They work fine for me and seem to be reliable. I haven't compared them against anything else though.

That's exactly the kind of help I need. Best practice!. Thanks Peter.

All fixed with following code: import pycom from machine import UART import time uart = UART(1, baudrate = 9600) pycom.heartbeat(False) pycom.rgbled(0x000000) on_frame = [b'\x7E', b'\x00', b'\x10', b'\x17', b'\x00', b'\x00', b'\x00',b'\x00', b'\x00', b'\x00', b'\x00', b'\xFF', b'\xFF', b'\xFF', b'\x...

I need help with sending a 20 byte buffer to an Xbee via UART. The project has been tested and works using an Arduino. The Coordinator Xbee is attached to a WiPy 3.0 via UART. I am able to read a 22 byte frame from a Router Xbee via the Coordinator using the following: import pycom from machine impo...

Thanks. All fixed with:

pin0.set_pull(pin0.NO_PULL)

Using a Keyestudio PIR designed to operate at 3.3v http://wiki.keyestudio.com/index.php/Ks ... ion_Sensor

When triggered the signal goes high and is outputting 2.9v. I'm using pin0.read.digital and I'm not getting an on reading when it goes to 2.9v. Is this normal?

Thanks. This works, with one small problem. I am only receiving 'buffer' contents minus the last two characters. In this case I get 'Hello Wor' Can't understand why I'm losing the last two characters. The good news is that the microbit reconnects the usb! Code follows: from microbit import * buffer ...

Thanks both. Another question. Do I need to disconnect the usb to computer cable from the Micro:bit for the UART to work?

I have just started with my Micro:Bit having used Arduino previously. I am trying to connect an Xbee wireless module to the Micro:bit (I've used them successfully before with Arduino). I'm using the instructions in the BBC micro:bit MicroPython Documentation, Release 0.0.1. Section 2.1.8 UART. Pin0 ...
