Can I let Timer.counter() add 1 when Pin level changed.

.deinit() is affect to ESP32 port, I confuse them, on PyBoard, use sd.power() instead,
before eject SD card,

True

then re-insert SD card,

True

If none SD card inserted, execute sd.power(0) or sd.power(1) will return False.

How to do that?
Thanks.

Interest on it. Can we refer ESP32 network.LAN() implement, it works fine, it initialize with: lan = network.LAN(mdc = machine.Pin(23), mdio = machine.Pin(18), power = machine.Pin(17), phy_type = network.PHY_LAN8720, phy_addr = 1) Relate link: https://github.com/micropython/micropython/blob/master/p...

Try sd.deinit() after uos.umount('/sd') or eject SD card, and initialize 'sd' object again after re-insert SD card.

That section doesn't mention DHCP at all. So I tried to build firmware for my PyBoard like this: make BOARD=PYBV11 MICROPY_PY_WIZNET5K=5500 MICROPY_PY_LWIP=1 (PYBV11 for PyBoard v1.1 in my case), and it helped, so apparently DHCP is implemented in lwIP. Good, it works. I think the lwIP module alrea...

In some SSD1306 use case, just need to change specific area contents only, or likes Arduino serial plotter scroll the graphic from right to left, if use SSD1306.fill(0) then redraw entire(full screen) graphic, it will be slow and blinking extremely, someone could give some examples by other better m...

The document .pdf version isn't build automatically by Readthedocs?

I want to let pyboard works as I2C slave like SSD1306, BME280 ... , when receive command, do something, why those devices can do that with 2-wires ?

Thanks.
