datetime no attribute '__new__'

I'm trying to use the datetime module from micropython-lib. I've copied datetime.py into the modules directory in the up-to-date esp8266 port and built the firmware. I had to remove a couple of other frozen modules to get it to fit. Code builds and loads and runs but when I try to import the module ...

Re: Feather pyboard

Hello again. I've got your design files open in KiCad to see if I could maybe figure out why your charge controller burned out. The only problem I see is that when you're on battery power the VDD input on the charger chip is brought to VBAT minus the forward voltage drop of D2. The datasheet specifi...

Re: Feather pyboard

:cry: /edit: oh man, I just connected a battery and the charging chip burned out. That's the part of the design I took from Adafruit boards and assumed will work. I just found this thread and I'm delighted that you've undertaken the build! I too like the feather form factor and have wished for pret...

Re: Ideas for next evolution of pyboard

Also note that several STM NUCLEO boards are supported, which include Arduino pin-compatible headers and make it possible to use many Arduino shields Correct. I could purchase STM32 boards and Arduino shields and make things work. Though my purchases wouldn't contribute to MicroPython's continued d...

GA release v1.8 ssd1306

I flashed the bin that was sent out yesterday into my feather huzzah. I did do a full erase beforehand using esptool.py. When I try importing the ssd1306 module I get a Memory Error exception. I've tried deleting webrepl beforehand to try to free memory but it still produces this exception. I assume...

Re: Ideas for next evolution of pyboard

I just found this post. Hopefully I'm not too late to chime in. Let me provide my input by means of a story. First, my background. I have been an embedded developer for the past 15+ years using about a half-dozen different architectures at the C, assembly, and HDL level. My passion is to make things...

Re: ESP-Board Variations - Availability and MicroPython Support

our current idea is to use native chip GPIO numbering and avoid adhoc board-specific numbering I think this is an excellent idea that will serve to reduce confusion in the long run. I would expect that the community could quickly map out i/o pins for the dozens(?) of modules that may exist. I'd be ...

Re: esp8266 compiled error

I just ran into that myself.
If you scroll down in the README.md in the root repo you'll find the answer in the external dependencies section:

Run the following in the root of your copy of the repo:

Code: Select all

git submodule update --init
This will fetch additional files and allow the build to complete.
