I'm considering hacking the ESP-01S to access the ADC line. The voltage range for the ADC is 0-1.1V, not the full logic range of 3.3V. My question is whether providing 1.1-3.3V to the ADC line harms the chip or whether it merely saturates the ADC so that it returns 1023 (10 bits) for any voltage abo...

Okay. Thanks. I realize a lot of folks manually wire GPIO0 to ground, but I'm using one of those USB programmers with a physical switch between UART and PROG mode, so that isn't a wiring issue. At any rate, it's reassuring to see that prog mode should indeed circumvent this sort of issue. That's wha...

I knew doing this would be difficult to back out of, but I didn't think it would be impossible. I didn't expect it to permanently brick the board, so I suspect I haven't figured out the solution yet. I wrote a main.py that initializes pin 1 (TX) to an output pin. So, now, whenever the board boots up...

Yeah, but this is what I have lying around, so I'm going to work with it.

I working with an ESP-01S with the intent of creating (many) houseplant monitors. The ESP-01S will connect to one of those fairly ordinary soil moisture sensors (unfortunately the resistive types for now, corrosion issues notwithstanding), including the ADC-potentiometer board in between the sensor ...

Thanks!

Noted for further analysis. Thanks.

Thanks. I like your idea of first handing things off to a local Mac and then dealing with further transmissions from there. I'll still have to create and run some sort of socket server on the Mac I suppose, but I can dispose of all the authentication complexities and just write a straightforward dat...

I can REPL to my ESP-01S via USB and I can get the basic MicroPython network routines going. I can connect to my home wifi and successfully replicate the Star Wars ASCII demo from the docs. That all went swimmingly. What I would like to do is use the ESP8266 (or ESP32, I have both available) to gath...

Between the release of the PyBoard D and the OpenMV H7, it's looking up to be a pretty remarkable spring for MicroPython projects. I'll have to decide what I want to do.
