duino-coin VS PlatformIO

I have been checking out this project called duino-coin. Basically you can use Raspberry Pi's to mine their coin. I'm not too familiar with crypto so a few things are weird to me. The coin is centralised and as I've understood, the point of mining is to hash transactions (which is the whole point of decentralisation). How is it possible to mine and be centralised?

https://github.com/revoxhere/duino-coin It's not profitable at all tho.

https://github.com/revoxhere/duino-coin it says here that the uno makes 15-20 duco per day which is 0.0018 USD. But I actually only make 4 duco per day which is 0.0005 USD. I could be doing something wrong though. My Pi 4 (4gb, 32 bit) only makes 1.4 duco, and that is on the easy difficulty. On the medium setting I only make 0.6. Idk about the power costs though.

I suggest reading the main website (duinocoin.com) or the whitepaper

Hello, as stated on the releases page on github:

For the ESP32 in read mode, we've successfully developed a project using PlatformIO that accepts the key during build time and stores it in memory.

Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino.

PlatformIO together with avr-stub can be used to do source level debugging but there are some caveats.

Look into https://platformio.org/, it can abstract over a few RTOSes, and can show you which OSes work with which chips/boards.

If the HW looks like it works, you could also try alternate programming software. (e.g. TinyGo or PlatformIO)

You might have better luck with PlatformIO than the Arduino IDE; it's better at automatically choosing the serial port, though I can't say I've used it under Windows.

My other suggestion takes more work but will make your life oh so much better. Professionally I have used and highly recommend. https://platformio.org/ which is free!

Will you be doing embedded Linux? Embedded RTOS? Bare metal? Microcontrollers? SoC (say, FPGA with a hard processor core)?

You can do a lot with QEMU. https://bootlin.com/ has a lot of great, free training material.

https://bootlin.com/doc/training/embedded-linux-qemu/embedde...

is one of my favorites.

Learning to cross-compile, do embedded debugging, the process of booting an embedded system (which varies depending on the answers to the above questions), learning how to read a technical reference for the processor you’re using as well as for peripherals you’re likely to interact with - SPI, i2c, UART, maybe PCIe, are all handy skills. Learn a bit about JTAG, hardware, reading schematics, etc. Even being able solder is helpful.

There may be books (I had a great embedded Linux book when I started) but there are lots of online materials too. Check out https://platformio.org/

There are fun embedded boards and projects for microcontrollers too - micropython on an rpi pico, tinygo, eLua, etc.
