Robert,

That works. I'm relatively new to micropython and am inclined to do too much copy and paste rather than being systematic about learning all aspects of the language. This is a good example of that. Thank you for your guidance.

I am trying to change the range on the accelerometer. This is done by setting bits in 0x1C. I modified the class accel() and added this piece of code. I had the register lines in the __init__ part initially and just moved it here for further debugging. The print statement always returns zero. def ge...

At the risk of insulting someone here I'm surprised at the low level of activity on this forum in general. Indeed searching for other micropython forums reveals little or none out there. Considering the vastness of the web and the application of micropython coupled with the cheap and cheerful ESP ra...

I had a problem with the "MemoryError: memory allocation failed" error. I was using the __init__.py structure. After trying to remove offending code from my library module (~10k) for days the problem persisted. Finally I split the module into two 5k modules and the situation resolved itself. Now I h...

Has anyone implemented this method in micropython?

The Arduino (ATMega 328) has a timer register that can be preloaded and set to pulse an I/O pin on overflow so that a 38KHz output waveform is generated outside of program control. Has the ESP8266 anything like this? Bit banging with micropython is not fast enough I'm sure.

Just tried using 4KHz PWM frequency and the flickering is just more frequent.

I realise that it might not matter in most situations except if you created a mood light with it. Instead of calming you down it would probably drive you crazy!

I have rejigged Arduino and micropython code to produce a Function that returns the temperature with input parameters of Pin No and Resolution (9-12 bits). def Temperature(resolution, dsPin): dat = machine.Pin(dsPin) ds = DS18X20(onewire.OneWire(dat)) roms = ds.scan() for rom in roms: if resolution ...

I ran up a piece of code on the Arduino IDE to do the same thing. There is no flicker here. Seems to be a micropython issue. Not having captured the flicker on a storage scope I am guessing (visually) that it has a duration of maybe around 10mS. Again not having tried it on a motor I suspect that it...
