Re: [PIC32M]MicroPython port to the PIC32M

Matt, You don't need a development board. These things come in 28pin DIP packages, plug straight in breadboard. Only needs one external capacitor, plus another cap if you want power supply de-coupling. Generally don't need crystal as they run OK on internal RC oscillator. Although, you will need spe...

Re: ESP32 Long Range Mode 1 km

Bumping this thread. Is there any information available on the status of micropython using WiFi Long range mode with ESP32? As I understand it is a proprietary 802.11LR mode. It is functional in the ESP-IDF and supported by Pycom micropython port. quote from the link below. Enabling the mode is a si...

Re: [PIC32]Experiment on PIC32MX170F256B, gc.collect() crashes.

I'm not sure if PIC32 port is still of any interest
I have been using PIC32MX and would be interested to see how it performs under micropython.

Are you interested in making your port public and published on Github?

Re: ESP32 AP mode maximum number connected clients?

Thanks Jimmo. Would be helpful if there was a possibility and an option to increase this, I guess it would be subject to all the other underlying complexities. Another useful stand alone wireless network would be esp-now, not relaying on common AP. From memory, there was some development happening i...

ESP32 AP mode maximum number connected clients?

Would like to know how many WiFi STA clients, predominantly micropython ESP-32 and micropython ESP-8266 can be concurrently connected to one micropython ESP-32 node set up in AP Wifi mode? All of these nodes to run latest micropython firmware based on whatever latest espresif SDK. There are various ...

Code: Select all

import sys
import select
import time

while 1:
  time.sleep(0.1)
   
  while sys.stdin in select.select([sys.stdin], [], [], 0)[0]:
    ch = sys.stdin.read(1)
    print(ch)
    
  print("prove it doesn't block")

Trying to disable REPL from Uart0 on ESP32

I need non blocking stdio character reading through USB-Uart0 port on esp32 development board. As I understand there is NO non-blocking stdio reading available. So I would like to disable REPL from USB-Uart0 port and use the same port with standard Uart functionality including non-blocking read. To ...

Re: mu editor for micropython

Auto serial port detection on Windows 7 appears to select first detected port even if it is used with other connection.

I don't see any configuration options to select and configure serial port?

Re: C module programming reference

So, in summary ....it would be great to have a minimal example C user module in the master branch, that newbies could hack on and get up to speed. The real learning curve here is not how to write C code, but how to mesh new files into the make. That step could be trivial it the instructions were ac...
