[Microbit-Python] UART Pins

[Nevil Hunt]

Thanks David!
 
I take it using P3,4,5,6,7,9,10 or 11 would interfere with the LEDs & Switches on the micro:bit.
What about using the SPI or I2C pins? Is there anything on the micro:bit hanging off any of these pins that would conflict with the UART?

Read the docs ;-)

You can specify any other pins you want by passing the desired pin objects to the tx and rxparameters.

Hi David,
 
My micro:bit diagram shows the I2C and SPI pins on the edge connector. Which are the UART Tx & Rx pins?

How about a BBC micro talking to a BBC micro:bit over serial? The RS422 interface at the back of the original beeb is just a UART. Need a level shifter, then bring into UART pins on the expansion pads at the bottom of the micro:bit and use MicroPython UART object.
