@tlanier said in New v1.20.0 Release candidate v1.20.0.rc7:
machine.reset() does not zero the utime.ticks_ms() counter.
That does not really matter, since utime.ticks_ms(), utime.tick_us() and utime.ticks_cpu() are not intended as absolute time stamps, but only intended as to be used for time differences in combination with utime.ticks_diff(). These counters overflow anyhow after a while.
Dear support team,
Since pins with output capabilities (which don't have SD or other usefull use) come in short supply I wanted to use the P3/PWR_EN/G24 pin with a lopy4/pysense combination as an output.
Searching the docs for what the PWR_EN does, is still useless, and looking at the forum only yields unclear 2 years old discussion which don't really talk about the possibility to use it as a simple GPO.
Obviously a schematic would have helped but using a multimeter I was able to figure out it was connected through 2x 9k resistors to the PIC.... but that raises more questions than it answers...
So what does PWR_EN mean? is that a reserved function which chip does it enable pwr to? does the function work currently? Where is the information to be found? I tried it with a fipy/pyscan combinaison and apparently it seems to work as an output... but the pyscan datasheet is just as obscure and I have no idea what is the effect of it on the PIC functionality.
It's been months people have been asking proper pin / function documentation and it is progressing somehow... but at a very slow speed... and makes it very difficult to plan any circuits around your boards. I know making proper docs is boring but honestly it is "not an option" when you have customers..
So thanks for that.
Hello, I am building a LoRaWAN-based IoT system and now looking for a solution for charging without USB. My device is composed of a FiPy (in LoRaWAN mode) + a pysense. To make it looks like a product, I consider a battery to replace USB cable for supplying power. But I am confused about how to choose a battery. For example:
What is the maximum voltage supply, 5.5V or 6V?
Should I consider whether battery can provide sufficient current?
can anyone give some advice?
I was finally able to upgrade a couple of GPys based on a tip I read in another post. Downgrading the Pycom firmware to 1.18.1.r1 allowed the Sequans updater to successfully complete. I then flashed the GPy back to my current 1.20.0.rc8 firmware.
@danielm said in Using PyCom products in Hungary, Telekom NB-IoT network:
In Slovak Telekom network NB-IoT service is operated in B20 using Ericsson RAN and it is possible to connect. By the way part of EPC functionalities is served from Deutsche Telekom and I expected it will be the case for Magyar Telekom NB-IoT network deployment as well.
Thanks for the info!
Thanx, clear to me now.
And there are different micropythons ( board specific ), most differences hardware related.
When you use libraries, you don't have to upload them immediately to the board, using the 'run' button.
By "See the pycom docs" you mean docs.pycom.io I suppose.
The problem I have ( and I also had with finding hardware info ), when starting with Google to find a topic, I am sometimes directed to other older documentation ( also by pycom ). So I sometimes get lost between the versions.
I have just received 2 pycom universal ip67 cases and they do look good.
there are 2 things i do have issues with and i'm just providing it as feedback.
There are no included screws for mounting the pysense, pytrack or expansion boards.
I now need to try to find the correct screws to fix board to case.
So far I haven't found any details on the correct size I should use
The usage of the punch out holes is not overly obvious and with lack of any documentation i'm curious about their purpose.
There are a number of punch out holes, some are obviously for antenna but others are not so obvious.
The rectangular punch out I assume is for USB but not sure what to use here that will maintain IP67 rating
Could we get some more information regarding this case?
if lt.light() < 10 and lt.light() < 10:
print(lt.light(), "its dark - nothing to do.")
if lt.light() > 11 and lt.light() > 11:
print(lt.light(), "Sunny day - gogogo.")```
