Re: Espressif announces ESP32-S2

Is anyone aware of any development work to port MicroPython to the ESP32-S2? There seem to be some significant differences, like having one CPU core instead of two, and USB OTG support, both of which might need a reasonable amount of work. It has less RAM and internal EEPROM but the fact that it app...

slimDNS: a pure Python mDNS implementation

For some time I've been frustrated by the lack of multicast DNS support in the MicroPython implementations for the ESP8266, and more recently the ESP32, so I finally decided to do something about it. To that end I'd like to present slimDNS (Simple, Lightweight Implementation of Multicast DNS). It's ...

Re: Our new dual band WiFi/bluetooth module

This certainly sounds interesting. I would love to have a reasonably powerful MicroPython device with a Bluetooth interface and API stack. Do you have an idea what sort of price you would sell this at? The WM-BAN-BM-13 has NFC functionality too; is this connected in the device that you created? Give...

Re: Ideas for next evolution of pyboard

I'd like to add my support for a LiPo battery charger. Many of the projects I have built myself or seen from others have been 'stand-alone' devices which need to be battery powered. A built in charger circuit so that all you need is to plug the battery in makes doing this very simple. As many other ...

Re: ESP board doesn't support std{in,out,err}.buffer

I managed to get the tool chain working and build my own version of the ESP8266 port. Simply adding the one #define to the mpconfigport.h file seems to be sufficient to make this work and it seems to be working fine on my card. Hopefully this can get switched on by default in the main line builds of...

Re: ESP board doesn't support std{in,out,err}.buffer

It would be useful to have the buffer object. In the meantime you can use the machine.UART(0) object to access the serial in a binary way. Yes, I realise that I can reach the raw UART directly by name but that makes the code non-portable. I'm trying to communicate with a variety of boards from anot...

ESP board doesn't support std{in,out,err}.buffer

Is there some reason why the builds of MicroPython for the ESP board don't support the stdio 'buffer' support for raw access to the terminal? The standard stdio streams do a bunch of translation between '\n', '\r' and '\r\n' on input and output, which is desirable for certain console operations but ...

Re: Driver for Adafruit GSM FONA module

Has there been any progress on a network/socket driver for the FONA module? The device supports abstracted TCP and UDP connections as well as DNS lookup, so much of the work is already done in the module. I can't find any documentation regarding how to write network drivers but if someone can give m...

Can UART data wake the pyboard from pyb.stop()?

When the pyboard is put into low power mode using the pyb.stop() call, is the UART hardware still running? If so, is a UART interrupt sufficient to cause the pyb.stop() call to return? I have a data collection application in which data will arrive at irregular intervals over a serial interface but i...
