pycom.heartbeat(False) print('main MAC1') print('LED test') print (0xffffff) pycom.rgbled(0x0) Try this code. This should run perfectly fine.

@arthurmed So what are the properties of the pulses to receive, and what kind of device is it that you want to connect? Edit: I just tested that: Even if you specify then number of pulses, it will not return until a timeout happens (and the documentation is still wrong, because pulses_get() does not accept any arguments).

@jlcoleman @troy-salt There are quite a few screens around, usign all similar chip sets. Typically the have a separate SPI channel port for display and touch screen. @mcauser at the microypthon.org forum has a lot of different micropython drivers. Look at his repository https://github.com/mcauser. Displays are available at plenty stores. I used e.g. to order from www.buydisplay.com, especially for larger (>4") displays.

@paul-thornton I seem to get the notification now, but I'm guessing it's the mentions specifically, since I turned on the "replies in topics you watch". I'm pretty sure it's not browser related since it's not in the notifications view, but I'm using google chrome Version 71.0.3578.98 I'm guessing you get the notifications because of the reply and you're watching the topic, not because of the mention. I'm going to put mentions on emails only and replies on notifications. That should send me an email when I get mentioned and a notification because there's a reply if you reply to this topic.

@timh I've already implemented internal watchdog but it doesn't help in case of Guru Meditation Error. @Martinnn You and I have the same problem. Thank you for suggestion, as I can see this watchdog times is not in a form of a development board like this one: https://shop.switchdoc.com/products/switchdoc-labs-dual-watchdog-timer-board-for-arduino-raspberry-pi?variant=3340467699742. Am I right? Thank in advance.

@jcaron any news?

I'm impressed with the immediate feedback! I'll let you know how it goes when I get a chance to look at this again. Thanks

@einarj said in Expansion board 3.0 power consumption: @crumble Your initial answer was using the Pycoproc together with the expansion board 3? Yes. You came back with i2c problems. The Pycoproc is used by pysense and pytrack as well. All 3 boards use the PIC for handling firmware update, deepsleep and so on. But there is a chance to run into this i2c problem - depending on firmware version and your hard-/software setup.
