The decimal constant causes the expression to get float numbers. Float numbers cause a memory allocation. That alone is not a bug. You could try to use some gc.collect() in the main loop of your code, forcing a garbage collection. Since the RP2040 is effectively a 12 bit ADC, you could rewrite the e...

There is the Signal class and an abstraction on top of Pin. It allows to declare, wehter the logic is straight or inverted. In case of the on-board LED, you have an inverted logic. When using that, ON switched the LED on.

There is an open PR for the Arduino Nano connect supporting WiFi. See https://github.com/micropython/micropython/pull/7669
So it's coming, maybe even before Christmas.

BTW, I've finished the FreeRTOS version of the mimxrt port which has many advantages on such a powerful microprocessor. It works great (as far as I've tested it). I'll give some more details after some more testing... That's indeed interesting. There is already a Zephyr port for mimxrt boards. You ...

I've prepared a simple script to upload the built MicroPython firmware (firmware.bin) to the board. It can be simply used by executing:

@loboris: Do you mind if I add this script and the related Freescale executables to the Pull Request for the ARCH MIX board?

Note the space between the 4th and 5th hex values..

That's the way, 0x20 is printed. When Python prints bytes objects, it shows printable bytes as such, and non-printable as \xnn. Since \x20 is printable, the character is shown, which in this case is a blanc.

decimal 20 is hex 14. The data you wrote conmtained decimal 20, and that was read back and shown as \x14. If you want to have \x20 in the register, you have to writeit as decimal 20 or hex 0x20.

Creating a tuple of integers is not that bulky. Assigning a pin object to the tuple would be C-wise easy, but that static table of pin objects is encapsulated in machine_pin.c. I do not know whether it would be helpful in checking, whether a certain pin fired, because then the pin object has to be c...

The bitmap is just an integer. Testing, whether a certain bit is set is as easy as checking, whether a tuple contains a number - at least when one knows the binary coding of numbers. But if you like a different data type, please do so. b.t.w. it's better to have that method in the esp32 module toget...

@sergei.nz I can provide to you a firmware image with the little addition I've posted. Just tell me, which board you have, ESP32 GENERIC or GENERIC_SPIRAM.
