Thank you for your reply. Still have a couple of questions!
1) Do I need to search for a book/tutorial or series about the Arduino itself or embedded programming on Arduino? About the time, I can manage my schedule to dedicate enough time to that.
2) Now I only have a blue pill, some cables and USB connectors plus a STM32F411 Nucelo-64 board. Do I need more stuff to buy to get started and program a few embedded examples?
Thank you for your time and help.
Isn’t there any answer to my question, please?
