Providing you are using the library proposed by jimmo you need to declare a rotaryIRQ() object. This object handle all the interaction with the encoder you just have to read the value method. You define the min and max value. When you turn the knob the value is increased/decreased. You should look a...

Perhaps you can try to adapt Adafruit's CircuitPython driver

Obviously, the Arduino UART monitor puts the handshake lines in a state that makes the ESP32 boot in download mode. Arduino UART monitor is not REPL friendly. Arduino UART monitor works in line mode. REPL expects a terminal working in character mode. You'd better use a terminal software like putty o...

baudrate=20000000,
I've tried slower and faster baud rates.

You surely shall slower the baudrate. ST7735 datasheet gives a serial clock not shorter than 66ns (that's 15MHz).
While testing (maybe on breadboard) you'd better slow down to 4MHz just to be sure.

Usually, this kind of problem arises when the file is open at the time of the power outage. Sofware solution So you can close the file every time you end writing a file. This will limit the risk of filesystem corruption. But don't suppress them of course. Hardware solution You can put a supercap bet...

There is no documentation for ESP32. Usually the ESP8266 one do the trick.
You only have access to documentation for the pyboard because you are in the "latest" release.
Select "1.9.4", you will then be able to choose between different boards.

Cooool
Thanks a lot

Hi, here is the configuration I use: Lilygo T4 board with ESP32 and SPIRAM MicroPython ESP32_LoBo_v3.2.20 - 2018-06-28 on ESP32 board with ESP32 I use curl to get a json file from wunderground weather forecast using their API import curl, ujson res=curl.get('http://api.wunderground.com/api/my_access...

Hi,
DS1307 is now an integrated circuit "from the past". It works on 5V, if you power it with 3.3V it may not work.
You'd better switch to a DS2321 wich is designed to work from 3.3V supply and is much more accurate.

There are no doc for ESP32 port but instructions for ESP8266 can apply with minor modifications. Providing that Python is already installed on your computer. First step is installing esptool pip install esptool second step is downloading the firmware on MicroPython dowload page Then you follow instr...
