pico-micropython-examples VS linux

You would have to look at the code to be sure. (I'm too lazy to look.) But if you want, you can use this code to ensure that you are using the PIO hardware (and that wouldn't have problems with interrupts): https://github.com/raspberrypi/pico-micropython-examples/blob/master/pio/pio_pwm.py

You can then look at the MicroPython pico examples and try adding the adc code to read the onboard temperature, and send it in the request. Then you can look for help on using the Adafruit_DHT code. Take small steps.

Python already exists for the pico. It is a micropython port. Once you've downloaded it, you have an interactive Python prompt and a filesystem you can place a main.py file in to run at reboot. MicroPython is a fantastic way to start with microprocessors.

Thank you so much for your help. is resp=b"" equal to resp=bytes() ? and why the author did not use decode or encode? see this please-> https://github.com/raspberrypi/pico-micropython-examples/blob/master/uart/loopback/uart.py

When working with the Pico and MicroPython, I've found an endless amount of use from the Pico MicroPython Examples repository on GitHub.

Line 7 - 9: Pio assembler commands as documented in the official documentation. In MicroPython, there are subtle differences to the naming conventions, so be sure to read the community documentation and also browse the examples

Fan control generally involves hysteresis. This means a cooling fan turns on at one temperature, and then turns off once temperature has fallen to another lower temperature. This avoids cycling the fan on and off too much. The difference between those two temperatures is hysteresis. The default hysteresis is 10°C and maybe the fan never manages to cool the CPU to 45°C. A parameter has been added to change hysteresis: https://github.com/raspberrypi/linux/commit/fa390133fd17f2cc6aa5a7d2e472c073a1115fe1

I see that the PR against the Raspberry Pi linux repo is out [0]. Interestingly they are introducing a BCM2712 defconfig with a 64k default page size.

[0] - https://github.com/raspberrypi/linux/pull/5618

and can grab their patched kernel source here ( use the dtbs and overlays and kernel from your compiled version)

Also was your pi issue related to this? https://github.com/raspberrypi/linux/issues/3381 or what do you mean jittery, unstable?

Could be related to the driver load order/blacklisting (https://github.com/raspberrypi/linux/issues/435) Or couple of people report configuring the dtoverlay=imx477 in the boot config helped (https://raw.githubusercontent.com/raspberrypi/firmware/master/boot/overlays/README)

thanks, I also found this: https://github.com/raspberrypi/linux/issues/5398

And ready! :)

Well, it depends for whom. Also, you need adequate software and hardware. About wireless, the chipset in an RPi4 is designed for clients, not APs, and its capabilities on having multiple clients are quite limited:

Routers like the Omnia Turris, Mikrotik, PC Engines... use specific mini PCIe cards that can be as expensive as a full Raspberry Pi 4, just for the wireless.
