I am puzzled: as_gps.py should ignore unsupported sentences, just incrementing debugging counters. See this line . By default such sentences should be ignored. There is an option to handle them in a subclass by overriding the parse method. I am also puzzled by your having problems with stationary de...

You may get better results using uasyncio instead of threading.

... That matches my observation that the ESP32 port here with SPIRAM is slow... Indeed, that seemed the only explanation for the discrepancy. In particular gc is slow as it has to trawl through the whole RAM. This shouldn't affect these tests as it is performed prior to each run, but in general it ...

I raised this issue last summer. I don't know why it hasn't been fixed.

You might like to try @micropython.viper def do_int2(s: int, d:int, m:int)->int: sdm = s * d + m // 2 return sdm // m - (sdm - d) // m I can't replicate your timings, even increasing the clock to 240MHz mine are slower: tested on an ESP32 with SPIRAM. But Viper did produce a significant improvement....

I think the best approach is if you could explain what you are trying to achieve. Are you aiming to wake a board from a sleep state or merely to schedule events (e.g. callbacks) at certain future times? If the latter I can point you to simple solutions which will work on any platform and which don't...

...Is it really that hard for developers to implement a callback functionality for UART, both Rx and TX would be useful?... The benefit of callbacks is to facilitate concurrency. MicroPython achieves this with uasyncio. The following code sample handles concurrent reading from and writing to a UART...

Unfortunately the machine.RTC documentation is misleading in that some methods are unavailable on some platforms. The ESP32 currently only supports methods datetime, init and memory.

As you doubtless know, CircuitPython is an Adafruit fork of MicroPython. Most (all?) those in this forum use official MicroPython. So I suggest you raise the query on the Adafruit forum.

MicroPython can drive servos without the need for external hardware.

By far the best way to debug this would be to put a scope or logic analyser on the UART lines. A Saleae analyser (or Chinese clone) will show exactly what's going on. A few thoughts on tests you might perform. The baudrate of 1000000 is not a standard value. I would check whether the UART is actuall...
