Re: Using the tx/rx pins not for UART

Is there still any interest in this feature at all?
It would enable several devices like the sonoff 2 or 3 touch as well as connecting some other devices via serial and only using the network to interact.

Re: Software serial?

I solved my problem in implementing an arduino ic2 client library (as I had to monitor "serial" output from Arduinos) and then connecting via i2c. Feel free to check https://github.com/ulno/ulnoiot/tree/ma ... _connector if you also want to monitor Arduinos.

Re: Software serial?

Is there still something going on regarding this - anybody using it successfully? And based on which version?

Re: encryption, block cipher, simple (micro-)pythonic way to access

Thanks, need to take a closer look - I ported a native chacha implementation now, but as it's native, it's pretty slow of course (but workable for a command prompt): https://github.com/ulno/ulnoiot/blob/master/lib/netrepl/chacha.py If anybody wants to try, you can also use the provided netrepl to do...

encryption, block cipher, simple (micro-)pythonic way to access

I am working on a replacement for webrepl (based on utelnet) using a symmetric encryption layer. My assumption is that every node I am maintaining has a unique "secret" key used as base for the symmetric encryption. I consider this safer than SSL with non working certificate validation. Most of my n...

Re: Add own native library (example touch controller)

No, this doesn't look too hard and the time critical-part is anyway low level C-code, so should be doable. So, I just check out the stuff from github and set-up cross compiler toolchain and try to get going with a small hello-world based on the 1-wire code?

Thanks,

Add own native library (example touch controller)

Hi all. I have recently written a small touch library (http://github.com/ulno/libni) for the esp8266. I also designed a workshop for using this to build with students a tin foil based touch game controller (just presented on FOSSASIA 2016). However, using C in an introductory class (and especially f...

Re: ESP-Board Variations - Availability and MicroPython Support

Not sure, if this the right thread (please correct). Just tested v2 on the Espresso Lite v2, designed by Espert (http://www.espert.co/), produced by Cytron (http://www.cytron.com), supplier-list (http://www.cytron.com.my/distributor). Basic functions like a little python test-code and connecting to ...
