Crowdfunding of ESP32 port development

What is your opinion on crowdfunding of ESP32 port development? If several forum members would agree on which features should be developed and would be willing to participate financially a developer could be hired for several weeks, preferably one of regular contributors to the repository. Another o...

Re: New ESP32 development board DMtech DEV01 with NB-IoT interface

Prototype of the board was assembled. Initial test shows that the board can attach to NB-IoT network and antenna sensitivity seems to be pretty good as well.

New ESP32 development board DMtech DEV01 with NB-IoT interface

Hi, I am developing new development board based on ESP32-WROVER. Most interesting feature is onboard NB-IoT modem Quectel BC66 and cellular antenna. It will probably be released as open source after successful tests. Can be used on top of custom carrier board as some sort of control/communication mo...

Re: Differences between Micropython ports for ESP32 and ESP8266

I am glad to hear that the ESP32 port will be developed and maintained. I will start testing soon. I want to use Pycom WiPy 3.0 as a hardware because it contains very good switching regulator (LM3281) and I want to test deep-sleep currents as well. Should micropython.org port work on this board or s...

Re: An error which occur in time

Maybe this i...

Re: Differences between Micropython ports for ESP32 and ESP8266

Hi all, based on the fact that Pycom team tends to move their focus from dev/OEM module development to consumer products (PyGo/PyLife) we are considering to build FW stack of our products on micropython.org ESP32 port. I did not follow this forum very often for more than a year. Looking at the githu...

Re: I2C with new hardware API on CC3200 port

This code worked for me:

Code: Select all

i2c_scl = machine.Pin("GP12", mode=machine.Pin.ALT, alt = 5)
i2c_sda = machine.Pin("GP13", mode=machine.Pin.ALT, alt = 5)
i2c = machine.I2C(scl=i2c_scl, sda=i2c_sda, freq=100000)

usocket.socket.settimeout() not working on CC3200 port

I tested on my own build from 12.6.2017 using simple code: s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.settimeout(5) s.bind(('', 80)) s.listen(5) conn, addr = s.accept() In this point s.accept() hangs indefinitely if there is no connection from other host. Some time ago I submitted GitHu...
