Re: Convert a image and show in OLED display

Hello, I was able to put two and two together to figure out what you may be looking for. 20180615_114602.jpg Based on what I have done for this project https://github.com/joewez/ESP-Widget I use a simple text file that has monochrome bitmap encoded in hex values. For example, the graphic you link mi...

Re: Differences between CH340 & CP210X Boards

@bitninja a little off topic, is it an old motorola phone turned into a pocket computer you are using as a terminal? No, it's actually a Raspberry Pi Zero W, LCD, USB Hub and battery stuffed into a 3D printed case... in the form factor of an iPhone 4. Then I use a cheap slide-out bluetooth keyboard...

Re: New Lolin D32 Pro with 4MB PSRAM

I suppose the spacing of the headers is the same as the older Wemos D1 Mini Pros... so that at least the shields should still work. Nice to see they are using the MicroPython pin numbering scheme now!

Re: vgkits-vanguard - Learner-oriented tools for ESP8266 micropython boards

Very nice! I'll have to give it a spin when I get some time. I'm glad someone has thought more about the educational benefits of a physical computing kit. I think there is a barrier to learning to program in that it's usually restricted to just doing stuff on the computer screen. Some learners may r...

Re: Running webserver and other code simultaneously

You can use frozen modules for the code that is stable and definitely required. Pre-compiled modules may be accomplishing the same thing... I have not used those yet. I just got comfortable building my own firmware and then added the modules I needed into the build. Second... garbage collect often.....

Re: PyConAu Talk - any suggestions?

There's been an IoT track at PyConAu for a couple of years now... That would be interesting to me... an IoT talk that had some practical examples of MicroPython being used for IoT devices. This would probably focus on the ESP boards but I think that's ok. By now, MQTT is pretty well represented on ...

Re: PyConAu Talk - any suggestions?

It would seem that for an audience of mostly desktop Python users, a talk would need to give some kind of gentle introduction to embedded programming in general. Even idea #2 would need some mention of C or C++ and something like the Arduino platform. I think you should forego the comparison and ins...

Re: Running webserver and other code simultaneously

Here is a simple web server based on the uasyncio example, that I know works on the ESP8266 and the D1 Mini. I have yet to implement another coro but perhaps Peter's tutorial will help you with that. # # Simple HTTP server based on the uasyncio example script # by J.G. Wezensky (joewez@gmail.com) # ...

Re: Chinese Micropython Clones(?)

Don't get me wrong, I am happy with the board... it's just some of the finishing work like the headers... they were soldered in pretty quickly apparently... 20180515_185641.jpg Notice the angle? And some of the soldering is kind of blobish. 20180520_191754.jpg It's not terrible by any measure... the...
