Running NeoPixel on XBee3 with MicroPython

Question

Hi,

Is it possible to run NeoPixel from MicroPython? I was not able to find any compatible drivers (there were some who relied on SPI which the XBee3 doesn't seem to support).

Answer 1

No, the SPI port is not accessible from the Micro Python interface.

Answer 2

In my opinion it should be very easy to port the esp8266 NeoPixel driver (https://github.com/micropython/micropython/blob/ddb53c9458381f71d896ebba60234716f1b156d9/ports/esp8266/modules/neopixel.py and https://github.com/micropython/micropython/blob/0fff2e03fe07471997a6df6f92c6960cfd225dc0/ports/esp8266/espneopixel.c) to XBee 3, because there is no need for SPI, but only GPIO.

Is it possible to compile C code to be used with XBee MicroPython?
I tried following "Native machine code in .mpy file" guide: https://docs.micropython.org/en/latest/develop/natmod.html. I managed to compile a C module, but whenever I try to import it on the XBee, I get a "incompatible .mpy file" error.
Have you tried running a C module in XBee MicroPython?

Answer 3

If we chain multiple NeoPixel together we are able run this with MicroPython. We can use MicroPython to control NeoPixela.
