Re: Which sensor can capture blowing action?

What about a sound sensor? Blowing into a microphone can be quite loud compared to background noise.

Re: nRF24L01+ specification ?

Looks like it was created 6 years ago by dpgeorge for use on the pyboard, which is not short of pins.
I guess those who have used the code have not contributed back support for the IRQ feature.

You may be able to pinch some code/ideas from it.

According to the Nordic Semi website, yes, that Sep 2008 datasheet is the most recent: https://infocenter.nordicsemi.com/pdf/nRF24L01P_PS_v1.0.pdf https://infocenter.nordicsemi.com/topic/struct_nrf24/struct/nrf24L01p.html You can find an example here: https://github.com/micropython/micropython/tree/...

Re: MCUDev Black STM32F407VET6 + STM32F407ZET6 dev boards

Perhaps it's time for a new thread. If you are using I2C with a char lcd, I am assuming you're talking about driving it with a PCF8574 or a MCP23008/MCP23017 backpack. https://github.com/dhylands/python_lcd has examples using both, and also plain old 4 or 8bit GPIO. The ESP8266 examples are compatib...
