Re: TTGO T-WATCH-2020

Hi, I got mine a couple of days ago... I couldn't resist. It's a nice gadget. Not exactly a champion in build quality but running MP on it is fun. In regard to Franz repro, I could not run the paint function as it seems there is something wrong with the touch recognition. But it is very much fun to ...

Re: A novel clock display?

Hi, Late to the party. That is very neat. Just wanted to say that there was pepple with the pepple watches using an colour eink display. You could program your own watchfaces and some looked similar like what you showed. pepple watches were great and advanced their time by many features unseen even ...

Re: Season of Docs : MicroPython

Hi, sounds like a neat idea. I do some teaching with Micropython for some classes and albeit docs for usage are available exactly the internals are the most difficult part to find information about. Second to this would be documentation how to port Micropython to another board or another architectur...

Re: How to eval bytecode from network?

Hi, people always fear this "wear out the flash" thing. I challenge this. Unlike you have code which constantly writes to the flash (like writing log files), I would not see that a "pull an update at start" has any chance to wear out the flash within the usual lifetime of a system. Even if the flash...

Re: MicroPython on PIC16F684

Hi,

the PIC16F684 is to small to house Micropython.
For the same reason, I guess they ask you to write assembly ;)
If this project is open minded, you might be able to switch the controller?

Re: Counting pulses from an electricity meter

Hi, is there any reason you want to write to your influxdb database every 250ms? The ESP should be powerful enough to do the math and e.g. send an average value every minute. Or, if you really want to get all the raw data, you could create a buffer and send 100 values in one go, which would result i...

Re: plant watering

Hi, this looks like a good start. You can add code using the code tags. Just mark the code with the mouse and press the </> button. This adds the code into its own window with some better formatting and an own scroll bar, thus it does not take up much space. Did this for you on your last post. As fo...

Re: plant watering

Hi, That should be relatively simple. The relay does the main work for the pump. All you need here is a I/O pin to be set high or low. That is not different to any LED-example you find in the tutorials and documentation. The soil sensor delivers an analogues signal. This can be read in by Micropytho...

Re: Micropython Education - Project proposals, ideas and help requested.

Hi, I gave a similar lecture last semester and one of the main advantages in my opinion is the different workflow which includes a much easier debugging routine if things go wrong. I told the students that they can use python, ipython or micropython on the PC to craft many parts of the internal stru...

Re: MicroPython on Casio fx-CG50 Questions?

How interesting that so many MicroPython-people are also HP and RPN fans ;) Decades of HP48GX user here, which unfortunately, does not work anymore. I got an HP49G recently from a colleague.... However, I don't use it nearly as frequently as before, as my smartphone runs an HP48GX emulator and the P...
