I blinked my first LED by using a 51 microcontroller with the KEIL IDE in 2005. I was super excited on this “magic”. Later, I studied how to program the AVR microcontrollers, such ATmega16, ATmega328, using the ICC AVR IDE. At that time, Arduino was not introduced to China. I had to buy various of AVR development boards to play and explore.
I learned TI MSP430, C2000, Arm microcontrollers at University of Illinois from my teacher Dan Block. I took almost all his courses/labs in control, signal processing and embedded system. At the same time, I learned STM32 microcontrollers from YouTube, Udemy etc.
From my experience, there is no short-cut on learning hands-on embedded programming. I always tried to make my hands dirty, be patient, be careful and be safe. Learning from the bare metal programming might be wise. Third-party optimized libraries are really for experts who have been very very familiar with the low level programming. Learn to read datasheet and learn to use oscilloscope are necessary.
I personally use
FreeRTOS on STM32 microcontrollers with STM32CubeIDE, CMSIS, HALTI-RTOS (SYS/BIOS) on TI C2000 microcontroller with CCS, Bitfield, Driverlib
Cyber-physical System: systems where software and hardware components are seamlessly integrated towards performing well defined tasks.
Real-time System: an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints.
Embedded System: a microprocessor or microcontroller based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. At the core is an integrated circuit designed to carry out computation for real-time operations.
