Cannot confirm.

stijn, I think that’s what I was suggesting, or am I misunderstanding you? since framebuf is itself a native module, you can simply link against it That doesn’t work because the required functions are all static and not accessible to the linker. You’d need to use a modified version of the module wit...

I have never done any of this, so I’m guessing here, but what I gather from looking at the code is: The setpixel function you quote is an implementation detail of the framebuf module, you can’t call it from outside (not even in C code that is part of the core). It is not part of the API of the Frame...

I suspect this is not a software issue. Are you sure that it’s the ESP32 that is drawing that much power and not something else on your development board? (I’m not familiar with it, so I can’t tell.) If trying another (somewhat more expensive) board is an option, I know that the TinyPICO is optimize...

Not undocumented, however the non-obvious part is that you also need to set authmode.

This looks correct to me. Can you explain what your problem/question is? If you were expecting something different, what is it? (In case it helps, \xc1 = \u00c1 in a string literal is the character with Unicode code point 0xc1, LATIN CAPITAL LETTER A WITH ACUTE, and \xc3\x81 in a bytes literal is th...

No (unless you use some kind of external UART-to-WiFi bridge). So that leaves the second option (adding a delay). Or use something other than console output to check if your script runs, e.g. blink an LED or write to the filesystem.

My guess is that it does run, but by the time you connect again, you have missed the output already. Try working with a serial connection (which, unlike WebREPL, isn’t disconnected at reset) or adding some delay into the script so you can catch it before it’s done.

\x34 , or as a Python literal '\\x34' , is a string of four characters. Converting it to bytes using UTF-8 gives you a bytes of four bytes, 0x5C 0x78 0x33 0x34, or as a Python literal b'\\x34' . print() outputs bytes in the literal form. The extra \ there comes from the representation as a literal,...

Is this related to the Pin.PULL_HOLD flag (of which I’m not entirely sure what it does)?
