WiPy 1.0: Framebuf module? Yes/no? When?

Is there any schedule for when the framebuf module will be available on the WiPy 1.0? Here's a post from 5 months ago where it was said to be coming "shortly". And here's a post from 3 months ago where there was a firmware containing framebuf promised for "this week". I just flashed the v1.9.1 (rele...

Re: PCD8544 driver module (Nokia 5110 lcds)

That's why the drivers shouldn't try to create their own spi objects, but instead take one as a parameter. Different platforms have different ways of initializing spi and different parameters allowed. Oh, it takes an SPI object as parameter. But for some reason, different platforms have completely ...

PCD8544 driver module (Nokia 5110 lcds)

In a thread in the Hardware Projects group there was a non-working module for PCD8544 lcd modules. The PCD8544 controller is used in e.g. Nokia 5110 LCDs. Since I also ordered these type of lcds for my WiPy, I wrote a module myself. Basic functionality works fine. I'll spice it up in the near future...

Re: Driver for LCD display Nokia 5110

I just received those displays from China to play around with my WiPy. I hope I'll find some time on the weekend. What I noticed from reading the datasheet : The first bit is the MSB, not the LSB like in your code. Also, data is sampled on the positive edge of SCLK, so I believe phase needs to be 0 ...

Re: Unreliable Operation: FTP, Telnet, Power, ...

While we're at it: Midnight Commander also shows a strange symptom with the WiPy. FTP basically works, but after I changed to the /flash directory and press Ctrl-R (Refresh) a couple of times, the WiPy will sometimes return the contents of /flash (correct) but sometimes it returns the contents of / ...

Re: urllib for Micropython

I also wanted to start a HTTP module (need GET and POST to communicate via Open Spherical Camera API) and just finished the URL parser which is somewhat oriented on the standard urllib.parse module. Maybe you can make use of it: https://github.com/mbirth/wipy-theta/bl ... er/http.py

That had nothing to do with the mode as @danicampora explained there.

Re: Simple terminal (VT100) editor widget

What are lazy imports? It's loading your libraries when they're needed instead of on top the .py file. So instead of: import os def whereami(): print(os.getcwd()) You'd do it like this: def whereami(): import os print(os.getcwd()) This way, os is first imported when it's needed instead of being imp...

Re: Simple terminal (VT100) editor widget

on my WiPy but it seems to run out of memory even when freshly booted. Any ideas? For me it loaded fine after I rewrote my main.py to use lazy imports and did a gc.collect() before trying to import wipye. mem_free was around 52-53k. However, I was not able to do anything once it was loaded. It didn...
