NRF24L01+ communicating with Microbit
I have used the NRF24L01+ between two Arduinos. Has anyone managed to talk to the microbit using this module. Nordic tell me that if both radios use the Nordic Semiconductor’s Enhanced ShockBurst protocol (ESP) then all should be fine. I came across just one YouTube video where a guy does some simpl...

What is assembler?
I am wondering are the assembler instructions begun with @micropython.asm_thumb the actual platform specific instructions or are they some sort of generic instruction set working on the Micropython interpreter at a very low level. I would image that the assembler instruction set would be quite diffe...

i2c.readfrom timeout
I am talking to my Arduino from ESP8266 via i2c. The Arduino code can sometimes take up to 36mS to complete the code that responds to the i2c.readfrom command at the ESP. After a few transactions the ESP throws an error: File "IO.py", line 110, in read OSError: I2C bus error Does anyone know if ther...

import issue
I have a module that I import after "from machine import I2C". The module code does not recognise the i2c name unless I put this line in the module as well. What's the explanation?

Re: Radio not working
Thanks lujo,
I had read about the complex packet issue before and forgot about it! I followed your link and at your advice I used Phil Hall's implementation. All seems good now for transmit and receive packets.

Radio not working
I set up a Master / Slave arrangement using Makecode plus a small bit of Javascript, it works great. I then started to rewrite the Master in Micropython and the Slave receives no signal. I even tried looping through all of the channels but no joy. Before I get into details is there anything blinding...

Incorporating MyLib.py into the flashed hex file
I want to put together a large MyLib.py. Currently this kills the microbit once it passes a certain size throwing memory allocation and parser errors. It would be great if his library could be flashed and then allow the user to call it for their own smaller programs. I want to use the microbit to te...

Memory allocation and parser errors
Just started micropython on the microbit having spent some time writing code for the Esp8266. With relatively small programs I'm getting memory allocation errors, and errors about the parser unable to handle scripts. Is micropython very limited on this platform compared to the Esp8266?

Re: LCD driver for micro:bit
I used your driver but whenever I wrote more that 10 characters on the LCD I got a Memory Allocation error. I tried using .mpy files instead but it appears that the microbit does not recognise these, reporting not found. Eventually I stripped out all of the variable declarations in your code and rep...

Re: My IDE configuration using Notepad++, ampy and Tera Term
I downloaded the zipped binary but it will not connect to my ESP8266. Refresh seems to be doing something but nothing appears. I edited the xml file to launch my TeraTerm: <add key="TerminalApp" value="C:\Program Files (x86)\TeraTerm\ttermpro.exe"/> <add key="TerminalAppArgs" value="-serial COM4"/> ...
