Re: Tests on ST evkits F091RC and L432KC

You have not import pyb, you may try as below:

Code: Select all

import pyb
from pyb import Timer
tim = Timer(1, freq=1000)
tim.freq(0.5)
tim.callback( lambda t: pyb.LED(1).toggle())

And I plan to design a new board, with very small size and lower cost, no onboard SD socket, no accelerometer.

You may try transshipment service, buy something in taobao, then transshipment to Australia.

Re: My new PYB Nano board is coming

The link above is not from me, the board is less than $9, but postage is much higher.

The new taobao link is below:

Re: My new PYB Nano board is coming

PYB nano v2 is also out, upgrade MCU to STM32F411, add 8M byte flash, so it can store more files.

Re: My new PYB Nano board is coming

PYB Nano usage is same as PYB V10, you need a terminal to running REPL.

PYB nano V1.1's firmware:

Re: Problems pasting 190 lines of code into PuttY

When using paste mode, you need enough memory, or you may paste code multiple times.
