Re: does pico use the same coding as arduino
A Raspberry Pi Pico board is not an Arduino. The first thing I did with my first Pico was install the Pico tools in Arduino. I then took some Nano HID keyboard code and compiled and loaded it onto the Pico. It just worked, took only a few minutes.. Anyone familiar with Arduino will be up and runnin...

Re: Raspberry pi for industrial use
I run a home security camera system 24/7 since 2014.
OS on the SD/uSD, vidoes on a Western Digital Purple in an externally powered USB caddy.
The Sandisk A1 uSD have been the best ones so far.

Re: Digital Signage questions
Been a few years since I used Buildroot. Seem to remember it took a weekend to learn. I only had 3B+ back then and had to increase the swap file, still took hours and a single configure issue was a recompile. First compile took 13 hours and eventually wore out my uSD card.

Re: Digital Signage questions
I prefer PiCore for the single core Pi's if I have to use Linux.
There is a limited choice of apps so you need to search the repo.
http://www.tinycorelinux.net/13.x/armv6/tcz/
CLI image viewer feh.tcz?
I have done a lot with just shell script and Micropython in PiCore.

Depends on the libraries, the standard stuff like "blink" should be the same with maybe a GPIO number change.

Re: Digital Signage questions
I used PiCore Linux which runs from ram or Ultibo which only reads it's "OS" from uSD. Both don't care about power outs. The main issue would be file corruption when writing and power goes off? I started with Python and Pygame in 2012 on Pi's, was never happy with 24/7 use with this method.

Re: How I can do to start my raspberry pi 4b?
Not all USB sticks will work as PI boot devices.
Tried a few recently, used Imager to write the OS to the USB stick, shut down removed uSD and rebooted.
Not all worked.

Re: Identifying I2C devices.
It's in Pascal but should be easy enough to convert.

It basically checks for a response by reading the first register of each possible i2c address.

Re: Control Loops for Induction Motor Torque Vector control for EV applications
No, sort of. Pi's are A series CPU cores, R series ARM CPUs are the Realtime ones. But a Pico and some smart PIO coding might do it. This is typically a DSP application. However one of Liz's first Pi post was about the Pi's onboard DSP? Could the VPU/QPU's to do this? According to those that know th...
