Did you switch off flow control in putty?

if chunk is a bytes object, you may need:


b"".join(chunk.split())

e.g.
"".join(chunk.split())

On device using a Ch340G like the Wemos D1 mini or the Wemos Lolin32 lite I often get transmission errors beyond 230400 baud, using debian Linux. Not problems with CP210x or FT230 devices.

Ther error is in the function you call: def I2C_ReadRegister(Rd_Addr): global i2c, sensor result = i2c.mem_read(1 , sensor[0], Rd_Addr, timeout=1000) if isinstance(result,bytes): if len(result) > 0: return[0] The last line should be: return result[0] The line further below the one you flagged as err...

Try Dave Hyland's rshell.

I piggy-backed an ESP32 LoLin32 lite with a RAM chip as shown here: https://loboris.eu/forum/Thread-Info-Upgrade-ESP32-board-without-psRAM-with-4MB-8MB-SPIRAM. It also tells the source for the RAM. A little bit tricky for my old eyes, but it works. I just tried it with today's commits with psRAM sup...

This shield is just an ESP8266 connected to an UART. You can do the same with any ESP01- module. Both @pythoncode and me (and maybe others) had the idea of using that as WiFi interface. But at least for me the task seems to laborious. Maybe the bew MACRAW interface makes it a little bit easier to ha...

You can do the same in viper with a short loop. You may have to disable irq for that, to make to stable.
There are a few words about viper in the docs: http://docs.micropython.org/en/latest/p ... de-emitter

If the naming in assembler is too tricky, you could use viper code. It typically needs twice the time of assembler code, but you can create simple variables, give them the names you like and use the control structure of Python-
