PlatformIO VS esp32-course

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.

I got some resources to get knowldege of LVGL and FreeRTOS. - https://learnesp32.com/ (Concepts of FreeRTOS, task, event, queue,) - https://lvgl.academy/ (You can learn how to use LVGL with freeRTOS, but It is old version of LVGL) - https://www.udemy.com/course/iot-application-development-with-the-esp32-using-the-esp-idf/ (ESP32 But you can notice how to work task and message queue event in WiFi and webserver, littile bit complex )

The big thing is the examples they have. I use Visual Studio Code with the ESP-idf extention, and if I want to learn a new functionality, I load an example and break it down. There is also the website https://learnesp32.com, which does a very high level understanding of the code, but if you have prior experience with other micro-controllers, than that probably isn't necessary.

A previous thread recommended this course: https://learnesp32.com/

The best place is the course offered by https://learnesp32.com . It's a paid course but covers all basic and intermediate topics

And yes! LearnESP32.com by Mair is a great way to getting started. Checkout his github page for valuable info.

Then I moved on to some example apps with ESP IDF, and those compiled, flashed, and worked perfectly first try. So then I found this tutorial website, and after about a day, I was doing all sorts of fancy stuff. That was the best $50 I had spent as far as understanding all the core bits very well and knowing my way around.

When I was new to ESP32 development, I found the videos at https://learnesp32.com/ to be very valuable. I felt very comfortable with ESP IDF development afterwards. Well worth $50.
