IT WORKED! Your command differed from mine in two ways. It explicitly stated the firmware size and it indicated a different firmware mode. So I tried it again, reverting each of those parts to my original command, and the part that is relevant is the -fm change. I can still use --flash_size=detect a...

Thanks!

I just bought five ESP-01S boards in a batch, so they're all identical. esptool had no trouble erasing them or writing firmware to them, but when I restart them in UART mode, all I get is the usual single brief LED wink. No terminal REPL and no MicroPythonXXX wifi network. These are 1MB boards. I ha...

PyBoard D is only listed on the official store, based in the UK. The international distributors, such as Adafruit, Sparkfun, and RobotShop don't list the D on their websites, only the v1.1. Can the D only be obtained from the UK?

Thanks.

Thanks.

Is time.sleep() (or utime.sleep()) the same thing as machine.lightsleep()? They take slightly different arguments (float seconds vs. int milliseconds), but functionally are they doing the same thing? Is there a recommendation between the two? Are the functions under the machine module meant to suppl...

All right, so yours is working. Thanks. I have two completely different D1 minis (both clones, I admit) and both suffer a fairly widely experienced problem in this regard. Waking with an alarm just doesn't work. Hard resetting works, and resetting from the "zombie" state of an erroneous alarm wakeup...

Yes, sorry. I see your point. I did write that. I was referring to the only "logic" connection, pushing aside the issue of actually powering the sensor, and furthermore that ground should be "common" amongst components. But you are right that such details need to be clarified.

Thanks!

It isn't immediately and necessarily clear that one should need to connect GPIO16 to RESET to enable wakeup on the reasoning that people might want to use the pin for another purpose. We are at least two levels of abstraction removed from the chip. Sure, on the ESP8266, you have to connect them dire...

What do you mean "without ground". The sensor has a VCC and a GND line. Those are connected to the ESP board's VIN and GND lines. Then I connected the sensor's signal line to the RESET line. I'm sorry, but I'm not understanding what you're trying to explain about my setup.
